Python 示例代码

方法一：使用 requests 库

import requests
import json

# API 配置
base_url = "https://stockapi.com.cn/v1/base/day"
token = "你的token"  # 请替换为实际的token

# 请求参数
params = {
    "token": token,
    "code": "600004",
    "startDate": "2021-10-10",
    "endDate": "2021-10-15",
    "calculationCycle": 100
}

try:
    # 发送GET请求
    response = requests.get(base_url, params=params)
    
    # 检查响应状态
    if response.status_code == 200:
        data = response.json()
        print("请求成功！")
        print(json.dumps(data, indent=2, ensure_ascii=False))
    else:
        print(f"请求失败，状态码：{response.status_code}")
        print(f"响应内容：{response.text}")
        
except requests.exceptions.RequestException as e:
    print(f"请求异常：{e}")
      

方法二：使用 urllib 库（Python 标准库）

import urllib.request
import urllib.parse
import json

# API 配置
base_url = "https://stockapi.com.cn/v1/base/day"
token = "你的token"  # 请替换为实际的token

# 请求参数
params = {
    "token": token,
    "code": "600004",
    "startDate": "2021-10-10",
    "endDate": "2021-10-15",
    "calculationCycle": 100
}

# 构建完整的URL
query_string = urllib.parse.urlencode(params)
full_url = f"{base_url}?{query_string}"

try:
    # 发送GET请求
    with urllib.request.urlopen(full_url) as response:
        data = json.loads(response.read().decode('utf-8'))
        print("请求成功！")
        print(json.dumps(data, indent=2, ensure_ascii=False))
        
except urllib.error.HTTPError as e:
    print(f"HTTP错误：{e.code} - {e.reason}")
except urllib.error.URLError as e:
    print(f"URL错误：{e.reason}")
except Exception as e:
    print(f"其他错误：{e}")
      

Java 示例代码

方法一：使用 HttpURLConnection（Java 标准库）

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLEncoder;
import java.nio.charset.StandardCharsets;

public class StockApiDemo {
    private static final String BASE_URL = "https://stockapi.com.cn/v1/base/day";
    private static final String TOKEN = "你的token"; // 请替换为实际的token
    
    public static void main(String[] args) {
        try {
            // 构建请求参数
            String params = "token=" + URLEncoder.encode(TOKEN, StandardCharsets.UTF_8) +
                           "&code=" + URLEncoder.encode("600004", StandardCharsets.UTF_8) +
                           "&startDate=" + URLEncoder.encode("2021-10-10", StandardCharsets.UTF_8) +
                           "&endDate=" + URLEncoder.encode("2021-10-15", StandardCharsets.UTF_8) +
                           "&calculationCycle=" + URLEncoder.encode("100", StandardCharsets.UTF_8);
            
            // 创建URL对象
            URL url = new URL(BASE_URL + "?" + params);
            
            // 创建HTTP连接
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Accept", "application/json");
            connection.setRequestProperty("User-Agent", "Java-StockAPI-Client/1.0");
            
            // 获取响应码
            int responseCode = connection.getResponseCode();
            
            if (responseCode == HttpURLConnection.HTTP_OK) {
                // 读取响应内容
                BufferedReader reader = new BufferedReader(
                    new InputStreamReader(connection.getInputStream(), StandardCharsets.UTF_8));
                StringBuilder response = new StringBuilder();
                String line;
                
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();
                
                System.out.println("请求成功！");
                System.out.println("响应内容：" + response.toString());
            } else {
                System.out.println("请求失败，状态码：" + responseCode);
                
                // 读取错误响应
                BufferedReader errorReader = new BufferedReader(
                    new InputStreamReader(connection.getErrorStream(), StandardCharsets.UTF_8));
                StringBuilder errorResponse = new StringBuilder();
                String errorLine;
                
                while ((errorLine = errorReader.readLine()) != null) {
                    errorResponse.append(errorLine);
                }
                errorReader.close();
                
                System.out.println("错误内容：" + errorResponse.toString());
            }
            
            connection.disconnect();
            
        } catch (IOException e) {
            System.err.println("请求异常：" + e.getMessage());
            e.printStackTrace();
        }
    }
}
      

方法二：使用 OkHttp 库（推荐）

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
import okhttp3.HttpUrl;
import java.io.IOException;
import java.util.concurrent.TimeUnit;

public class StockApiOkHttpDemo {
    private static final String BASE_URL = "https://stockapi.com.cn/v1/base/day";
    private static final String TOKEN = "你的token"; // 请替换为实际的token
    
    public static void main(String[] args) {
        // 创建OkHttp客户端
        OkHttpClient client = new OkHttpClient.Builder()
            .connectTimeout(30, TimeUnit.SECONDS)
            .readTimeout(30, TimeUnit.SECONDS)
            .build();
        
        try {
            // 构建URL和参数
            HttpUrl.Builder urlBuilder = HttpUrl.parse(BASE_URL).newBuilder();
            urlBuilder.addQueryParameter("token", TOKEN);
            urlBuilder.addQueryParameter("code", "600004");
            urlBuilder.addQueryParameter("startDate", "2021-10-10");
            urlBuilder.addQueryParameter("endDate", "2021-10-15");
            urlBuilder.addQueryParameter("calculationCycle", "100");
            
            String url = urlBuilder.build().toString();
            
            // 创建请求
            Request request = new Request.Builder()
                .url(url)
                .addHeader("Accept", "application/json")
                .addHeader("User-Agent", "Java-OkHttp-StockAPI-Client/1.0")
                .build();
            
            // 执行请求
            try (Response response = client.newCall(request).execute()) {
                if (response.isSuccessful()) {
                    String responseBody = response.body().string();
                    System.out.println("请求成功！");
                    System.out.println("响应内容：" + responseBody);
                } else {
                    System.out.println("请求失败，状态码：" + response.code());
                    System.out.println("错误内容：" + response.body().string());
                }
            }
            
        } catch (IOException e) {
            System.err.println("请求异常：" + e.getMessage());
            e.printStackTrace();
        } finally {
            // 关闭客户端连接池
            client.dispatcher().executorService().shutdown();
            client.connectionPool().evictAll();
        }
    }
}
      

Maven 依赖配置

如果使用 OkHttp 库，需要在 pom.xml 中添加以下依赖：

<dependency>
    <groupId>com.squareup.okhttp3</groupId>
    <artifactId>okhttp</artifactId>
    <version>4.12.0</version>
</dependency>
      

Gradle 依赖配置

如果使用 Gradle，在 build.gradle 中添加：

implementation 'com.squareup.okhttp3:okhttp:4.12.0'
      

PHP 示例代码

方法一：使用 cURL

<?php
// API 配置
$baseUrl = "https://stockapi.com.cn/v1/base/day";
$token = "你的token"; // 请替换为实际的token

// 请求参数
$params = [
    'token' => $token,
    'code' => '600004',
    'startDate' => '2021-10-10',
    'endDate' => '2021-10-15',
    'calculationCycle' => 100
];

// 构建完整URL
$url = $baseUrl . '?' . http_build_query($params);

// 初始化cURL
$ch = curl_init();

// 设置cURL选项
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP-StockAPI-Client/1.0');
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Accept: application/json',
    'Content-Type: application/json'
]);

// 执行请求
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$error = curl_error($ch);

// 关闭cURL
curl_close($ch);

// 处理响应
if ($error) {
    echo "请求错误: " . $error . "\n";
} elseif ($httpCode === 200) {
    echo "请求成功！\n";
    $data = json_decode($response, true);
    echo "响应内容: " . json_encode($data, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE) . "\n";
} else {
    echo "请求失败，状态码: " . $httpCode . "\n";
    echo "响应内容: " . $response . "\n";
}
?>
      

方法二：使用 file_get_contents

<?php
// API 配置
$baseUrl = "https://stockapi.com.cn/v1/base/day";
$token = "你的token"; // 请替换为实际的token

// 请求参数
$params = [
    'token' => $token,
    'code' => '600004',
    'startDate' => '2021-10-10',
    'endDate' => '2021-10-15',
    'calculationCycle' => 100
];

// 构建完整URL
$url = $baseUrl . '?' . http_build_query($params);

// 创建上下文
$context = stream_context_create([
    'http' => [
        'method' => 'GET',
        'header' => [
            'Accept: application/json',
            'User-Agent: PHP-StockAPI-Client/1.0'
        ],
        'timeout' => 30
    ]
]);

// 发送请求
$response = @file_get_contents($url, false, $context);

if ($response === false) {
    echo "请求失败\n";
    $error = error_get_last();
    echo "错误信息: " . $error['message'] . "\n";
} else {
    echo "请求成功！\n";
    $data = json_decode($response, true);
    echo "响应内容: " . json_encode($data, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE) . "\n";
}
?>
      

方法三：使用 Guzzle HTTP 库

<?php
require_once 'vendor/autoload.php';

use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;

// API 配置
$baseUrl = "https://stockapi.com.cn/v1/base/day";
$token = "你的token"; // 请替换为实际的token

// 请求参数
$params = [
    'token' => $token,
    'code' => '600004',
    'startDate' => '2021-10-10',
    'endDate' => '2021-10-15',
    'calculationCycle' => 100
];

// 创建HTTP客户端
$client = new Client([
    'timeout' => 30,
    'headers' => [
        'Accept' => 'application/json',
        'User-Agent' => 'PHP-Guzzle-StockAPI-Client/1.0'
    ]
]);

try {
    // 发送GET请求
    $response = $client->get($baseUrl, [
        'query' => $params
    ]);
    
    if ($response->getStatusCode() === 200) {
        echo "请求成功！\n";
        $body = $response->getBody()->getContents();
        $data = json_decode($body, true);
        echo "响应内容: " . json_encode($data, JSON_PRETTY_PRINT | JSON_UNESCAPED_UNICODE) . "\n";
    } else {
        echo "请求失败，状态码: " . $response->getStatusCode() . "\n";
        echo "响应内容: " . $response->getBody()->getContents() . "\n";
    }
    
} catch (RequestException $e) {
    echo "请求异常: " . $e->getMessage() . "\n";
    if ($e->hasResponse()) {
        echo "错误响应: " . $e->getResponse()->getBody()->getContents() . "\n";
    }
} catch (Exception $e) {
    echo "其他异常: " . $e->getMessage() . "\n";
}
?>
      

Composer 依赖安装

如果使用 Guzzle HTTP 库，需要通过 Composer 安装：

composer require guzzlehttp/guzzle
      

或者在 composer.json 中添加依赖：

{
    "require": {
        "guzzlehttp/guzzle": "^7.0"
    }
}
      

C++ 示例代码

使用 libcurl 库

#include <iostream>
 #include <string>
 #include <curl/curl.h>
 #include <json/json.h>

// 回调函数用于接收响应数据
size_t WriteCallback(void* contents, size_t size, size_t nmemb, std::string* response) {
    size_t totalSize = size * nmemb;
    response->append((char*)contents, totalSize);
    return totalSize;
}

int main() {
    // API 配置
    const std::string baseUrl = "https://stockapi.com.cn/v1/base/day";
    const std::string token = "你的token"; // 请替换为实际的token
    
    // 构建完整URL
    std::string url = baseUrl + "?token=" + token + 
                     "&code=600004&startDate=2021-10-10&endDate=2021-10-15&calculationCycle=100";
    
    // 初始化libcurl
    curl_global_init(CURL_GLOBAL_DEFAULT);
    CURL* curl = curl_easy_init();
    
    if (curl) {
        std::string response;
        
        // 设置URL
        curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
        
        // 设置回调函数
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response);
        
        // 设置超时
        curl_easy_setopt(curl, CURLOPT_TIMEOUT, 30L);
        
        // 设置User-Agent
        curl_easy_setopt(curl, CURLOPT_USERAGENT, "CPP-StockAPI-Client/1.0");
        
        // 设置请求头
        struct curl_slist* headers = nullptr;
        headers = curl_slist_append(headers, "Accept: application/json");
        curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
        
        // 执行请求
        CURLcode res = curl_easy_perform(curl);
        
        if (res != CURLE_OK) {
             std::cerr << "请求失败: " << curl_easy_strerror(res) << std::endl;
        } else {
            long httpCode;
            curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, &httpCode);
            
            if (httpCode == 200) {
                std::cout << "请求成功！" << std::endl;
                 std::cout << "响应内容: " << response << std::endl;
                
                // 解析JSON（需要jsoncpp库）
                Json::Value jsonData;
                Json::Reader reader;
                if (reader.parse(response, jsonData)) {
                    std::cout << "JSON解析成功" << std::endl;
                     // 可以进一步处理JSON数据
                     if (jsonData.isMember("data") && jsonData["data"].isArray()) {
                         std::cout << "数据条数: " << jsonData["data"].size() << std::endl;
                    }
                } else {
                    std::cout << "JSON解析失败" << std::endl;
                }
            } else {
                std::cout << "请求失败，状态码: " << httpCode << std::endl;
                 std::cout << "响应内容: " << response << std::endl;
            }
        }
        
        // 清理
        curl_slist_free_all(headers);
        curl_easy_cleanup(curl);
    } else {
        std::cerr << "初始化curl失败" << std::endl;
    }
    
    curl_global_cleanup();
    return 0;
}
      

使用 cpprestsdk 库（现代C++异步方式）

#include <iostream>
 #include <string>
 #include <cpprest/http_client.h>
 #include <cpprest/filestream.h>
 #include <cpprest/uri.h>
 #include <cpprest/json.h>

    const std::string token = "你的token"; // 请替换为实际的token
    
    try {
        // 构建URI
        uri_builder builder(utility::conversions::to_string_t(baseUrl));
        builder.append_query(U("token"), utility::conversions::to_string_t(token));
        builder.append_query(U("code"), U("600004"));
        builder.append_query(U("startDate"), U("2021-10-10"));
        builder.append_query(U("endDate"), U("2021-10-15"));
        builder.append_query(U("calculationCycle"), U("100"));
        
        // 创建HTTP客户端
        http_client client(builder.to_uri());
        
        // 创建请求
        http_request request(methods::GET);
        request.headers().add(U("Accept"), U("application/json"));
        request.headers().add(U("User-Agent"), U("CPP-RestSDK-StockAPI-Client/1.0"));
        
        // 发送请求并等待响应
        client.request(request)
        .then([](http_response response) {
             std::wcout << L"状态码: " << response.status_code() << std::endl;
            
            if (response.status_code() == status_codes::OK) {
                return response.extract_json();
            } else {
                std::wcout << L"请求失败，状态码: " << response.status_code() << std::endl;
                return pplx::task_from_result(json::value());
            }
        })
        .then([](json::value jsonResponse) {
            if (!jsonResponse.is_null()) {
                std::wcout << L"请求成功！" << std::endl;
                 std::wcout << L"响应内容: " << jsonResponse.serialize() << std::endl;
                
                // 处理JSON数据
                if (jsonResponse.has_field(U("data")) && jsonResponse[U("data")].is_array()) {
                    auto dataArray = jsonResponse[U("data")].as_array();
                    std::wcout << L"数据条数: " << dataArray.size() << std::endl;

编译说明

使用 libcurl 和 json-c（推荐）

# Ubuntu/Debian
sudo apt-get update
sudo apt-get install libcurl4-openssl-dev libjson-c-dev

# 编译
gcc -std=c99 -o stock_api main.c -lcurl -ljson-c

# CentOS/RHEL
sudo yum install libcurl-devel json-c-devel
# 或者使用 dnf (较新版本)
sudo dnf install libcurl-devel json-c-devel

# 编译
gcc -std=c99 -o stock_api main.c -lcurl -ljson-c

# macOS (使用 Homebrew)
brew install curl json-c
gcc -std=c99 -o stock_api main.c -lcurl -ljson-c
      

Windows 编译（使用 MinGW）

# 安装 MSYS2 和 MinGW
# 然后安装依赖
pacman -S mingw-w64-x86_64-curl mingw-w64-x86_64-json-c

# 编译 libcurl 版本
gcc -std=c99 -o stock_api.exe main.c -lcurl -ljson-c

# 编译 WinINet 版本（仅Windows标准库）
gcc -std=c99 -o stock_api_wininet.exe main_wininet.c -lwininet
      

使用 CMake

cmake_minimum_required(VERSION 3.10)
project(StockAPIDemo C)

set(CMAKE_C_STANDARD 99)
set(CMAKE_C_STANDARD_REQUIRED ON)

# 查找依赖库

Node.js 示例代码

使用 axios 库（推荐）

const axios = require('axios');

// API 配置
const BASE_URL = 'https://stockapi.com.cn/v1/base/day';
const TOKEN = '你的token'; // 请替换为实际的token

// 请求参数
const params = {

            console.log(`\n数据条数: ${data.data.length}`);
            
            // 显示前3条数据
            const displayCount = Math.min(3, data.data.length);

注意事项

• Python：请确保已安装 requests 库：pip install requests
• Java：推荐使用 OkHttp 库，需要添加相应的 Maven 或 Gradle 依赖
• PHP：确保启用了cURL扩展，或者使用file_get_contents时启用了allow_url_fopen
• PHP：使用Guzzle库时需要通过Composer安装：composer require guzzlehttp/guzzle
• C++：需要安装libcurl和jsoncpp开发库，或者使用cpprestsdk库
• C++：建议使用CMake进行项目管理，确保正确链接所需的库文件
• C++：在Windows环境下可以使用vcpkg包管理器安装依赖：vcpkg install curl jsoncpp cpprestsdk
• C#：推荐使用HttpClient进行异步HTTP请求，需要安装Newtonsoft.Json包处理JSON
• C#：使用RestSharp库可以简化HTTP请求代码，通过NuGet安装相关依赖包
• C#：项目需要.NET Framework 4.6.1+或.NET Core 2.0+/.NET 5+支持
• C语言：推荐使用libcurl库进行HTTP请求，配合json-c库解析JSON数据
• C语言：在Windows环境下可以使用WinINet API（仅限Windows系统），或使用MSYS2/MinGW安装libcurl
• C语言：编译时需要链接相应的库文件（-lcurl -ljson-c），注意内存管理，及时释放分配的内存资源
• Node.js：推荐使用axios库进行HTTP请求，需要通过npm安装：npm install axios
• Node.js：可以使用内置的https模块，无需额外依赖，适合轻量级应用
• Node.js：node-fetch库提供类似浏览器fetch API的体验，Express.js适合构建API服务器
• Node.js：建议使用环境变量管理API token，可以安装dotenv库：npm install dotenv
• 请将示例代码中的 "你的token" 替换为实际的API访问令牌
• 股票代码需要使用正确的格式（如：600004）
• 日期格式必须为 YYYY-MM-DD
• 请注意API的调用频率限制
• 建议设置合适的连接超时和读取超时时间
• 注意处理字符编码，使用 UTF-8
• 在生产环境中，建议使用环境变量或配置文件来管理API token

错误处理

常见的错误响应：

{
  "msg": "亲！您传入的token不存在，请检查token是否正确。地址：https://stockapi.com.cn/",
  "code": 60048
}
      

请确保：

• Token 有效且正确
• 网络连接正常
• 请求参数格式正确
