void setSSLSettings();
};#endif // CURLHTTP_H三。实现Cpp返回一个CURLcode方便出错时追踪错误
#include CurlHttp.hCurlHttp::CurlHttp() {curl curl_easy_init();if (!curl) {std::cerr Failed to initialize cURL std::endl;}
}CurlHttp::~CurlHttp() {if (curl) {curl_easy_cleanup(curl);}
}CURLcode CurlHttp::get(const std::string url, std::string response) {CURLcode res CURLE_FAILED_INIT;if (curl) {curl_easy_setopt(curl, CURLOPT_URL, url.c_str());curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);curl_easy_setopt(curl, CURLOPT_WRITEDATA, response);setSSLSettings();res curl_easy_perform(curl);if (res ! CURLE_OK) {std::cerr cURL GET request failed: curl_easy_strerror(res) std::endl;}}return res;
}CURLcode CurlHttp::post(const std::string url, const std::string data, std::string response) {CURLcode res CURLE_FAILED_INIT;if (curl) {curl_easy_setopt(curl, CURLOPT_URL, url.c_str());curl_easy_setopt(curl, CURLOPT_POSTFIELDS, data.c_str());curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, WriteCallback);curl_easy_setopt(curl, CURLOPT_WRITEDATA, response);setSSLSettings();// 设置请求头为JSON类型struct curl_slist* headers nullptr;headers curl_slist_append(headers, Content-Type: application/json);curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);res curl_easy_perform(curl);if (res !

}void CurlHttp::setSSLSettings() {// 设置证书路径curl_easy_setopt(curl, CURLOPT_CAINFO, /path/to/certificate.pem);// 设置私钥路径curl_easy_setopt(curl, CURLOPT_SSLKEY, /path/to/private.key);// 设置私钥密码如果有的话curl_easy_setopt(curl, CURLOPT_KEYPASSWD, password);
}四。测试函数
#include iostream
#include CurlHttp.hint main() {CurlHttp curlHttp;// 发起 GET 请求std::string url https://api.example.com/data;std::string response;CURLcode res curlHttp.get(url, response);if (res CURLE_OK) {std::cout GET request successful. Response: response std::endl;} else {std::cerr GET request failed. Error: curl_easy_strerror(res) std::endl;}// 发起 POST 请求url https://api.example.com/post;std::string data key1value1key2value2;response.clear();res curlHttp.post(url, data, response);if (res CURLE_OK) {std::cout POST request successful. Response: response std::endl;} else {std::cerr POST request failed. Error: curl_easy_strerror(res) std::endl;}// 下载文件url https://example.com/file.jpg;std::string savePath /path/to/save/file.jpg;res curlHttp.download(url, savePath);if (res CURLE_OK) {std::cout File downloaded successfully and saved at: savePath std::endl;} else {std::cerr File download failed. Error: curl_easy_strerror(res) std::endl;}// 上传文件url https://api.example.com/upload;std::string filePath /path/to/upload/file.txt;response.clear();res curlHttp.upload(url, filePath, response);if (res CURLE_OK) {std::cout File uploaded successfully. Response: response std::endl;} else {std::cerr File upload failed. Error: curl_easy_strerror(res) std::endl;}return 0;
}六。创建一个aidl文件
package com.example.yourpackage; // 替换为您的包名interface ICurlHttpService {int get(in String url, out String response);int post(in String url, in String data, out String response);int download(in String url, in String savePath);int upload(in String url, in String filePath, out String response);
}
