libcurl进行post
main函数，初始化和清理curl
// 全局初始化curl
curl_global_init(CURL_GLOBAL_ALL);
std::string url = "http://xxxx";
std::string postParams = "aa=33&bb=33";
std::string response;
curl_post_req("http://sss", "aa=33&bb=33", response);
// 程序结束前清理curl
curl_global_cleanup();
发请求，设置参数，传入url、post参数、响应
检查response_code
bool curl_post_req(const std::string &url, const std::string &postParams, std::string &response)
{
CURL *curl = curl_easy_init();
CURLcode res;
if (curl)
{
// set params
curl_easy_setopt(curl, CURLOPT_POST, 1);
curl_easy_setopt(curl, CURLOPT_URL, url.c_str());
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, postParams.c_str());
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_call_back);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, (void *)&response);
// start req
res = curl_easy_perform(curl);
if (res != CURLE_OK) {
LOG(NOTICE) << "curl_easy_perform() failed: " + std::string(curl_easy_strerror(res));
return false;
}
long response_code = 0;
curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, &response_code);
if (response_code < 200 || response_code >= 300 || response.empty()) {
LOG(WARNING) << "http failed code: " << response_code;
return false;
}
else {
LOG(NOTICE) << "http success code: " << response_code;
}
}
// release curl
curl_easy_cleanup(curl);
return true;
}
回调函数
size_t write_call_back(void *contents, size_t size, size_t nmemb, std::string *userp) {
userp->append((char *) contents, size * nmemb);
return size * nmemb;
}
