我在多线程环境中使用curl版本7.15.5。每个线程正在初始化并释放它自己的卷曲对象。以下是为每个线程执行的代码:libcurl http post timeout
CURL* curl = curl_easy_init();
tRespBuffer respBuffer = {NULL, 0};
char errorBuf[CURL_ERROR_SIZE +1];
struct curl_slist *headers=NULL;
headers = curl_slist_append(headers, "Content-Type: text/xml; charset=gbk");
headers = curl_slist_append(headers, "Expect:");
curl_easy_setopt(curl, CURLOPT_URL, url_);
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
curl_easy_setopt(curl, CURLOPT_POSTFIELDS,encr.c_str());
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE,strlen(encr.c_str()));
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, HttpSmsServer::processHttpResponse);
curl_easy_setopt(curl, CURLOPT_WRITEDATA, (void*)&respBuffer);
curl_easy_setopt(curl, CURLOPT_TIMEOUT, 20); // wait for 20 seconds before aborting the transacttion
curl_easy_setopt(curl, CURLOPT_ERRORBUFFER, errorBuf); // error returned if any..
curl_easy_setopt(curl, CURLOPT_NOSIGNAL, 1); // No signals allowed in case of multithreaded apps
res = curl_easy_perform(curl);
curl_slist_free_all(headers);
curl_easy_cleanup(curl);
所有这四个线程都将数据同时发送到http服务器。我看到一些POST请求的HTTP响应超时(〜3%的请求)。任何想法可能是超时的原因?我认为http服务器应该不会超过20秒来回应。
