解决方法
我不知道你是否真的意味着“并发”,但从描述中我相信你只想重用连接.如果只是对同一服务器执行两个请求,则应重用该连接
/* get the first document */ curl_easy_setopt(curl,CURLOPT_URL,"http://example.com/"); res = curl_easy_perform(curl); /* get another document from the same server using the same connection */ curl_easy_setopt(curl,"http://example.com/docs/"); res = curl_easy_perform(curl);
* About to connect() to example.com port 80 (#0) * Trying 192.0.32.10... * connected * Connected to example.com (192.0.32.10) port 80 (#0) [...] * HTTP/1.0 connection set to keep alive! < Connection: Keep-Alive Connection: Keep-Alive [...] * Connection #0 to host example.com left intact * Re-using existing connection! (#0) with host example.com * Connected to example.com (192.0.32.10) port 80 (#0)

在这种情况下,您需要多接口.多重联系说：
Enable multiple simultaneous transfers in the same thread without
making it complicated for the
application.
有关示例,请参阅multi-double.c(“只需下载两个HTTP文件！”).
