函数调用失败并返回错误时,可以按照以下步骤进行排查和解决: 确认具体环境: 首先,确保你的开发环境已经正确安装了libcurl库,并且你的程序已经正确链接了这个库。 检查你的网络环境,确保网络连接正常,且目标服务器可达。检查初始化步骤: 在调用curl_easy_perform()之前,你需要确保已经正确初始化了CURL会话。这通常...
When you make a call tohttps://www.google.com, the code will work fine. This made me look into the self-signed certificates and my HTTPS Server. Apparently, the issue may be with HTTPS Server sending SSL close_notify. Not using curl error buff. I was relying oncurl_easy_strerror(res)...
发现是因为自己加了一个这个 curl_easy_setopt(pCURL, CURLOPT_SSL_OPTIONS, (long)CURLSSLOPT_ALLOW_BEAST | CURLSSLOPT_NO_REVOKE); 后来改成 curl_easy_setopt(pCURL, CURLOPT_SSL_VERIFYPEER, 0); 就可以了== 坑到自己了
在使用libcurl时, jwisp发现, curl_easy_perform是阻塞的方式进行下载的, curl_easy_perform执行后,程序会在这里阻塞等待下载结束(成功结束或者失败结束).此时若正常下载一段时间后,进行网络中断, curl_easy_perform并不会返回失败,而是阻塞整个程序卡在这里,此时即使网络连接重新恢复, curl_easy_perform也无法恢复继续...
curl_easy_perform_返回值说明
2.返回值为CURLE_UNSUPPORTED_PROTOCOL (1) 当URL中使用了不支持的协议时,curl_easy_perform会返回CURLE_UNSUPPORTED_PROTOCOL。这意味着libcurl无法处理该协议的请求,可能是由于缺少相应的协议处理模块。 3.返回值为CURLE_FAILED_INIT (2) 当libcurl库初始化失败时,curl_easy_perform会返回CURLE_FAILED_INIT。这可...
