此代码成功发送请求。我想生成此错误[CURLE_SEND_ERROR]。我可以在代码中修改什么以使此错误出现。
是否有选项可以使请求失败？
代码为：

if(strcmp(XMLFILE, SIM_INFO_RESPONSE_JSON)==0)
{
curl_easy_setopt(pCurl, CURLOPT_TIMEOUT, 50);// 120 seconds for Service Directory
}
else
{
curl_easy_setopt(pCurl, CURLOPT_TIMEOUT,(long)CONN_TIMEOUT);
}

        curl_easy_setopt(pCurl, CURLOPT_HEADER,0L);
    
    curl_easy_setopt(pCurl, CURLOPT_HTTPHEADER, psHeader);
    
    
    
    curl_easy_setopt(pCurl, CURLOPT_URL, psUrl);
    
    
    
    
    curl_easy_setopt(pCurl, CURLOPT_POSTFIELDSIZE,-1L);
    curl_easy_setopt(pCurl, CURLOPT_POSTFIELDS, psBuf);
    curl_easy_setopt(pCurl, CURLOPT_POST,1L);
    
    if (strcmp(isWiFi, "WiFi") == 0)
    {
        
        
        
        curl_easy_setopt(pCurl, CURLOPT_SSLCERTTYPE, "CRT");
        
        
        
        curl_easy_setopt(pCurl, CURLOPT_CAINFO, "rootCA.crt");
     
        
        curl_easy_setopt(pCurl, CURLOPT_SSL_VERIFYPEER, 0L);
        
        
        curl_easy_setopt(pCurl, CURLOPT_SSL_VERIFYHOST, 0L);
    }

#ifndef PRODMODE
curl_easy_setopt(pCurl, CURLOPT_VERBOSE,1L);
curl_easy_setopt(pCurl, CURLOPT_DEBUGFUNCTION, OnDebug);
#endif

    curl_easy_setopt(pCurl, CURLOPT_WRITEFUNCTION, WriteDataFunc);
    curl_easy_setopt(pCurl, CURLOPT_WRITEDATA, &nFd);

int i;

    for ( i = 0; i < 1; i++)
    {
        res = curl_easy_perform(pCurl);
    
        if (res == CURLE_OK)
            {
                ShowMsg("\r\n استقبال \r\n", 100);
                break;
            }
    }

我尝试将此错误显示为CURLE_SEND_ERROR
