帶有libcurl的http狀態碼？

Question

如何在調用curl_easy_perform後獲取HTTP狀態碼（例如200或500）？

Answer 1

http://curl.haxx.se/libcurl/c/curl_easy_getinfo.html

 
CURLINFO_RESPONSE_CODE 

Pass a pointer to a long to receive the last received HTTP or FTP code. This 
option was known as CURLINFO_HTTP_CODE in libcurl 7.10.7 and earlier. This 
will be zero if no server response code has been received. Note that a 
proxy's CONNECT response should be read with CURLINFO_HTTP_CONNECTCODE 
and not this. 

curl_code = curl_easy_perform (session); 
long http_code = 0; 
curl_easy_getinfo (session, CURLINFO_RESPONSE_CODE, &http_code); 
if (http_code == 200 && curl_code != CURLE_ABORTED_BY_CALLBACK) 
{ 
     //Succeeded 
} 
else 
{ 
     //Failed 
} 

Answer 2

對方回答是絕對正確的，但我也想補充一點，它可能不是明智的手工檢查錯誤代碼，該200代碼不是唯一代表成功的代碼。

我recoment使用的libcurl選項CURLOPT_FAILONERROR在被激活時將考慮的libcurl和400500 -category狀態的請求失敗，而且不會從執行返回CURLE_OK。
