PHP - 如何检查Curl实际发布/发送请求？

Question

我基本上使用Curl和PHP创建了一个脚本，该脚本将数据发送到网站，例如主机，端口和时间。然后它提交数据。我怎么知道Curl/PHP是否真的把这些数据发送到网页上？ “？主机=”。

$ fullcurl = $主机 “&时间=” $时间“;？

，看看他们是否实际发送数据到我的MySQL这些网址的任何方式

为了确保卷曲发的东西，你将需要一个数据包嗅探器。 你可以尝试wireshark例如，

我希望这会帮助你，

您可以使用curl_getinfo（）获得响应的状态代码如下所示：

// set up curl to point to your requested URL 
$ch = curl_init($fullcurl); 
// tell curl to return the result content instead of outputting it 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 

// execute the request, I'm assuming you don't care about the result content 
curl_exec($ch); 

if (curl_errno($ch)) { 
    // this would be your first hint that something went wrong 
    die('Couldn\'t send request: ' . curl_error($ch)); 
} else { 
    // check the HTTP status code of the request 
    $resultStatus = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
    if ($resultStatus == 200) { 
     // everything went better than expected 
    } else { 
     // the request did not complete as expected. common errors are 4xx 
     // (not found, bad request, etc.) and 5xx (usually concerning 
     // errors/exceptions in the remote script execution) 

     die('Request failed: HTTP status code: ' . $resultStatus); 
    } 
} 

curl_close($ch); 

参考：http://en.wikipedia.org/wiki/List_of_HTTP_status_codes

或者，如果你正在请求某种API的返回信息根据请求的结果，你需要真正得到结果并解析它。这是非常具体的API，但这里是一个例子：

// set up curl to point to your requested URL 
$ch = curl_init($fullcurl); 
// tell curl to return the result content instead of outputting it 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 

// execute the request, but this time we care about the result 
$result = curl_exec($ch); 

if (curl_errno($ch)) { 
    // this would be your first hint that something went wrong 
    die('Couldn\'t send request: ' . curl_error($ch)); 
} else { 
    // check the HTTP status code of the request 
    $resultStatus = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
    if ($resultStatus != 200) { 
     die('Request failed: HTTP status code: ' . $resultStatus); 
    } 
} 

curl_close($ch); 

// let's pretend this is the behaviour of the target server 
if ($result == 'ok') { 
    // everything went better than expected 
} else { 
    die('Request failed: Error: ' . $result); 
}
