PHP -如何检查Curl是否真的是post/send请求？

Question

我基本上使用Curl和PHP创建了一个脚本，将数据发送到网站，例如主机、端口和时间。然后提交数据。我如何知道Curl/PHP是否真的将这些数据发送到web页面？

$fullcurl = "?host=".$host."&time=".$time.";

有没有办法查看他们是否真的将数据发送到我MYSQL上的那些URL？

您可以使用curl_getinfo()来获取响应的状态码，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，如果您向某种返回请求结果信息的API发出请求，则需要实际获取该结果并对其进行解析。这是非常特定于API的，但这里有一个示例：

// 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);
}

Answer 2

为了确保curl发送某些内容，您需要一个数据包嗅探器。例如，您可以尝试使用wireshark。

我希望这能帮到你
