当向服务器发送请求时，我如何才能看到curl所做的请求头?

当我向服务器发送请求时，我想看到curl所做的请求头。我要怎么检查呢?

当前回答

将报头转储到一个文件中，将响应的有效负载转储到另一个文件中

curl -k -v -u user:pass  "url" --trace-ascii headers.txt >> response.txt

下面是我的http客户端在php使post查询包含cookie:

function http_login_client($url, $params = "", $cookies_send = "" ){

    // Vars
    $cookies = array();
    $headers = getallheaders();

    // Perform a http post request to $ur1 using $params
    $ch = curl_init($url);
    $options = array(   CURLOPT_POST => 1,
                        CURLINFO_HEADER_OUT => true,
                        CURLOPT_POSTFIELDS => $params,
                        CURLOPT_RETURNTRANSFER => 1,
                        CURLOPT_HEADER => 1,
                        CURLOPT_COOKIE => $cookies_send,
                        CURLOPT_USERAGENT => $headers['User-Agent']
                    );

    curl_setopt_array($ch, $options);

    $response = curl_exec($ch);

///调试信息 echo $响应; var_dump (curl_getinfo (ch)美元); ///

    // Parse response and read cookies
    preg_match_all('/^Set-Cookie: (.*?)=(.*?);/m', $response, $matches);

    // Build an array with cookies
    foreach( $matches[1] as $index => $cookie )
        $cookies[$cookie] = $matches[2][$index];

    return $cookies;
} // end http_login_client

你可以通过使用"-"作为文件名直接将头文件转储到标准输出，例如查看头文件和内容，并遵循重定向，所有这些都在一个输出中:

curl -L -D - -s [url]

你可以使用-iv来查看

$> curl  -ivH "apikey:ad9ff3d36888957" --form  "file=@/home/mar/workspace/images/8.jpg" --form "language=eng" --form "isOverlayRequired=true" https://api.ocr.space/Parse/Image

我认为curl -verbose/-v是最简单的。它将输出请求头(以'>'为前缀的行)，而无需写入文件:

$ curl -v -I -H "Testing: Test header so you see this works" http://stackoverflow.com/
* About to connect() to stackoverflow.com port 80 (#0)
*   Trying 69.59.196.211... connected
* Connected to stackoverflow.com (69.59.196.211) port 80 (#0)

如下所示的命令将显示三个部分:请求头、响应头和数据(由CRLF分隔)。它避免了curl添加的技术信息和语法噪声。

curl -vs www.stackoverflow.com 2>&1 | sed '/^* /d; /bytes data]$/d; s/> //; s/< //'

该命令将产生如下输出:

GET / HTTP/1.1
