How to get info on sent PHP curl request
提问by user101289
I'm trying to debug a curl request to a webservice 'getToken' endpoint.
我正在尝试调试对 web 服务“getToken”端点的 curl 请求。
I'm not 100% confident that the URL and the auth info is getting written in to the curl handle correctly.
我不是 100% 确信 URL 和身份验证信息是否正确写入 curl 句柄。
I'm trying to use curl_getinfo($ch, CURLINFO_HEADER_OUT);to capture the sent request, but it doesn't give me much info. Is there a way to get more in depth diagnostics about what the actual curl request looks like?
我试图用来curl_getinfo($ch, CURLINFO_HEADER_OUT);捕获发送的请求，但它没有给我太多信息。有没有办法更深入地诊断出实际的 curl 请求是什么样的？
Here's the code:
这是代码：
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HEADER, 1); // just getting header to see if we got an auth token
curl_setopt($ch, CURLOPT_FILE, $fh);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLINFO_HEADER_OUT, 1); // capture the header info
curl_setopt($ch, CURLOPT_VERBOSE, 1); // turn verbose on
// execute the curl request
$rh = fopen("request.txt", "w"); // open request file handle
$verbose = fopen('php://temp', 'rw+');
curl_setopt($ch, CURLOPT_STDERR, $verbose);
curl_exec($ch); // execute request
$sent_request = curl_getinfo($ch, CURLINFO_HEADER_OUT);
fwrite($rh, $sent_request); // save the request info
fclose($rh);
!rewind($verbose);
$verboseLog = stream_get_contents($verbose);
echo "Verbose information:\n<pre>", htmlspecialchars($verboseLog), "</pre>\n";
This all works as far as it goes, but returns a 401 every time-- the API admin assures me that the username / pass I have is correct.
就目前而言，这一切都有效，但每次都会返回 401——API 管理员向我保证我拥有的用户名/通行证是正确的。
I was wondering if I'm somehow getting the URL value wrong, or not sending the right username / pass, but this info isn't printed in the request data saved:
我想知道我是否以某种方式获取了错误的 URL 值，或者没有发送正确的用户名/通行证，但此信息未打印在保存的请求数据中：
HEAD /export/auth HTTP/1.1
Authorization: Basic Y2FpcmRzdW5mYTpENWlAaVM4cw==
Host: webservices.mycompany.com
Accept: */*
You can see that the username/pass is not recorded (I assume for security). The endpoint URL I think is the hostvalue plus the start of the HEADvalue, so webservices.mycompany.com/export/auth?
您可以看到没有记录用户名/通行证（我假设是为了安全）。我认为端点 URL 是host值加上值的开头HEAD，所以webservices.mycompany.com/export/auth?
The "Verbose Information" statement prints nothing. Not sure why on this either!
“详细信息”语句不打印任何内容。也不知道为什么会这样！
Thanks for help.
感谢帮助。

If you set CURLINFO_HEADER_OUTto true, outgoing headers are available in the array returned by curl_getinfo(), under request_headerkey:
如果设置CURLINFO_HEADER_OUT为true，则传出标头在curl_getinfo(), 下返回的数组中可用request_header：
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://foo.com/bar");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "someusername:secretpassword");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
$info = curl_getinfo($ch);
print_r($info['request_header']);
This will print:
这将打印：
GET /bar HTTP/1.1
Authorization: Basic c29tZXVzZXJuYW1lOnNlY3JldHBhc3N3b3Jk
Host: foo.com
Accept: */*
Note the auth details are base64-encoded:
请注意，身份验证详细信息是 base64 编码的：
echo base64_decode('c29tZXVzZXJuYW1lOnNlY3JldHBhc3N3b3Jk');
// prints: someusername:secretpassword
Also note that username and password need to be percent-encoded to escape any URL reserved characters (/, ?, &, :and so on) they might contain:
另外请注意，用户名和密码必须是百分比编码逃避任何URL保留字符（/，?，&，:和如此），他们可能包含：
curl_setopt($ch, CURLOPT_USERPWD, urlencode($username).':'.urlencode($password));

You can also use a proxy tool like Charlesto capture the outgoing request headers, data, etc. by passing the proxy details through CURLOPT_PROXYto your curl_setopt_arraymethod.
您还可以使用Charles等代理工具通过将代理详细信息传递CURLOPT_PROXY给您的curl_setopt_array方法来捕获传出的请求标头、数据等。
For example:
例如：
$proxy = '127.0.0.1:8888';
$opt = array (
CURLOPT_URL => "http://www.example.com",
CURLOPT_PROXY => $proxy,
CURLOPT_POST => true,
CURLOPT_VERBOSE => true,
);
$ch = curl_init();
curl_setopt_array($ch, $opt);
curl_exec($ch);
curl_close($ch);

curl_getinfo()must be added before closing the curl handler
curl_getinfo()必须在关闭 curl 处理程序之前添加
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/bar");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "someusername:secretpassword");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
$info = curl_getinfo($ch);
print_r($info['request_header']);
curl_close($ch);

The request is printed in a request.txtwith details
请求打印在request.txt 中，并带有详细信息
$ch = curl_init();
$f = fopen('request.txt', 'w');
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_FOLLOWLOCATION => 1,
CURLOPT_VERBOSE => 1,
CURLOPT_STDERR => $f,
));
$response = curl_exec($ch);
fclose($f);
curl_close($ch);
You can also use curl_getinfo() function.
您还可以使用 curl_getinfo() 函数。
