I'm trying to debug a curl request to a webservice 'getToken' endpoint.

I'm not 100% confident that the URL and the auth info is getting written in to the curl handle correctly.

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?

Here's the code:

$ch = curl_init($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.

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:

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 host value plus the start of the HEAD value, so webservices.mycompany.com/export/auth?

The "Verbose Information" statement prints nothing. Not sure why on this either!

Thanks for help.

如果设置CURLINFO_HEADER_OUT为true，则在返回的数组中可以使用传出标头curl_getinfo()，在request_header键下：

$ch = curl_init();
curl_setopt($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']);

这将打印：

GET /bar HTTP/1.1
Authorization: Basic c29tZXVzZXJuYW1lOnNlY3JldHBhc3N3b3Jk
Host: foo.com
Accept: */*

请注意，身份验证详细信息是 base64 编码的：

echo base64_decode('c29tZXVzZXJuYW1lOnNlY3JldHBhc3N3b3Jk');
// prints: someusername:secretpassword

另请注意，用户名和密码需要进行百分比编码以转义它们可能包含的任何 URL 保留字符（ /、?、&等）：:

curl_setopt($ch, CURLOPT_USERPWD, urlencode($username).':'.urlencode($password));

您还可以使用像Charles这样的代理工具，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。

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()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);

请求打印在request.txt中，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);

您还可以使用 curl_getinfo() 函数。
