PHP curl没有错误或结果

Question

When running the URL in browser prodivding the same credentials as in below code it generates an XML. However when running the below code from server I get no error message or any result. What am I doing wrong is it a IP-block, code error or?

According to documentation authentication is "basic HTTP/1.0 authentication request".

 <?php ini_set('display_startup_errors',1); ini_set('display_errors',1); error_reporting(-1); $username="myUsername"; $password="myPassword"; $url="http://domain.com?getFeed.php?id=3"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANYSAFE); curl_setopt($ch, CURLOPT_USERPWD, "$username:$password"); $file = curl_exec($ch); curl_close($ch); print $file; ?> 

Answer 1

同时添加以下代码，您将获得有关失败原因的正确信息。

curl_setopt($curlhandle, CURLOPT_VERBOSE, true);

Answer 2

let me quote documentation :

Returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.

as you do not set this option, $file is either true or false. but you just print it.

if ($file) {
    // success
    // get the body
} else {
    // failure
    // check curl_error()
}

Answer 3

One error you have is that you use the wrong HTTP authentication method, you use CURLAUTH_ANYSAFE , but you write that it should be

basic HTTP/1.0 authentication request

Thus, set the CURLOPT_HTTPAUTH to,

url_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);

(Or leave it blank since CURLAUTH_BASIC is the default)
