Curl or File_get_contents Gets the method that requires the authorization page

Original: http://blog.csdn.net/fdipzone/article/details/44475801

The original view is clearer because the blog's editor is rotten. Go back to backup.

Today because of work needs, need to use curl/file_get_contents to obtain authorization (Authorization) of the page content, resolved after writing this article to share to everyone

PHP Curl extension, the ability to initiate Post/get requests on the server side, access to the page, and the ability to retrieve the page return data.

For example, to get the page:http://localhost/server.php

<? PHP $content isset ($_post$_post[' content ']: '; Header (' Content-type:application/json '); echo json_encode (array(' content ' =$content));? >

Get server.php Page Using Curl

<?PHP$url= ' http://localhost/server.php ';$param=Array(' content ' = ' Fdipzone blog ');$ch=curl_init (); curl_setopt ($ch, Curlopt_url,$url); curl_setopt ($ch, Curlopt_post,true); curl_setopt ($ch, Curlopt_postfields,Http_build_query($param)); Curl_setopt ($ch, Curlopt_returntransfer,true);$ret= Curl_exec ($ch);$retinfo= Curl_getinfo ($ch); Curl_close ($ch);if($retinfo[' Http_code ']==200){    $data= Json_decode ($ret,true); Print_r($data);}Else{    Echo' POST Fail ';}?>

If the service does not have a php curl extension installed, using file_get_contents can also implement a request to get the page back data

<?PHP$url= ' http://localhost/server.php ';$param=Array(' content ' = ' Fdipzone blog ');$opt=Array(    ' http ' =Array(        ' Method ' = ' POST ', ' header ' = ' content-type:application/x-www-form-urlencoded ', ' content ' =Http_build_query($param)    ));$context=stream_context_create($opt);$ret=file_get_contents($url,false,$context);if($ret){    $data= Json_decode ($ret,true); Print_r($data);}Else{    Echo' POST Fail ';}?>

The results returned using curl and file_get_contents are the same.

Array (    = = Fdipzone blog)

For pages that require authorization, such as pages that use Htpasswd+.htaccess to set Directory Access, the 401 unauthorized error is returned directly with the method above .

This example does not use htpasswd+.htaccess to control access, but uses the two server parameters $_server[' Php_auth_user ' and $_server[' PHP_AUTH_PW '].

To learn about Htpasswd+.htaccess's friends, you can visit the article I wrote earlier, "Generate encrypted password files using Apache htpasswd, and use. htaccess to control Directory Access"

http://localhost/server.php modified to:

<?PHPif(!isset($_server[' Php_auth_user '])) {     Header(' Www-authenticate:basic realm= ' localhost '); Header("Http/1.0 401 Unauthorized"); Exit; }Else{     if(($_server[' Php_auth_user ']!= "Fdipzone" | |$_server[' PHP_AUTH_PW ']!= "654321")) {        Header(' Www-authenticate:basic realm= ' localhost '); Header("Http/1.0 401 Unauthorized"); Exit; }}$content=isset($_post[' content ']?$_post[' content ']: ';Header(' Content-type:application/json ');EchoJson_encode (Array(' content ' =$content));?>

Set account number:fdipzone password:654321

In Curl, one of the parameters is curlopt_userpwd, and we can use this parameter to send the password of the account in the past upon request.

<?PHP$url= ' http://localhost/server.php ';$param=Array(' content ' = ' Fdipzone blog ');$ch=curl_init (); curl_setopt ($ch, Curlopt_url,$url); curl_setopt ($ch, Curlopt_post,true); curl_setopt ($ch, Curlopt_postfields,Http_build_query($param)); Curl_setopt ($ch, Curlopt_returntransfer,true); curl_setopt ($ch, Curlopt_userpwd, ' fdipzone:654321 ');//Add this sentence$ret= Curl_exec ($ch);$retinfo= Curl_getinfo ($ch); Curl_close ($ch);if($retinfo[' Http_code ']==200){    $data= Json_decode ($ret,true); Print_r($data);}Else{    Echo' POST Fail ';}?>

and file_get_contents if you want to send the account and password, you need to manually splice header
File_get_contents The requested program is modified to:

<?PHP$url= ' http://localhost/server.php ';$param=Array(' content ' = ' Fdipzone blog ');$auth=sprintf(' Authorization:basic%s ',Base64_encode(' fdipzone:654321 '));//Add this sentence$opt=Array(    ' http ' =Array(        ' Method ' = ' POST ', ' header ' = ' content-type:application/x-www-form-urlencoded\r\n '.$auth." \ r \ n ",//Add the $auth to the header' Content ' =Http_build_query($param)    ));$context=stream_context_create($opt);$ret=file_get_contents($url,false,$context);if($ret){    $data= Json_decode ($ret,true); Print_r($data);}Else{    Echo' POST Fail ';}?>

Curl or file_get_contents get a way to authorize pages
