PHP implements Curl or file_get_contents to obtain a method that requires an authorization page

This article mainly introduces the PHP implementation of curl or file_get_contents to obtain the required authorization page method, interested in the friend's reference, I hope to be helpful to everyone.

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

<?php $content = isset ($_post[' content ')? $_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, use the file_get_contents You can also implement an originating request to get the page return 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 (  [content] = 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, while using $_server[' Php_auth_user ' and $_server[' PHP_AUTH_PW '] These two server parameters.

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

<?php if (!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 '); echo json_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.

curl_setopt($ch, CURLOPT_USERPWD, '帐号:密码');

The program that Curl requests is modified to:

<?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 $opt = Array (' http ' = = ' + '   , ' method ' = ' POST ', ' header ' = ' + '   content-type:application/ X-www-form-urlencoded\r\n ". $auth." \ r \ n ",//Add $auth to Header   ' content ' = Http_build_query ($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 ';}?>
