PHP 的get、post请求小记

PHP发送GET、POST请求

发送 GET 请求

1.调用 file_get_contents 函数，以 get 方式获取内容

<?php
    $url = "http://username:password@localhost:81/phpGetTest/index.php";
    $html = file_get_contents($url);
    echo $html;
?>

2.使用curl库，使用curl库之前，可能需要查看一下php.ini是否已经打开了curl扩展

<?php
    $url = "http://username:password@localhost:81/phpGetTest/index.php";
    $ch = curl_init();
    $timeout = 5;
    curl_setopt ($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $file_contents = curl_exec($ch);
    curl_close($ch);
    echo $file_contents;
?>

发送 POST 请求

1.使用curl库，发送 xml 数据

<?php
    $postUrl = "http://username:password@localhost:81/phpPostTest/index.php";
    $xmlData = "
        <xml>
            <ToUserName>ad775b217</ToUserName>
            <FromUserName>tWy3zC3xUgQMR5coXif5SA</FromUserName>
            <CreateTime>1366181013</CreateTime>
            <MsgType>text</MsgType>
            <Content>我的测试</Content>
            <MsgId>5867702771251151243</MsgId>
        </xml>";
    $header[] = "Content-type: text/xml"; //定义content-type为xml
    $ch = curl_init ();
    curl_setopt($ch, CURLOPT_URL, $postUrl);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $xmlData);
    $response = curl_exec($ch);
    if(curl_errno($ch)) {
        print curl_error($ch);
    }
    curl_close($ch);
    echo $response;
?>
