如何調用ajax返回php接口?針對這個問題,這篇文章詳細介紹了相對應的分析和解答,希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。
php是一個嵌套的縮寫名稱,是英文超級文本預處理語言,它的語法混合了C、Java、Perl以及php自創新的語法,主要用來做網站開發,許多小型網站都用php開發,因為php是開源的,從而使得php經久不衰。
php代碼如下:
<?php header('Content-Type: application/json'); header('Content-Type: text/html;charset=utf-8'); $email = $_GET['email']; $user = []; $conn = @mysql_connect("localhost","Test","123456") or die("Failed in connecting database"); mysql_select_db("Test",$conn); mysql_query("set names 'UTF-8'"); $query = "select * from UserInformation where email = '".$email."'"; $result = mysql_query($query); if (null == ($row = mysql_fetch_array($result))) { echo $_GET['callback']."(no such user)"; } else { $user['email'] = $email; $user['nickname'] = $row['nickname']; $user['portrait'] = $row['portrait']; echo $_GET['callback']."(".json_encode($user).")"; } ?>
js代碼如下:
<script> $.ajax({ url: "http://test.localhost/UserInterfaceForChatroom/UserInformation.php?email=pshuyue@gmail.com", type: "GET", dataType: 'jsonp', // crossDomain: true, success: function (result) { // data = $.parseJSON(result); // alert(data.nickname); alert(result.nickname); } }); </script>
其中遇到了兩個問題:
1、第一個問題:
Uncaught SyntaxError: Unexpected token :
解決方案如下:
This has just happened to me, and the reason was none of the reasons above. I was using the jQuery command getJSON and adding callback=? to use JSONP (as I needed to go cross-domain), and returning the JSON code {"foo":"bar"} and getting the error.
This is because I should have included the callback data, something like jQuery17209314005577471107_1335958194322({"foo":"bar"})
Here is the PHP code I used to achieve this, which degrades if JSON (without a callback) is used:
$ret['foo'] = "bar"; finish(); function finish() { header("content-type:application/json"); if ($_GET['callback']) { print $_GET['callback']."("; } print json_encode($GLOBALS['ret']); if ($_GET['callback']) { print ")"; } exit; }
