我剛剛創建了一個離子應用程序,它只有一個註冊頁面。我正在做的是在後端使用php RESTful Web服務,MySql是數據庫。但我得到這個錯誤:「SyntaxError:意外的令牌<」。我不知道如何解決這個錯誤。請指導我解決這種類型的錯誤。SyntaxError:Unexpected token <at Object.parse(native)
我的index.html是:
<ion-content class="has-header" ng-controller="SignupCtrl">
<div class="list list-inset">
<label class="item item-input">
<input class="form-control" type="text" ng-model="userdata.username" placeholder="Enter Username">
</label>
<label class="item item-input">
<input type="text" ng-model="userdata.email" placeholder="Enter Your Email">
</label>
<label class="item item-input">
<input class="form-control" type="password" ng-model="userdata.password" placeholder="Enter Your Password">
</label>
<button class="button button-block button-positive" ng-click="signup(userdata)">SignUp</button><br>
<span>{{responseMessage}}</span>
</div>
</ion-content>
我的控制器代碼是:
.controller('SignupCtrl', function($scope, $http) {
$scope.signup = function (userdata) {
var request = $http({
method: "POST",
url: "http://localhost/lastLog.php",
crossDomain : true,
data: {
email: userdata.email,
password: userdata.password,
username: userdata.username
},
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
});
/* Successful HTTP post request or not */
request.success(function(data) {
if(data == "1"){
$scope.responseMessage = "Successfully Created Account";
}
if(data == "2"){
$scope.responseMessage = "Create Account failed";
}
else if(data == "0") {
$scope.responseMessage = "Email Already Exist"
}
});
}
})
我的PHP代碼:
<?php
header("Content-Type: application/json; charset=UTF-8");
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: GET, POST');
$postdata = file_get_contents("php://input");
$request = json_decode($postdata);
$email = $postdata->email;
$password = $postdata->password;
$username = $postdata->username;
$con = mysql_connect("localhost","root",'') or die ("Could not connect: " . mysql_error());;
mysql_select_db('db_lastLog', $con);
$qry_em = 'select count(*) as cnt from users where email ="' . $email . '"';
$qry_res = mysql_query($qry_em);
$res = mysql_fetch_assoc($qry_res);
if($res['cnt']==0){
$qry = 'INSERT INTO users (name,pass,email) values ("' . $username . '","' . $password . '","' . $email . '")';
$qry_res = mysql_query($qry);
if ($qry_res) {
echo "1";
} else {
echo "2";;
}
}
else
{
echo "0";
}
?>
難道你有你的錯誤行號? –
它說:「在fromJson(http:// localhost:8100/lib/ionic/js/ionic.bundle.js:14543:14)」 –
php腳本在服務器端執行。 –
