在Web App中使用PHP和AngularJs的mysql数据库。
控制台没有抛出任何错误。我使用ng-model
将desc
,pric
,cat
和title
双重绑定到html中的输入标记。这是我的javascript:
app.controller('MainController', ['$scope', '$http', function($scope, $http) {
$scope.light = "Light";
var _userId = 44;
$scope.desc = "" ;
$scope.pric = "" ;
$scope.cat = "";
$scope.title = "HERE I AM!";
$scope.sendPost = function() {
var data = $.param({
json: JSON.stringify({
userId: _userId,
price: $scope.pric,
description: $scope.desc,
category: $scope.cat,
postTitle: $scope.title,
photo1: "",
photo2: "",
photo3: "",
tag1: "",
tag2: "",
tag3: ""
})
});
$http.post("http://speffs.one/SPE/post.php", data).success(function(data, status) {
window.alert("HIII I AM IN");
});
};
}]);
所有内容都在编译/显示,但是当我从数据库中检索时,它并没有向数据库发布任何内容。成功警报" HI I AM IN"也正在执行。
这是PHP:
<?php
//header('Access-Control-Allow-Origin: *');
//require_once 'https://filemanager.one.com/#aamirz@princeton.edu/speffs.one/files/SPE/connect.php';

//$string = json_decode($jsonInput);
//$file = fopen("testing.txt", "w");
//$myfile = fopen("testfile.txt", "w");
//var_dump($_POST);

}

} else {

}

$stmt->execute() ;
$stmt->close();
$conn->close();
} catch (PDOException $pe) {

}
?>
我们已经使用带有JSON的Android平台上的PHP,它已经有效,它只是不适用于我们的有角度的网络应用程序。救命!谢谢! &lt; 3

您的代码中的一个问题是您尝试使用close() - 函数关闭PDO连接,这是不允许的。您应该将$ conn变量设置为null。请参阅此帖子:PDO closing connection。
您可以通过将此添加到您的帖子请求中来查看php代码中的错误:
$http.post("http://speffs.one/SPE/post.php", $scope.data).success(function(data, status) {
console.log("Data: "+data+" Status: "+status);
window.alert("HIII I AM IN");
});
然后它将在您的Web浏览器控制台中打印错误。运行代码时出现此错误:致命错误:调用未定义的方法PDOStatement :: close()in ...
当我从使用close() - 函数更改为将PDO连接设置为null时,您的代码适用于我(我一直在使用简单的虚拟数据),来自前端的数据将发布到数据库中。尝试在帖子请求函数中添加“console.log”,看看是否有任何错误可能会给你一些问题提示。

在不知道任何错误消息或异常的情况下,我怀疑您遇到了CORS问题,您是否在http://speffs.one/SPE/post.php的响应中指定了Access-Control-Allow-Origin
标头?
也不是你应该使用CORS预检POST / PUT / DELETE
请参阅: https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS#Preflighted_requests
当您使用cURL或任何其他HTTP库时,您不需要CORS,但如果您从浏览器发出请求,则需要它!
