使用 Angular.js 的 HTTP POST [英] HTTP POST using Angular.js

问题描述

我是这个场景的新手，我想使用 Angular.js 发出 HTTP POST 请求.我正在访问 PHP 脚本，这些脚本的参数只是 POST 变量.每个脚本返回的是一个 JSON 字符串.通常在 HTML 表单中，您可以发出这样的请求:

I'm new to the scene and I want to use Angular.js to make an HTTP POST request. I'm accessing PHP scripts which have parameters that are just POST variables. What gets returned from each script is a JSON string. Normally in an HTML form you can make such a request like:

<form method="post" action="url.php">
<input name="this">
<input name="that">
<input value="Submit">
</form>

根据您的输入和点击提交后，JSON data1 将返回如下内容:{ "code" : 1 }

Depending on your input and after you click submit, JSON data1 will return something like this: { "code" : 1 }

我无法访问脚本或托管它们的服务器.

I have no access to the scripts or to the servers that hosts them.

我想知道 Angular.js 是否可以读取 JSON 数据 1，将该数据 1 与它们在我的 JSON 数据 2 中定义的内容相匹配，然后将它们输出到我的视图中 (<pre>data2</pre>).

I was wondering if it's possible for Angular.js to read the JSON data1, match that data1 to what they're defined in my JSON data2, and then output them to my view (<pre>data2</pre>).

例如，如果检索到 { "code" : 1 }，我希望我的 JSON 输出代码 #1 的值:

For example, if { "code" : 1 } is retrieved, I want my JSON to output the value for code #1:

{ "code" : [
  { 1: "User already logged in." }, 
  { 2: "Wrong parameters, try again."}, 
  { 3: "etc., etc." }
 ] 
};

这是我的尝试:

<form ng-controller="PhpCtrl" name="f1">
<input type="text" name="name">
<input type="text" name="password">
<pre ng-model="codeStatus">{{codeStatus}}</pre>
<input type="submit" ng-click="add()" value="Submit">
</form>

function PhpCtrl($scope, $http, $templateCache) {
    $scope.method = 'POST';
    $scope.url = 'url.php';
    $scope.codeStatus = "";

    $scope.add = function() {

        $http({
            method: $scope.method, 
            url: $scope.url,
            headers: {'Content-Type': 'application/x-www-form-urlencoded'},  
            cache: $templateCache
        }).
        success(function(response) {
            $scope.codeStatus = response.data;
        }).
        error(function(response) {
            $scope.codeStatus = response || "Request failed";
        });
        return false;   
    };
}

到目前为止，它在视图中发布的所有内容都是请求失败"，哈哈，虽然它正在处理 HTTP/1.1 200.我知道我还有很长的路要走，但我会很感激任何帮助.一旦我弄清楚如何将正确的 JSON 数据 1 发布到视图，下一步就是匹配和输出适当的数据 2.提前致谢！

All it's posting so far to the view is "Request failed" lol, although it's processing HTTP/1.1 200. I know I still have a ways to go but I would appreciate any help. Once I figure out how to post the proper JSON data1 to the view, the next step is matching and outputting the appropriate data2. Thank you in advance!

推荐答案

实际上问题出在 PHP 后端，您没有像往常一样检索发布的数据，这对我有用:

Acctually the problem is in the backend with PHP you don't retrieve the posted data like usual, this worked for me:

function PhpCtrl($scope, $http, $templateCache) {
  var method = 'POST';
  var url = 'url.php';
  $scope.codeStatus = "";
  $scope.add = function() {
    var FormData = {
      'name' : document.f1.name.value,
      'password' : document.f1.password.value
    };
    $http({
      method: method,
      url: url,
      data: FormData,
      headers: {'Content-Type': 'application/x-www-form-urlencoded'},
      cache: $templateCache
    }).
    success(function(response) {
        $scope.codeStatus = response.data;
    }).
    error(function(response) {
        $scope.codeStatus = response || "Request failed";
    });
    return false;
  };
}

在 PHP 文件中:

$data = json_decode(file_get_contents("php://input"));
echo $data->name;
