从Wikipedia检索数据并使用angularjs显示它

时间:2020-12-05 01:38:56

I am new to angularjs. I am trying to get data from wikipedia and show it in the front end. I retrived the data from wiki using the following php code

我是angularjs的新手。我试图从*获取数据并在前端显示它。我使用以下php代码从wiki中重新获取数据

$url = 'http://en.wikipedia.org/w/api.php?action=query&prop=extracts|info&exintro&titles=Sachin_Tendulkar&format=json&explaintext&redirects&inprop=url&indexpageids';
$json = file_get_contents($url);
echo json_encode($json);

following is my controller

以下是我的控制器

var demoApp = angular.module('demoApp',['ngRoute']);
demoApp.controller('SimpleController',function ($scope,$http){
    $http.post('server/view1.php').success(function(data){
        $scope.info = data;
    });
});

my html is as follows

我的HTML如下

<html ng-app="demoApp">
<head>
    <title> AngularJS Sample</title>
    <script type="text/javascript" src="js/angular.min.js"></script>
    <script type="text/javascript" src="js/angular-route.min.js"></script>
    <script type="text/javascript" src="js/script.js"></script>
    <link rel="stylesheet" type="text/css" href="css/style.css">
    <link rel="stylesheet" type="text/css" href="css/bootstrap-combined.min.css">
</head>
<body>
    <div ng-controller="SimpleController">
        {{info.query}} // I dont know if this is right
    </div>
</body>
</html>

I want to display all the content that is retrieved in the front end but it is not showing up. I dont know what I have done wrong. I am a newbie to angularjs.

我想显示在前端检索但未显示的所有内容。我不知道我做错了什么。我是angularjs的新手。

Skip the PHP Part and use Angular JSONP with the following parameter:

跳过PHP部件并使用带有以下参数的Angular JSONP:

format=json
callback=JSON_CALLBACK

So Angular can understand and parse the Wiki Answer:

所以Angular可以理解和解析Wiki答案:

$http({
    url: 'http://de.wikipedia.org/w/api.php?action=query&list=random&rnlimit=1&rawcontinue&format=json&callback=JSON_CALLBACK',
    method: 'jsonp'
}).success(function(response) {
    console.log(response);
    $scope.response = response;
});

This works also with action=parse to get an article.

这也适用于action = parse来获取文章。

If you want to display the raw json response on the page, use the json filter:

如果要在页面上显示原始json响应,请使用json过滤器:

<pre>{{ response | json }}</pre>

With the given URL, you get a JSON-formatted response. Why do you encoding a JSON respons to JSON? That's not needed, so skip that part.

使用给定的URL,您将获得JSON格式的响应。为什么要编写JSON响应JSON?这不是必需的,所以跳过那一部分。

<?php
$url ='http://en.wikipedia.org/w/api.php?action=query&prop=extracts|info&exintro&titles=Sachin_Tendulkar&format=json&explaintext&redirects&inprop=url&indexpageids';
$json = file_get_contents($url);
echo json;
?>

Just open the url, you can see the reponse.

只需打开网址,即可看到响应。

In your example, your php code is pretty useless. Maybe you can use the API directly in your controller:

在你的例子中,你的PHP代码是没用的。也许您可以直接在控制器中使用API​​:

$http.get('http://en.wikipedia.org/w/api.php?[....]').success(function(data){
    $scope.info = data;
});
