我如何获得API请求到我的网页的JavaScript的JSON？ [英] How do I get the JSON from an API request into my page's javascript?

问题描述

我试图使用Web API，JavaScript中返回一个JSON文件。使用炼金术API，调用将以下网址：

<$p$p><$c$c>http://access.alchemyapi.com/calls/url/URLGetTextSentiment?url=http%3A%2F%2Fwww.macrumors.com%2F2013%2F11%2F05%2Fapple-releases-itunes-11-1-3-with-equalizer-and-performance-improvements%2F&apikey=[secret]&outputMode=json

这将运行在一个加拿大家园文章情感分析。不过，我不确定如何真正得到JSON文件转换为JavaScript。有谁知道怎么样？

解决方案

您正在访问自然会返回JSON，所以使用一个Ajax GET 请求网址

使用 jQuery.get（）：

  VAR URL = 'http://access.alchemyapi.com/calls/url/URLGetTextSentiment?url=http%3A%2F%2Fwww.macrumors.com%2F2013%2F11%2F05%2Fapple-releases-itunes-11-1-3-with-equalizer-and-performance-improvements%2F&apikey=[secret]&outputMode=json'
$获得（
  网址，
  功能（数据，状态XHR）{
    警报（数据）;
  }
）;
 

I'm trying to use a web api to return a JSON file in JavaScript. Using the Alchemy API, the call would be to the following URL:

http://access.alchemyapi.com/calls/url/URLGetTextSentiment?url=http%3A%2F%2Fwww.macrumors.com%2F2013%2F11%2F05%2Fapple-releases-itunes-11-1-3-with-equalizer-and-performance-improvements%2F&apikey=[secret]&outputMode=json

This would run sentiment analysis on a macrumors article. However, I am unsure as to how to actually get the JSON file into javascript. Does anybody know how?

解决方案

The URL you're accessing appears to return JSON, so use an ajax get request

With jQuery.get():

var Url = 'http://access.alchemyapi.com/calls/url/URLGetTextSentiment?url=http%3A%2F%2Fwww.macrumors.com%2F2013%2F11%2F05%2Fapple-releases-itunes-11-1-3-with-equalizer-and-performance-improvements%2F&apikey=[secret]&outputMode=json'


$.get(
  Url,
  function(data, status, xhr){
    alert(data);
  }
);
