你可以通过一个URL发送JSON？ [英] Can you send JSON through a url?

问题描述

我有一个Ruby散列，其中键是URL和值是整数。我转换哈希JSON和我想知道如果我将能够通过Ajax请求发送JSON一个URL里面，然后拉了JSON从params散列，。

I have a ruby hash where the keys are urls and the values are integers. I convert the hash to JSON and I'm wondering if I'll be able to send the JSON inside a url via an AJAX request and then pull that JSON from a params hash.

此外，我将要发送JSONifyed红宝石哈希返回给客户端。如果我有一个成功的回调在我的AJAX功能，我接收到的数据在数据变量，我怎么解析JSON与jQuery？

Also, I am going to be sending a JSONifyed ruby hash back to the client. If I have a success callback in my AJAX function where I receive the data in a data variable, how do I parse that JSON with JQuery?

请让我知道如果我需要更加具体。

Please let me know if I need to be more specific.

推荐答案

是的，你可以没有问题。无需手动编码/解码需要！

Yes, you can with no problem. No manual encoding/decoding needed!

您code会是这样的：

Your code would be like this:

var jsonParam = '{"name":"Edgar"}'; //Sample json param
$.ajax({
  ...  
  type: "get", //This sends in url
  data: {jsonParam: jsonParam}, //This will encode your json for url automatically
  dataType: "json", //With this the response will be automatically json-decoded!
  success: function(response){ //Assuming your server output was '{"lastName":"Villegas"}' as string
     alert(response.lastName);
  }
});

正如你所看到的，是不需要手动编码/解码。 jQuery的处理这一切！

As you can see, no manual encoding/decoding was needed. Jquery handles it all!

希望这有助于。干杯

PS：如果由于某种原因，你需要连接C本JSON code /德$ C $手动为URL中使用JavaScript的连接codeURIComponent（字符串）和 $。parseJSON（jsonString）的方法。

PS: If, for some reason, you need to encode/decode your json manually for url use javascript's encodeURIComponent(string) and $.parseJSON(jsonString) methods.
