jQuery:带有JSON的帖子实际上将发布数组

问题描述

我有一个Python作为CGI，来自jquery的POST会将json对象转换为数组，所以当我看到来自jquery的POST时，我实际上看到了:

login_user[username]=dfdsfdsf&login_user[password]=dsfsdf

([和]已转义)

我的问题是如何在python中将该字符串转换回JSON?或者，如何将这个字符串转换为python array/dict结构，以便我可以更轻松地处理它?

我的jquery正在发布:

{'login_user': {'username':username, 'password':password}}

解决方案

如果要完成的工作是从浏览器发送结构化数据，然后将其解压缩到Python后端并保持相同的结构，则建议以下操作:

1. 在浏览器中创建JavaScript对象来保存数据:

   var d = {}
   d['login_user'] = { 'username': 'foo', 'password': 'bar' }
   

2. 使用 https://github.com/douglascrockford/JSON-js 序列化为JSON

3. POST到您的后端，执行以下操作:

   $.post(URL，{'data':encode_json_data}，...)

4. 在您的Python代码中，解析JSON，在我的示例中，POST是在CGI脚本中获取POST数据的地方:

   data = json.loads(POST['data'])
   data['login_user']
   

I have a python as CGI and the POST from jquery will transform json object to array, so when I see the POST from jquery, I actually see:

login_user[username]=dfdsfdsf&login_user[password]=dsfsdf

(the [ and ] already escaped)

My question is how I can convert this string back to JSON in python? Or, how can I convert this string to python array/dict structure so that I can process it easier?

[edit]My jquery is posting:

{'login_user': {'username':username, 'password':password}}

解决方案

If what you want to accomplish is to send structured data from the browser and then unpack it in your Python backend and keep the same structure, I suggest the following:

1. Create JavaScript objects in the browser to hold your data:

   var d = {}
   d['login_user'] = { 'username': 'foo', 'password': 'bar' }
   

2. Serialize to JSON, with https://github.com/douglascrockford/JSON-js

3. POST to your backend doing something like this:

   $.post(url, {'data': encoded_json_data}, ...)

4. In your Python code, parse the JSON, POST in my example is where you get your POST data in your CGI script:

   data = json.loads(POST['data'])
   data['login_user']
