Python通过json.loads dict到JSON：

I have troubleshooting some code that uses HTTP POST to send data and should return a JSON result whose contents are a dictionary. I am using an XML-RPC wrapper to expose this service. When the wrapper receives the dict information from the http response variable, the dict contents are in a string in this form:

我已经对使用HTTP POST发送数据的一些代码进行了故障排除，并且应该返回其内容为字典的JSON结果。我正在使用XML-RPC包装器来公开此服务。当包装器从http响应变量接收到dict信息时，dict内容以这种形式包含在字符串中：

{'created': datetime.datetime(2010, 12, 31, 19, 13, 8, 379909), 'worker': u'GoogleWorker', 'ready': False, 'request_id': '8f1381853a444a42a37ae5152a3af947', 'owner': u'admin', 'shortname': u'test19'}

I'm trying to convert the string below into a JSON result using the following statement:

我正在尝试使用以下语句将下面的字符串转换为JSON结果：

result = json.loads(response[1])

However, when I try to use json.loads to convert the data to JSON, I get the following error: Fault: <Fault 1: "<type 'exceptions.ValueError'>:Expecting property name: line 1 column 1 (char 1)">

但是，当我尝试使用json.loads将数据转换为JSON时，我收到以下错误：Fault：：Expecting property name：line 1 column 1（char 1 ）“>

I manually tried to convert the above string to JSON, but I get the same error. Is the dict malformed in some way? Is it due to unicode? I also tried setting the locale to UTF-8, but that was unsuccessful.

我手动尝试将上面的字符串转换为JSON，但我得到了同样的错误。这个词典在某种程度上是不正确的吗？是unicode吗？我也尝试将语言环境设置为UTF-8，但这不成功。

Any help would be greatly appreciated.

任何帮助将不胜感激。

You are trying to use the wrong method. json.loads is for loading JSON to Python. If you want to convert Python to JSON, you need json.dumps.

您正在尝试使用错误的方法。 json.loads用于将JSON加载到Python。如果要将Python转换为JSON，则需要json.dumps。

result = json.dumps(response[1])

#2

That dict is in Python dict literal format, not JSON. You can do:

该dict采用Python dict文字格式，而不是JSON。你可以做：

import ast
result = ast.literal_eval(response[1])

to read in the response in that format. Are you sure that Django hasn't already JSON-decoded the response?

以该格式读取响应。你确定Django还没有JSON解码响应吗？

i have use json on django , i use this :

我在django上使用json，我使用这个：

import simplejson as json
#to encode
final= {'first':first_data,'second':second_data}
json.dumps(final)
#to decode this is the example from python's api 
json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]')
