将json字符串转换为python对象 [英] convert a json string to python object

问题描述

是否可以将json字符串(例如，从twitter搜索json服务返回的json字符串)转换为简单的字符串对象.这是从json服务返回的数据的一小幅表示形式:

Is it possible to convert a json string (for e.g. the one returned from the twitter search json service) to simple string objects. Here is a small representation of data returned from the json service:

{
results:[...],
"max_id":1346534,
"since_id":0,
"refresh_url":"?since_id=26202877001&q=twitter",
.
.
.
}

让我们说我以某种方式将结果存储在某个变量中，例如 obj .我正在寻找适当的值，如下所示:

Lets say that I somehow store the result in some variable, say, obj. I am looking to get appropriate values like as follows:

print obj.max_id
print obj.since_id

我尝试使用simplejson.load()和json.load()，但是它给我一个错误，提示'str' object has no attribute 'read'

I've tried using simplejson.load() and json.load() but it gave me an error saying 'str' object has no attribute 'read'

推荐答案

我尝试使用simplejson.load()和json.load()，但是它给我一个错误，提示'str' object has no attribute 'read'

I've tried using simplejson.load() and json.load() but it gave me an error saying 'str' object has no attribute 'read'

要从字符串加载，请使用json.loads()(请注意's').

To load from a string, use json.loads() (note the 's').

更有效地，跳过将响应读取为字符串的步骤，只需将响应传递给json.load().

More efficiently, skip the step of reading the response into a string, and just pass the response to json.load().
