Python'str'对象没有属性'read' [英] Python 'str' object has no attribute 'read'

问题描述

Python 3.3.2 import json& urllib.request

Python 3.3.2 import json & urllib.request

Json

[{"link":"www.google.com","orderid":"100000222"},
{"link":"www.google.com","orderid":"100000222"},
{"link":"www.google.com","orderid":"100000222"}]

print(response.info())

print(response.info())

Date: Sun, 20 Oct 2013 07:06:51 GMT
Server: Apache
X-Powered-By: PHP/5.4.12
Content-Length: 145
Connection: close
Content-Type: application/json

代码

url = "http://www.Link.com"
    request = urllib.request.Request(url)
    request.add_header('User-Agent','Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)')
    request.add_header('Content-Type','application/json')
    response = urllib.request.urlopen(request)

    decodedRes = response.read().decode('utf-8')
    json_object = json.load(decodedRes)

以下是我的代码 错误

Traceback (most recent call last):
  File "C:\Users\Jonathan\Desktop\python.py", line 57, in <module>
    checkLink()
  File "C:\Users\Jonathan\Desktop\python.py", line 50, in checkLink
    json_object = json.load(decodedRes)
  File "C:\Python33\lib\json\__init__.py", line 271, in load
    return loads(fp.read(),
AttributeError: 'str' object has no attribute 'read'
>>> .

有什么主意我可以解决这个问题吗?

Any idea how i can fix this issue?

推荐答案

使用 json.loads 而不是json.load.

json.loads(decodedRes)

• json.load 接受类似文件的对象.

>>> import json
>>> json.load('{"a": 1}')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\json\__init__.py", line 286, in load
    return loads(fp.read(),
AttributeError: 'str' object has no attribute 'read'
>>> json.loads('{"a": 1}')
{u'a': 1}

或者，您可以将响应对象传递给json.load:

## decodedRes = response.read().decode('utf-8')
json_object = json.load(response)
