蟒蛇 - ValueError错误：需要比1的值更解压 [英] Python - ValueError: need more than 1 value to unpack

问题描述

请检查这个问题的Python的oauth2 - 使申请我与VIMEO整合工作的我Web应用程序。

起初，我得到了一个 oauth_signature ，我没有任何问题（没有错误），我想这些事情再一次从第一，现在我得到的 ValueError错误：需要多个值解压，而提出这个要求。

 ＆GT;＆GT;＆GT; R = request.GET中（URL，标题=标题）

该错误是

 回溯（最后最近一次调用）：
文件＆LT;＆控制台GT;，1号线，上述＆lt;＆模块GT;
文件/usr/local/lib/python2.7/dist-packages/requests-0.10.1-py2.7.egg/requests/api.py51行，在GET

在历数（头）我，（值，则params）：
ValueError错误：需要超过1的数值来解压
 

谢谢！

更新

 ＆GT;＆GT;＆GT;头
{'授权'： u'oauth_body_hash=XXXXXXXXXXXXXXXXXXXXXXXXXX,oauth_nonce=3454768,oauth_timestamp=1340035585,oauth_consumer_key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,oauth_signature_method=HMAC-SHA1,oauth_version=1.0,oauth_signature=XXXXXXXXXXXXXXXXXXXXXXXXXXXXX,oauth_callback=http://127.0.0.1:8000/information/vimeo'}
 

解决方案

要能够解开字典你将不得不使用.items（），所以code会是这样的：

 对于我，（值，则params）在枚举（headers.items（））：
 

现在因为这是不是你的code和你不能改变它，有什么错误是告诉你的是，标题不应该是一个字典，而是一元组（或清单），如果传递的头像这样的：

 标题= [（授权，值）]
 

它应该工作。

编辑：这不作品。现在，词典版本{授权：值}。为我工作，也许更新请求帮助

Please check this question Python oauth2 - making request I am working with vimeo integration in my web application.

Initially I got an oauth_signature and I had no problems(no errors), I tried those things once again from the first and Now I'm getting ValueError: need more than 1 value to unpack while making this request

>>> r = request.get(url, headers=headers)

You can check out my code here https://gist.github.com/2949182

The error is

Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/requests-0.10.1-py2.7.egg/requests/api.py", line 51, in get
return request('get', url, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests-0.10.1-py2.7.egg/requests/api.py", line 39, in request
return s.request(method=method, url=url, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/requests-0.10.1-py2.7.egg/requests/sessions.py", line 159, in request

for i, (value, params) in enumerate(headers):
ValueError: need more than 1 value to unpack

Thanks!

UPDATE

>>> headers
{'Authorization': u'oauth_body_hash=XXXXXXXXXXXXXXXXXXXXXXXXXX,oauth_nonce=3454768,oauth_timestamp=1340035585,oauth_consumer_key=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX,oauth_signature_method=HMAC-SHA1,oauth_version=1.0,oauth_signature=XXXXXXXXXXXXXXXXXXXXXXXXXXXXX,oauth_callback=http://127.0.0.1:8000/information/vimeo'}

解决方案

to be able to unpack a dictionary you would have to use the .items(), so the code would be like this:

for i, (value, params) in enumerate(headers.items()):

now since that is not your code and you can't change it, what the error is telling you is that the headers should not be a dictionary but a tuple (or a list), if you pass the header like this:

headers = [("Authorization", "Values")]

it should work.

EDIT: This doesn't works. Now the dictionary version {"Authorization": "Values"} works for me, maybe updating requests will help.
