Question

我有Python 3，我试图通过API link to API documentation发布到Tumblr。尽管感觉我正在做正确的事情，但我仍然收到错误401。 Python 2中有一个官方的API客户端，但感觉有点难以理解，所有其他提到的似乎都是PHP或Java。我也不确定在401错误之后发布的格式，因为文档没有提供除/ post之外的任何明确示例。我的代码：

import requests
from requests_oauthlib import OAuth1
#variables for later
client_key=""
client_secret=""
oauth_token=""
oauth_token_secret=""

#gets the values for the variables
with open("API.txt", 'r') as readAPI:
    readAPI.readline()
    client_key=readAPI.readline()[23:]
    client_secret=readAPI.readline()[23:]
    oauth_token=readAPI.readline()[23:]
    oauth_token_secret=readAPI.readline()[23:]
readAPI.close()

#prints them to double check they are being read correctly
print(client_key)
print(client_secret)
print(oauth_token)
print(oauth_token_secret)

#sets oauth for the connection
oauth = OAuth1(client_key,
               client_secret,
               oauth_token,
               oauth_token_secret)

#check post that should return various blog stats
r = requests.get("http://api.tumblr.com/v2/user/info" ,auth=oauth)

print(r)

我100％确定我获取客户端密钥，客户端密钥，oauth令牌和oauth令牌密钥正确。我进行了双重检查，oauth令牌都放在手动读取的文件中，并在连接尝试之前打印。我100％确定它是正确的。我想知道Tumblr的API是否被破坏了？

编辑：这是打印（repr（））

'client_key'
'client_secret'
'oauth_token'
'oauth_token_secret'
{"meta":{"status":401,"msg":"Not Authorized"},"response":[]}

这是在尝试新代码和使用带有JSON的Steven方法后发生的事情。

b'{"meta":{"status":401,"msg":"Not Authorized"},"response":[]}'

Answer 1

而不是这样做：

print(client_key)

这是什么输出？

print(repr(client_key))

您正在使用readline，其中包含每行末尾的换行符：

$ cat foo.txt
key
secret
blabla

$ python3.4
>>> f = open("foo.txt")
>>> print(repr(f.readline()))
'key\n'
>>> print(repr(f.readline()))
'secret\n'
>>> print(repr(f.readline()))
'blabla\n'

您是否尝试过删除每行的换行符？

修改：根据@ user2853325的评论更新我的帖子。您的代码适用于Python 3.4，requests == 2.5.2和requests-oauthlib == 0.4.2。

API.json（编辑密钥/秘密）：

{
    "client_key": "XXXXXXXXXXXXXXXXXXXXdG7zXIMcDidwQ5pMHuQTbxyhNINrCE",
    "client_secret": "XXXXXXXXXXXXXXXXXXXX72A5HQO1axydP5nlOWCTQx4ECfXfyX",
    "oauth_token": "XXXXXXXXXXXXXXXXXXXX8WAnqMBWaAdnGhnc4gWhJ4j6cufK1W",
    "oauth_token_secret": "XXXXXXXXXXXXXXXXXXXX8Kf82k65JzIcMU7QUp54ssPEzJd7my"
}

tumblr.py：

import json

import requests
from requests_oauthlib import OAuth1

#gets the values for the variables
with open("API.json") as f:
    credentials = json.load(f)

#prints them to double check they are being read correctly
print(credentials)

#sets oauth for the connection
oauth = OAuth1(
    credentials['client_key'],
    credentials['client_secret'],
    credentials['oauth_token'],
    credentials['oauth_token_secret']
)

#check post that should return various blog stats
r = requests.get("http://api.tumblr.com/v2/user/info", auth=oauth)
print(r)
print(r.content)

输出（编辑oauth东西）：

$ bin/python tumblr.py
{'oauth_token_secret': 'XXXXXXXXXXXXXXXXXXXX8Kf82k65JzIcMU7QUp54ssPEzJd7my', 'client_secret': 'XXXXXXXXXXXXXXXXXXXX72A5HQO1axydP5nlOWCTQx4ECfXfyX', 'client_key': 'XXXXXXXXXXXXXXXXXXXXdG7zXIMcDidwQ5pMHuQTbxyhNINrCE', 'oauth_token': 'XXXXXXXXXXXXXXXXXXXX8WAnqMBWaAdnGhnc4gWhJ4j6cufK1W'}

所以现在我已经为自己测试了你的代码：

您是如何获得oauth_token和oauth_token_secret的？我点击了＃34;探索API＆＃34;在Applications developer page上。
您不需要致电readAPI.close()，因为with屏幕会自动为您关闭文件（请参阅official docs）。
我使用JSON存储和阅读凭据，这样我就100％确定我获得了正确的字符串。代码也更清晰。我仍然怀疑你从文件中读取行并切片的方式。
尝试以与我相同的方式在代码中打印r.content。它是否为您提供了比＃34; 401 Unauthorized＆＃34;？

Python 3请求尝试使用Tumblr API，我得到错误401？
