How do I read a response from Python Requests?
提问by Oli
I have two Python scripts. One uses the Urllib2 libraryand one uses the Requests library.
我有两个 Python 脚本。一种使用Urllib2 库，一种使用Requests 库。
I have found Requests easier to implement, but I can't find an equivalent for urlib2's read()function. For example:
我发现 Requests 更容易实现，但我找不到 urlib2read()函数的等效项。例如：
...
response = url.urlopen(req)
print response.geturl()
print response.getcode()
data = response.read()
print data
Once I have built up my post url, data = response.read()gives me the content - I am trying to connect to a vcloud director api instance and the response shows the endpoints that I have access to. However if I use the Requests library as follows.....
一旦我建立了我的帖子 url，data = response.read()给我内容 - 我正在尝试连接到 vcloud Director api 实例，响应显示我有权访问的端点。但是，如果我使用 Requests 库如下.....
....
def post_call(username, org, password, key, secret):
endpoint = '<URL ENDPOINT>'
post_url = endpoint + 'sessions'
get_url = endpoint + 'org'
headers = {'Accept':'application/*+xml;version=5.1', \
'Authorization':'Basic '+ base64.b64encode(username + "@" + org + ":" + password), \
'x-id-sec':base64.b64encode(key + ":" + secret)}
print headers
post_call = requests.post(post_url, data=None, headers = headers)
print post_call, "POST call"
print post_call.text, "TEXT"
print post_call.content, "CONTENT"
post_call.status_code, "STATUS CODE"
....
....the print post_call.textand print post_call.contentreturns nothing, even though the status code equals 200 in the requests post call.
....theprint post_call.text并print post_call.content没有返回任何内容，即使状态代码在调用后的请求中等于 200。
Why isn't my response from Requests returning any text or content?
为什么我的请求响应没有返回任何文本或内容？

Requests doesn't have an equivalent to Urlib2's read().
Requests 没有相当于 Urlib2 的read().
>>> import requests
>>> response = requests.get("http://www.google.com")
>>> print response.content
'<!doctype html><html itemscope="" itemtype="http://schema.org/WebPage"><head>....'
>>> print response.content == response.text
True
It looks like the POST request you are making is returning no content. Which is often the case with a POST request. Perhaps it set a cookie? The status code is telling you that the POST succeeded after all.
看起来您发出的 POST 请求没有返回任何内容。POST 请求通常就是这种情况。也许它设置了一个cookie？状态代码告诉您 POST 最终成功了。

If the response is in json you could do something like (python3):
如果响应在 json 中，您可以执行类似 (python3) 的操作：
import json
import requests as reqs
# Make the HTTP request.
response = reqs.get('http://demo.ckan.org/api/3/action/group_list')
# Use the json module to load CKAN's response into a dictionary.
response_dict = json.loads(response.text)
for i in response_dict:
print("key: ", i, "val: ", response_dict[i])
To see everything in the response you can use .__dict__:
要查看响应中的所有内容，您可以使用.__dict__：
print(response.__dict__)
