[英]is there a difference between curl -u and python requests
因此,有一个我想使用python.Requests
检索的python.Requests
https://ororo.tv/api/v2/episodes/9
需要基本身份验证。 如果我像这样卷曲
curl -u test@example.com:password https://ororo.tv/api/v2/episodes/9
但是,当尝试使用Requests
库在python中执行相同操作时,我得到了想要的响应,像这样
>>> r = requests.get('https://ororo.tv/api/v2/episodes/9', auth=('test@example.com', 'password'))
>>> r
<Response [520]>
我总是得到520响应。 有人可以告诉我,我可能做错了什么?
是的,有细微的差别。 发送的标头中存在细微的差异,这些差异显然与此API有关。
如果更改查询使用http://httpbin.org/get
的URL(在线HTTP测试服务HTTPBin.org的端点) ,则可以看到curl
和requests
发送内容的不同:
$ curl -u test@example.com:password http://httpbin.org/get
{
"args": {},
"headers": {
"Accept": "*/*",
"Authorization": "Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==",
"Host": "httpbin.org",
"User-Agent": "curl/7.51.0"
},
"origin": "84.92.98.170",
"url": "http://httpbin.org/get"
}
$ python -c "import requests; print(requests.get('http://httpbin.org/get', auth=('test@example.com', 'password')).text)"
{
"args": {},
"headers": {
"Accept": "*/*",
"Accept-Encoding": "gzip, deflate",
"Authorization": "Basic dGVzdEBleGFtcGxlLmNvbTpwYXNzd29yZA==",
"Host": "httpbin.org",
"User-Agent": "python-requests/2.11.1"
},
"origin": "84.92.98.170",
"url": "http://httpbin.org/get"
}
要突出区别:
requests
发送一个额外的标头Accept-Encoding
,设置为gzip, deflate
User-Agent
标头有所不同; 两者都反映了当前的代理商。 您必须在https://ororo.tv/api/v2
网站上查看这些标题中的哪一个导致了该问题。 当我更正URL以使用v2
和https
(例如curl
命令) 并设置User-Agent
标头时,我得到一个有效的响应:
>>> headers = {'User-Agent': 'curl/7.51.0'}
>>> r = requests.get('https://ororo.tv/api/v1/episodes/9',
auth=('test@example.com', 'password'), headers=headers)
>>> r
<Response [200]>
>>> from pprint import pprint
>>> pprint(r.json())

当使用类似Python的请求时,您尝试使用的api可能要求您以特定的方式格式化请求,可能需要标头和base64编码的身份验证。
看看这个例子,它将向您展示如何同时发送base64编码的身份验证标头和一些数据:
import requests
import base64
username = "some_username"
password = "some_password"
request_url = "https://ororo.tv/api/v2/episodes/9"
# In this example, I'm passing some data along with the request.
# these are generally what you would expect to pass along in an encoded url:
# /api?some_url_param_key=some_url_param_value
data = {}
data["some_url_param_key"] = "some_url_param_value"
# This is an example header, not necessarily what you need,
# but it should serve as a good starting point.
headers = {}
headers["Authorization"] = "Basic " + base64.encodestring(username + ":" + password).replace('\n', '')
headers["Accept"] = "*/*"
headers["Content-Type"] = "application/x-www-form-urlencoded"
headers["User-Agent"] = "runscope/0.1"
# You can use post() in some cases where you would expect to use get().
# Every API is its own unique snowflake and expects different inputs.
# Try opening up the Chrome console and run the request in the
# browser, where you know it works. Examine the headers and response
# in cases where the API you're accessing doesn't provide you
# with the necessary inputs.
result = requests.post(request_url, headers=headers, data=data)
print result
