Python requests - POST data from a file
提问by user2190101
I have used curl to send POST requests with data from files.
我使用 curl 发送带有文件数据的 POST 请求。
I am trying to achieve the same using python requests module. Here is my python script
我正在尝试使用 python requests 模块实现相同的目标。这是我的python脚本
import requests
payload=open('data','rb').read()
r = requests.post('https://IP_ADDRESS/rest/rest/2', auth=('userid', 'password'), data=payload , verify=False)
print r.text
Data file looks like below
数据文件如下所示
'ID' : 'ISM03'
But my script is not POSTing the data from file. Am I missing something here.
但是我的脚本没有从文件中发布数据。我在这里遗漏了什么。
In Curl , I used to have a command like below
在 Curl 中，我曾经有一个像下面这样的命令
Curl --data @filename -ik -X POST 'https://IP_ADDRESS/rest/rest/2'

You do not need to use .read()here, simply stream the object directly. You do need to set the Content-Type header explicitly; curldoes this when using --databut requestsdoesn't:
.read()这里不需要使用，直接流式传输对象即可。您确实需要显式设置 Content-Type 标头；curl使用时执行此操作--data但requests不执行此操作：
with open('data','rb') as payload:
headers = {'content-type': 'application/x-www-form-urlencoded'}
r = requests.post('https://IP_ADDRESS/rest/rest/2', auth=('userid', 'password'),
data=payload, verify=False, headers=headers)
I've used the open file object as a context manager so that it is also auto-closed for you when the block exits (e.g. an exception occurs or requests.post()successfully returns).
我已经将打开的文件对象用作上下文管理器，以便在块退出时它也会自动关闭（例如发生异常或requests.post()成功返回）。
