PUT Request to REST API using Python
提问by Tim
For some reason my put request is not working and I am getting syntax errors. I am new to Python but I have my GET and POST requests working. Does anyone see anything wrong with this request and any recommendations? I am trying to change the description to "Changed Description"
出于某种原因，我的 put 请求不起作用，并且出现语法错误。我是 Python 新手，但我的 GET 和 POST 请求可以正常工作。有没有人看到这个请求和任何建议有什么问题？我正在尝试将描述更改为“已更改的描述”
PUT
放
#import requests library for making REST calls
import requests
import json
#specify url
url = 'my URL'
token = "my token"
data = {
"agentName": "myAgentName",
"agentId": "20",
"description": "Changed Description",
"platform": "Windows"
}
headers = {'Authorization': 'Bearer ' + token, "Content-Type": "application/json", data:data}
#Call REST API
response = requests.put(url, data=data, headers=headers)
#Print Response
print(response.text)
Here is the error I am getting.
这是我得到的错误。
Traceback (most recent call last):
line 17, in <module>
headers = {'Authorization': 'Bearer ' + token, "Content-Type": "application/json", data:data}
TypeError: unhashable type: 'dict'

Syntax error in because of =sign in your headersdictionary:
由于=在您的headers字典中签名导致语法错误：
headers = {'Authorization': 'Bearer ' + token, "Content-Type": "application/json", data=data}
It should be:
它应该是：
headers = {'Authorization': 'Bearer ' + token, "Content-Type": "application/json", 'data':data}
See data=datais changed with 'data':data. Colon and Single Quotes.
见data=data与'data':data。冒号和单引号。
And are you sure you will be sending data in your headers? Or you should replace your payloadwith datain your putrequest?
您确定要在标头中发送数据吗？或者你应该更换你payload与data你的put要求吗？
Edit:
编辑：
As you have edited the question and now you are sending data as PUT request's body requests.put(data=data)so there is no need of it in headers. Just change your headers to:
由于您已经编辑了问题，现在您将数据作为 PUT 请求的正文发送requests.put(data=data)，因此标题中不需要它。只需将您的标题更改为：
headers = {'Authorization': 'Bearer ' + token, "Content-Type": "application/json"}
But as you have set your Content-Typeheader to application/jsonso I think in your PUT request you should do
但是由于您已将Content-Type标头设置为application/json所以我认为在您的 PUT 请求中您应该这样做
response = requests.put(url, data=json.dumps(data), headers=headers)
that is send your data as json.
那就是将您的数据作为 json 发送。
回答by Marcus Müller
The problem is that you try to assign datato the dataelement in your dictionary:
问题是您尝试分配data给data字典中的元素：
headers = { ..., data:data }
That can't work because you can't use a dictionary as a key in a dictionary (technically, because it's not hashable).
这是行不通的，因为您不能将字典用作字典中的键（从技术上讲，因为它不可散列）。
You probably wanted to do
你可能想做
headers = { ..., "data":data }
