如何使用python请求发布一个base64文件的Json ?

Question

现在我正在用python编程API，我有以下问题:我必须POST以下JSON到一个url:

prescription = {
"Name": “file_name", # This is a string
"Body" : "xxx",# (File in base64 format)
"ParentId" : "xxxxxxxxxxxxxxxxxx", # This is a string
"ContentType" : "xxxxx/xxx" # This is a string
}

但是当我尝试做以下请求时:

requests.post(url, prescription)

我得到以下错误:

TypeError: Object of type bytes is not JSON serializable

我怎么能使张贴JSON的请求?这可能吗?

谢谢你的帮助。

编辑:使用

"Body" : "xxx.decode("utf-8")"

工作了，谢谢你的帮助

您可以这样做:

import base64
import requests
with open("your/file", "rb") as file:
b64_file_content= base64.b64encode(file.read())
prescription = {
"Name": "file_name",  # This is a string
"Body": b64_file_content.decode("ascii"),  # (File in base64 format)
"ParentId": "xxxxxxxxxxxxxxxxxx",  # This is a string
"ContentType": "xxxxx/xxx",  # This is a string
}
requests.post("https://somewhere.world", prescription)
