将curl POST转换为urllib请求python3

Question

以下curl命令可按预期工作。 使用POST将一些信息发送到网站。

    curl 'https://...' \
     -X PUT \
     -d "submission[posted_grade]=65" \
     -H "Authorization: Bearer 10~X" 

等效的python3代码应该是什么，给出错误500：Internal Server Error

url_string = 'https://...'
data = "submission[posted_grade]=40"
data = data.encode('utf-8')
req = urllib.request.Request(url_string, data)
req.add_header("Authorization", "Bearer 10~X")
req.add_header("Content-Type", "application/json")
response = urllib.request.urlopen(req)
print(response.read())

已经尝试过

data = {'submission[posted_grade]': '40'}
data = json.dumps(data)
data = data.encode('utf-8')

给出“ HTTP错误422：无法处理的实体”

有修复的想法吗？

谢谢@cody

获得的经验教训，PUT！= POST

以下代码按预期工作：

url_string = 'https://...'
data = "submission[posted_grade]=40"
data = data.encode('utf-8')
req = urllib.request.Request(url=url_string, data=data, method='PUT')
req.add_header("Authorization", "Bearer 10~X")
response = urllib.request.urlopen(req)
