TypeError:POST数据应该是字节、字节的iterable或file对象。在python中尝试传递PUT请求时，它不能是str类型

Question

我正在尝试将字典（字符串）列表传递给一个请求put的。我得到这个错误：

TypeError: POST data should be bytes, an iterable of bytes.

这是用python中的字典（字符串）列表发出put请求的正确方法。你知道吗

列表如下所示：

list1 = ['{"id" : "","email" : "John@fullcontact.com","fullName": "John Lorang"}', '{"id" : "","email" : "Lola@fullcontact.com","fullName": "Lola Dsilva"}']


myData = json.dumps(list1)
myRestRequestObj = urllib.request.Request(url,myData)
myRestRequestObj.add_header('Content-Type','application/json')
myRestRequestObj.add_header('Authorization','Basic %s')
myRestRequestObj.get_method = lambda : 'PUT'
try:
  myRestRequestResponse = urllib.request.urlopen(myRestRequestObj)
except urllib.error.URLError as e:
        print(e.reason)

Answer 1

我假设您可以使用requests模块（pip install requests）。你知道吗

requests是Python的一个简单而强大的HTTP库。你知道吗

import json
import requests

my_data = json.dumps(list1)
headers = {
    'Authorization': 'Basic {token}'.format(token=your_token)
}

response = requests.put(url, headers=headers, json=my_data)

print("Status code: {status}".format(status=response.status_code))
print("raw response: {raw_response}".format(
    raw_response=response.text
)
print("json response: {json_response}".format(
    json_response=response.json()
)
