TypeError:POST数据应为字节、字节的iterable或文件对象。在python中尝试传递PUT请求时,它不能是str类型

TypeError:POST数据应为字节、字节的iterable或文件对象。在python中尝试传递PUT请求时,它不能是str类型,python,urllib,put,Python,Urllib,Put,我正在尝试将字典(字符串)列表传递给一个put请求的。我得到这个错误: TypeError:POST数据应该是字节,一个字节的iterable 这是使用python中的字典(字符串)列表发出put请求的正确方法吗 列表如下所示: list1 = ['{"id" : "","email" : "John@fullcontact.com","fullName": "John Lorang"}', '{"id" : "","email" : "Lola@fullcontact.com","fullNa

我正在尝试将字典(字符串)列表传递给一个put请求的。我得到这个错误:

TypeError:POST数据应该是字节,一个字节的iterable

这是使用
python
中的字典(字符串)列表发出put请求的正确方法吗

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)

我假设您可以使用
请求
模块(
pip安装请求

是一个简单但功能强大的HTTP libraby for Python

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()
)

正如您在一篇评论中所说,您不能使用请求(听到这个消息很伤心!),因此我使用urllib做了另一个片段(简短的回答:您必须
.encode('utf-8')
json.dumps
decode('utf-8')
响应.read()
):

我确实试着添加一些评论。我希望这个解决方案对你有帮助


为了帮助您更好地学习python,您应该阅读

请帮助我。您能使用requests软件包吗?它可能会解决您的问题。实际上,我已经安装了它,因为我尝试这是为了我的正式工作P我需要我的客户对此的权限。但是我安装了urllib,urllib。这不可能吗?有可能,我会在几个小时内回答你。当然。提前谢谢!
