如何在 Python 中使用这个 API？ 我就是不能

Question

So i'm trying to consume this API, I got this URLhttp://www.ventamovil.com.mx:9092/service.asmx?op=Check_Balance

在那里，您可以在输入字段上写下 {"User":"6144135400","Password":"Prueba$$"} 并得到响应。

但是当我尝试在 python 上消费这个 api 时，我就是不能，我不知道如何正确消费：

我的代码

如您所见，我的代码得到了不同的响应，我应该得到与“响应”图像相同的响应。

为了节省一些时间，您可以使用他们的请求自动构建 python 代码，您所要做的就是：

• 就像一开始一样，在输入字段中输入 json 并调用。
• 打开网络选项卡，将他们发出的帖子请求复制为 curl

curl 'http://www.ventamovil.com.mx:9092/service.asmx/Check_Balance' -H 'Connection: keep-alive' -H 'Cache-Control: max-age=0' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.122 Safari/537.36' -H 'Origin: http://www.ventamovil.com.mx:9092' -H 'Content-Type: application/x-www-form-urlencoded' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9' -H 'Referer: http://www.ventamovil.com.mx:9092/service.asmx?op=Check_Balance' -H 'Accept-Language: en-US,en;q=0.9,ar;q=0.8,pt;q=0.7' --data 'jrquest=%7B%22User%22%3A6144135400%2C+%22Password%22%3A+%22Prueba%24%24%22%7D' --compressed --insecure

• Go to postman and import the curl, then click code and select python, and here you go you have all the right headers needed

import requests

url = "http://www.ventamovil.com.mx:9092/service.asmx/Check_Balance"

payload = 'jrquest=%7B%22User%22%3A6144135400%2C+%22Password%22%3A+%22Prueba%24%24%22%7D'
headers = {
  'Upgrade-Insecure-Requests': '1',
  'Content-Type': 'application/x-www-form-urlencoded',
  'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9',
}

response = requests.request("POST", url, headers=headers, data = payload)

print(response.text.encode('utf8'))

如您所见，它们将输入作为表单编码的有效负载接受。

您需要修改此请求以在每次使用时使用您想要的用户/密码进行参数化。

顺便说一句，这个 python 代码的 output 是：

b'<?xml version="1.0" encoding="utf-8"?>\r\n<string xmlns="http://www.ventamovil.com.mx/ws/">{"Confirmation":"00","Saldo_Inicial":"10000","Compras":"9360","Ventas":"8416","Comision":"469","Balance":"10345.92"}</string>'
