使用requests模块post payload请求

import json
import requests
import datetime

postUrl = 'https://sellercentral.amazon.com/fba/profitabilitycalculator/getafnfee?profitcalcToken=en2kXFaY81m513NydhTZ9sdb6hoj3D'
# payloadData数据
payloadData = {
'afnPriceStr': 10,
'currency':'USD',
'productInfoMapping': {
'asin': 'B072JW3Z6L',
'dimensionUnit': 'inches',
}
}
# 请求头设置
payloadHeader = {
'Host': 'sellercentral.amazon.com',
'Content-Type': 'application/json',
}
# 下载超时
timeOut = 25
# 代理
proxy = "183.12.50.118:8080"
proxies = {
"http": proxy,
"https": proxy,
}
r = requests.post(postUrl, data=json.dumps(payloadData), headers=payloadHeader)
dumpJsonData = json.dumps(payloadData)
print(f"dumpJsonData = {dumpJsonData}")
res = requests.post(postUrl, data=dumpJsonData, headers=payloadHeader, timeout=timeOut, proxies=proxies, allow_redirects=True)
# 下面这种直接填充json参数的方式也OK
# res = requests.post(postUrl, json=payloadData, headers=header)
print(f"responseTime = {datetime.datetime.now()}, statusCode = {res.status_code}, res text = {res.text}")
