postman请求正常，python请求报“服务端异常”

今天写登录的时候，用postman请求是正常的，用python写的请求返回服务器异常，最后找到的原因是data数据传过去的默认是字符串

import requests
class HttpRequest:
    def http_request(self, method, url, data=None, header = None, cookie=None):
        if method.lower() == 'get':
            res = requests.get(url,data, headers = header, cookies = cookie, verify = False)
        elif method.lower() == 'post':
            res = requests.post(url, data, headers = header, cookies = cookie,  verify = False)
        elif method.lower() == 'put':
            res = requests.post(url, data, headers = header, cookies = cookie,  verify = False)
        else:
            print("没有此方法，请联系管理员")
            return
        return res
if __name__ == '__main__':
    method = 'post'
    url = 'https:www.account/v2/session/loginByOne?corpId=8GUafWTqYo0o00'
    data = {"fullPhone":"86-17610296533","password":"123456"}
    header = {'Content-Type': 'application/json'}
    res = HttpRequest().http_request(method, url, data, header)
    print(res)

需要将data修改成json修改代码如下

import requests
class HttpRequest:
    def http_request(self, method, url, data=None, header = None, cookie=None):
        if method.lower() == 'get':
            res = requests.get(url, json = data, headers = header, cookies = cookie, verify = False)
        elif method.lower() == 'post':
            res = requests.post(url, json = data, headers = header, cookies = cookie,  verify = False)
        elif method.lower() == 'put':
            res = requests.post(url, json = data, headers = header, cookies = cookie,  verify = False)
        else:
            print("没有此方法，请联系管理员")
            return
        return res
if __name__ == '__main__':
    method = 'post'
    url = 'https://account/v2/session/loginByOne?corpId=8GUafWTqYo0o00'
    data = {"fullPhone":"86-17610296533","password":"123456"}
    header = {'Content-Type': 'application/json'}
    res = HttpRequest().http_request(method, url, data, header)
    print(res)
