python multipart/form-data post接口请求

def WebKit_format(data, boundary="----WebKitFormBoundary*********ABC", headers=None):
        # 从headers中提取boundary信息
        if headers is None:
            headers = {}
        if "content-type" in headers:
            fd_val = str(headers["content-type"])
            if "boundary" in fd_val:
                fd_val = fd_val.split(";")[1].strip()
                boundary = fd_val.split("=")[1].strip()
            else:
                raise Exception("multipart/form-data头信息错误，请检查content-type key是否包含boundary")
        # form-data格式定式
        jion_str = '--{}\r\nContent-Disposition: form-data; name="{}"\r\n\r\n{}\r\n'
        end_str = "--{}--".format(boundary)
        args_str = ""
        if not isinstance(data, dict):
            raise Exception("multipart/form-data参数错误，data参数应为dict类型")
        for key, value in data.items():
            args_str = args_str + jion_str.format(boundary, key, value)
        args_str = args_str + end_str.format(boundary)
        args_str = args_str.replace("\'", "\"")
        return args_str




    def test001_auth_login():
        headers = {'Accept': "application/json", 'Content-Type': "multipart/form-data; boundary=----WebKitFormBoundary*********ABC",
                   'Accept-Encoding': "gzip, deflate, br", 'Connection': "keep-alive"}
        url = "https://www.baidu.com/login/"
        bodyData = {
            "username": 1234567890,
            "password": "a123456",
            "type": "account",
            "bindType": "null",
            "openId": "null"
        }
        boundary_body = WebKit_format(data=bodyData, headers=headers)
        print(boundary_body)
        response = requests.post(url, data = boundary_body, headers = headers)
        access_token = regSearchString(response.text, '"access_token":"(.+?)",', 16, -2)
        print("正则--获取登陆的access_token:  " + access_token)
        print(response.text)
        time.sleep(1)

boundary_body = WebKit_format(data=bodyData, headers=headers)

 转换后的boundary_body 类似下面：

------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="v"

2.0
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="req"

{"cno": "1213058673616305"}
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="sig"
