404 读取余额账户Api时的响应。

Question

import paypalrestsdk
import httpx


class paypal:
    def __init__(self):
        self.secret_id = 'XXXX'
        self.client_id = 'XXXX'

        self.token = ''

    def getToken(self):
        headers = {
            'Accept': 'application/json',
            'Accept-Language': 'en_US',
        }

        data = {
            'grant_type': 'client_credentials'
        }
        response = httpx.post(url='https://api.sandbox.paypal.com/v1/oauth2/token', data=data,headers=headers,auth=(self.client_id,self.secret_id))
        response_data = response.json()
        self.token = response_data['access_token']

    def getBalance(self):
        print(self.token)
        headers = {
            'Content-Type': 'application/json',
            'Authorization': 'Bearer '+self.token,
            'Accept':'application/x-www-form-urlencoded'
        }
        response = httpx.post(url='https://api.sandbox.paypal.com/v2/wallet/balance-accounts', headers=headers)
        print(response.status_code)
        response_data = response.json()
        print(response_data)


        available = response_data['total_available'][0]['value']
        print(response_data)


if __name__ == "__main__":
    s = paypal()
    s.getToken()
    s.getBalance()

我得到404代码，我是不是做了什么坏事？

    Traceback (most recent call last):
  File "C:/Users/localhost/PycharmProjects/Telegram/paypal/Main.py", line 48, in <module>
    s.getBalance()
  File "C:/Users/localhost/PycharmProjects/Telegram/paypal/Main.py", line 37, in getBalance
    response_data = response.json()

我也尝试用 "Authorization: 但得到的回应是一样的，我读了文档并搜索了一下，我没有发现任何东西，而且访问令牌是新的，所以我不明白，因为我得到的访问令牌是有效的。

你正在发送一个 POST 请求而不是 GET 请求。使用 httpx.get 而不是 httpx.post.

你甚至可以使用 httpx_auth 以使你的代码集中在你想检索的内容上。

import paypalrestsdk
import httpx
import httpx_auth


class paypal:
    def __init__(self):
        self.auth = httpx_auth.OAuth2ClientCredentials(
            token_url='https://api.sandbox.paypal.com/v1/oauth2/token',
            client_id='XXXX',
            client_secret='XXXX',
        )

    def getBalance(self):
        response = httpx.get(url='https://api.sandbox.paypal.com/v2/wallet/balance-accounts', auth=self.auth)
        print(response.status_code)
        response_data = response.json()
        print(response_data)


        available = response_data['total_available'][0]['value']
        print(response_data)


if __name__ == "__main__":
    s = paypal()
    s.getBalance()
