从Python中使用Paypal获取访问令牌 - 使用urllib2或请求库

卷曲

curl -v https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "client_id:client_secret" \
  -d "grant_type=client_credentials"

参数: -u client_idclient_secret

在这里,我传递了client_idclient_secret,它在cURL中正常运行。

我正在尝试在Python上实现相同的东西

的Python

import urllib2
import base64
token_url = 'https://api.sandbox.paypal.com/v1/oauth2/token'
client_id = '.....'
client_secret = '....'

credentials = "%s:%s" % (client_id, client_secret)
encode_credential = base64.b64encode(credentials.encode('utf-8')).decode('utf-8').replace("\n", "")

header_params = {
    "Authorization": ("Basic %s" % encode_credential),
    "Content-Type": "application/x-www-form-urlencoded",
    "Accept": "application/json"
}
param = {
    'grant_type': 'client_credentials',
}

request = urllib2.Request(token_url, param, header_params)
response = urllib2.urlopen(request)
print "Response______", response

回溯:

  

result = urllib2.urlopen(request)

 HTTPError: HTTP Error 400: Bad Request

你能告诉我我的python代码有什么问题吗?

最新答案,但从2020年起,我使用以下python代码生成新的不记名令牌:

如果您尚未这样做,请create a new live app on developer.paypal.com
您将收到一个Client ID和一个Secret,用于生成不记名令牌。

enter image description here

Python代码:

import requests

d = {"grant_type" : "client_credentials"}
h = {"Accept": "application/json", "Accept-Language": "en_US"}

cid = "ASOGsGWr7yxepDuthbkKL-WoGNVAS7O0XlZ2ejcWsBA8ZXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
secret = "EJTKAFEYfN9IaVHc4Y-MECzgBivt2MfW6rcyfbVky0T07yRwuuTdXOczuCoEIXXXXXXXXXXXXXXX"

r = requests.post('https://api.paypal.com/v1/oauth2/token', auth=(cid, secret), headers=h, data=d).json()
access_token = r['access_token']

答案 1 :(得分:1)

我建议使用请求:

import requests
import base64

client_id = ""
client_secret = ""

credentials = "%s:%s" % (client_id, client_secret)
encode_credential = base64.b64encode(credentials.encode('utf-8')).decode('utf-8').replace("\n", "")

headers = {
    "Authorization": ("Basic %s" % encode_credential),
    'Accept': 'application/json',
    'Accept-Language': 'en_US',
}

param = {
    'grant_type': 'client_credentials',
}

url = 'https://api.sandbox.paypal.com/v1/oauth2/token'

r = requests.post(url, headers=headers, data=param)

print(r.text)

它需要URL编码:

param = {
  'grant_type': 'client_credentials',
}

data = urllib.urlencode(param)
request = urllib2.Request(token_url, data, header_params)

答案 3 :(得分:0)

这是对python 3.7有用的答案。我需要对我的身份验证凭据应用base64编码:

import base64
import requests
from backend.config import Config


def get_paypal_access_token(client_id=Config.PAYPAL_CLIENT_ID, secret=Config.PAYPAL_SECRET):
    url = "https://api.sandbox.paypal.com/v1/oauth2/token"
    payload = 'grant_type=client_credentials'
    encoded_auth = base64.b64encode((Config.PAYPAL_CLIENT_ID + ':' + Config.PAYPAL_SECRET).encode())
    headers = {
      'Authorization': f'Basic {encoded_auth.decode()}',
      'Content-Type': 'application/x-www-form-urlencoded'
    }
    r = requests.request("POST", url, headers=headers, data=payload)
    assert r.status_code == 200
    return r.json()["access_token"]

我可以通过Config文件处理我的客户ID和PayPal的机密信息,但是希望很简单,一旦注册了应用程序,便可以用自己的凭据换出这些信息。
