python - PayPal 错误 10002 使用权限 API 和 TransactionSearch

Question

我有一个如下所示的权限请求:

timestamp, signature = genPermissionsAuthHeader.getAuthHeader(str(self.username), str(self.password), str(access_token), str(token_secret), "POST", "https://api-3t.sandbox.paypal.com/nvp") # https://svcs.sandbox.paypal.com/Permissions/GetBasicPersonalData
        log.info(timestamp)
        log.info(signature)
    authorization_header = "timestamp=" + timestamp + ",token=" + access_token + ",signature=" + signature
    log.info(authorization_header)

    headers = {
        "X-PAYPAL-AUTHORIZATION": authorization_header,
    }

    url = "https://api-3t.sandbox.paypal.com/nvp"

    nvp_params = {
        "METHOD": "TransactionSearch",
        "STARTDATE": "2012-01-01T05:38:48Z",
    }

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

    log.info(r.text)
    self.response.content_disposition = "text/html"
    self.response.write(r.text)

我在 developer.paypal.com 上的“沙盒帐户”下使用我的 PayPal 凭据从权限 API 获得了访问 token 和 token secret

当我运行此方法时，我收到错误消息:

TIMESTAMP=2014%2d04%2d21T22%3a50%3a18Z&CORRELATIONID=c8f9212035b60
&ACK=Failure&VERSION=0%2e000000&BUILD=10277387&L_ERRORCODE0=10002
&L_SHORTMESSAGE0=Authentication%2f
Authorization%20Faile
d&L_LONGMESSAGE0=You%20do%20not%20have%20permissions%20to%20make%20this%20API%20call
&L_SEVERITYCODE0=ErrorNone

我可以调用 GetBasicPersonalDetails，它似乎有效。任何帮助都会很棒，谢谢!

我找到了答案，我在为付款发送的参数字符串中缺少“SUBJECT”参数。因此，以防万一其他人在未来遇到这个问题，在获得权限 token 以运行沙箱测试支付后的完整代码是:

def test_sales(self, access_token=None, token_secret=None):

timestamp, signature = genPermissionsAuthHeader.getAuthHeader(str(self.username), str(self.password), str(access_token), str(token_secret), "POST", "https://api-3t.sandbox.paypal.com/nvp") # https://svcs.sandbox.paypal.com/Permissions/GetBasicPersonalData
log.info(timestamp)
log.info(signature)

authorization_header = "timestamp=" + timestamp + ",token=" + access_token + ",signature=" + signature
log.info(authorization_header)

headers = {
    "X-PAYPAL-AUTHORIZATION": authorization_header,
}

url = "https://api-3t.sandbox.paypal.com/nvp"

nvp_params = {
    "METHOD": "DoDirectPayment",
    "PAYMENTACTION": "Sale",
    "AMT": "22.00",
    "ACCT": "4111111111111111",
    "CVV2": "111",
    "FIRSTNAME": "Jane",
    "LASTNAME": "Smith",
    "EXPDATE": "012018",
    "IPADDRESS": "127.0.0.1",
    "STREET": "123 Street Way",
    "CITY": "Englewood",
    "STATE": "CO",
    "ZIP": "80112",
    "VERSION": "86",
    "SIGNATURE": self.signature,
    "USER": self.username,
    "PWD": self.password,
    "SUBJECT": "person_who_you_acting_on_behalf_of@domain.com"
}


r = requests.post(url, data=nvp_params, headers=headers)
log.info("Search transaction\n\n" + r.text + "\n\n")
self.response.content_disposition = "text/html"
self.response.write(urllib.unquote(r.text).decode('utf8'))

为了生成 header ，我使用了:https://github.com/paypal/python-signature-generator-for-authentication-header

希望这对某人有帮助，谢谢!
