API FedEX“INVALID.INPUT.EXCEPTION”，“message”：“输入中的字段值无效”

Question

我正在尝试使用 Python 3.8 验证 FedEX API 中的地址，它返回无效字段值的错误

首先我连接到 Auth API

payload={"grant_type": "client_credentials",'client_id':Client_id,'client_secret':Client_secret}
url = "https://apis-sandbox.fedex.com/oauth/token"
headers = {'Content-Type': "application/x-www-form-urlencoded"}
response=requests.post(url, data=(payload), headers=headers)

并且它正确返回带有 Auth 令牌的消息

{"access_token":"eyJhbGciOiJSUzI1NiIsInRM5U0F2eUs1ZVFBVTFzS5k","token_type":"bearer","expires_in":3599,"scope":"CXS SECURE"}

然后我只需获取令牌以在中使用它接下来

token = json.loads(response.text)['access_token']

，我为地址验证 API 准备下一个有效负载

payload_valid_address = {
    "addressesToValidate": [
        {
    "address":
            {
            "streetLines": ["7372 PARKRIDGE BLVD"],
            "city": "Irving",
            "stateOrProvinceCode": "TX",
            "postalCode": "75063-8659",
            "countryCode": "US"
            }
        }
    ]
}

，并使用给定的令牌将请求发送到新端点

url = "https://apis-sandbox.fedex.com/address/v1/addresses/resolve"
headers = {
    'Content-Type': "application/json",
    'X-locale': "en_US",
    'Authorization': 'Bearer '+ token
    }

response = requests.post(url, data=payload_valid_address, headers=headers)

print(response.text)

，并收到错误消息，

<Response [422]>
{"transactionId":"50eae03e-0fec-4ec7-b068-d5c456b64fe5","errors":[{"code":"INVALID.INPUT.EXCEPTION","message":"Invalid field value in the input"}]}

我已经进行了大量测试，但没有收到无效字段。 有人知道发生了什么事并且可以提供帮助吗？

Answer 1

Payload = json.dumps({input Payload}) 这可以防止响应错误 422
<响应[422]>

Answer 2

我已经修复了它

出于任何原因，在 2 个步骤中将字符串 Payload_valid_address 转换为 Json 是行不通的，

payload_valid_address = {....}
payload = json.dumps(payload_valid_address)

但如果仅一步完成，它就会传递 API 请求

payload_valid_address = json.dumps({....})

Answer 3

我也遇到了这个错误，并且当 json 数据包含 false、true 或 null 等关键字时，还必须使用 json.loads(json_string) 。

import json

json_string = r'''{
  "accountNumber": {
    "value": "802255209"
  },
  "requestedShipment": {
    "shipper": {
      "address": {
        "postalCode": 75063,
        "countryCode": "US"
      }
    },
    "recipient": {
      "address": {
        "postalCode": "m1m1m1",
        "countryCode": "CA"
      }
    },
    "shipDateStamp": "2020-07-03",

    ],
    "customsClearanceDetail": {

        }
      },
      "commodities": [
        {

          "weight": {
            "units": "KG",
            "value": 20
          },
          "customsValue": {
            "amount": 100,
            "currency": "USD"
          }
        }
      ]
    },
    "requestedPackageLineItems": [

data = json.loads(json_string)
data

response = requests.request("POST", url, data=json.dumps(data), headers=headers)
