Question

所以我的JSON数据如下所示。我的代码行：print(jsonData["orderData"]["txnType"])打印出单词SALE，然后收到错误消息TypeError: 'NoneType' object is not subscriptable 根据我的理解，如果值明显存在并打印出来，为什么我会收到此错误？

  {  
   'orderData':{  
      'date':'2017-08-29T12:55:19-07:00',
      'receipt':'A2ZC5N96',
      'promo':{  
         '@nil':'true'
      },
      'pmtType':'PYPL',
      'txnType':'SALE',
      'item':'37',
      'amount':'104.28',
      'site':'PASSIOPROD',
      'affi':'BCPATRON2',
      'country':'US',
      'state':'OH',
      'lastName':{  
         '@nil':'true'
      },
      'firstName':{  
         '@nil':'true'
      },
      'currency':'USD',
      'email':{  
         '@nil':'true'
      },
      'zip':'43206',
      'rebillAmount':'97.00',
      'processedPayments':'1',
      'futurePayments':'998',
      'nextPaymentDate':'2017-09-29T12:55:19-07:00',
      'status':'ACTIVE',
      'accountAmount':'44.09',
      'role':'AFFILIATE',
      'customerDisplayName':{  
         '@nil':'true'
      },
      'title':'aaa',
      'recurring':'true',
      'physical':'false',
      'customerRefundableState':'REFUNDABLE'
   }
}

完整代码：

devKeys = ["KEUYS"]
apiKeys = ["API"]
sales = []
refunds = []
totalSales = []
x = 0

while x < len(devKeys):
y = 0
indSale = 0
indRefund = 0
indTotal = 0
totalTransactions = 0

payload = devKeys[x]+":"+apiKeys[x]
headers = {"Accept": "application/json", "Authorization": payload}
r = requests.get('https://api.clickbank.com/rest/1.3/orders/list', headers=headers)
jsonData = json.loads(r.text)
text = r.text
if ":[" not in text: #This line is here because the JSON looks different if theres only one entry
    print(jsonData["orderData"]["txnType"])
    if jsonData["orderData"]["txnType"] == "SALE":
        indSale+=44
        indTotal+=1
    else:
        indRefund+=44
else:
    totalTransactions = len(jsonData["orderData"])
    while y < totalTransactions:

        if jsonData["orderData"][y]["txnType"] == "SALE":
            indSale+=44
            indTotal+=1
        else:
            indRefund+=44
        y+=1

sales.append(indSale)
refunds.append(indRefund)
totalSales.append(indTotal)
x+=1

使用您的数据，我可以毫无问题地打印出正确的值，这意味着数据有效。所以请仔细检查并验证＆＃34; jsonData＆＃34;对象是＆＃34; sub-scriptable＆＃34;并拥有＆＃34; orderData＆＃34;降价时引用的密钥。好像你可能得不到预期的JSON响应。

另请参阅子脚本：In Python, what does it mean if an object is subscriptable or not?

希望它有所帮助。

当值存在python时，Python非类型错误
