Zapier 操作代码：Python 不会运行与 input_data 变量

Question

我正在使用 Zapier 捕获网络钩子并将该信息用于 API post。使用“4111111111111111”代替 doSale 中的 Ccnum，操作代码运行良好。但是，当我使用 input_data 变量并将其放入 doSale 时，它会出错。

Zapier 输入变量：

print gw.responses['response']

if (int(gw.responses['response']) == 1) :
    print "Approved"
elif (int(gw.responses['response']) == 2) :
    print "Declined"
elif (int(gw.responses['response']) == 3) :
    print "Error"

到最后才是问题所在。如何将变量从 Zapier 传递到 python 代码？

Answer 1

来自 Zapier Platform 团队的 David。一些东西。

首先，我认为您的问题与 here 中描述的问题相同。也就是说，我相信 input_data 的值是 unicode。因此，您需要调用 str(input_data['Ccnum'])。

或者，如果您想使用 Requests，它也受支持并且不那么挑剔。

综上所述，如果我没有提到 Zapier 代码步骤中的所有内容都在内部以纯文本形式记录，那我就是失职了。出于这个原因，我强烈建议不要将信用卡号、此服务的密码以及任何其他敏感数据放入代码步骤。您控制的私人服务器是一个更安全的选择。

如果您还有其他问题，请告诉我！
