Django API TypeError:字符串索引必须是整数，而不是str

Question

我正在编写一个API来将数据保存到模型中，目前正在处理string indices must be integers, not str的错误。我已经在网上寻找解决方案，包括这个网站上关于这个错误的许多问题，到目前为止还没有找到解决方案。我现在在代码中包含了一个try-except语句，因为服务器只是说错误是内部的，try-except提供了对代码出错原因的更多了解。我已经仔细检查过了，相当肯定我的铸件是正确的。我在下面包含了我的代码。如有任何建议，我们将不胜感激

您需要在try语句之后进行转储。当您转储该值时，它将变为字符串，并在加载时dict

希望有帮助
