+// MyWrapper<DataType>
+reqState.response;
+// MyWrapper<DataType>["data"]. maybe `undefined` type.
+reqState.data;
+```
+
 #### createRequestError
 
 The `createRequestError` normalizes the error response. This function is used internally as well. The `isCancel` flag is returned, so you don't have to call **axios.isCancel** later on the promise catch block.

 #### createRequestError
 
 `createRequestError` 用于规范错误响应（该函数也默认在内部调用）。 `isCancel` 标志被返回，因此也不必在 promise catch 块上调用 **axios.isCancel**。
