我有一个React应用程序，试图从AWS访问无服务器。但是我有下面的错误

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.test.com' is therefore not allowed access. The response had HTTP status code 502.

端点网址为https://key.execute-api.ap-southeast-2.amazonaws.com/dev/samplefunction

在serverless.yml上的设置是

login:
    handler: login.login
    events:
      - http:
          path: login
          method: post
          cors:
            origin: 'https://admin.differentdomain.com'
            headers:
              - MY_CUSTOM_HEADER
              - Content-Type
              - X-Amz-Date
              - Authorization
              - X-Api-Key
              - X-Amz-Security-Token

我还有其他地方需要进行CORS配置吗？

当我尝试执行以下代码时，我的反应本机应用程序出现错误

react-native run-android --variant=release

Starting a Gradle Daemon (subsequent builds will be faster)

> Configure project :react-native-firebase
react-native-firebase: using React Native prebuilt binary from /Users/sanglee/Documents/react-native-firebase-starter/node_modules/react-native/android

FAILURE: Build failed with an exception.

* What went wrong:
Task 'installDebug' not found in project ':app'.

我从react-native-firebase下载了react-native应用程序，甚至无法使用android进行测试。

我正在为 React 项目编写单元测试代码。我正在尝试测试一个功能

//function aa
export const login = (values) => async => (dispatch) => {
  let bodyFormData = new FormData();

  bodyFormData.append('username', values.login);
  bodyFormData.append('password', values.password);
  return await axios({
   method: 'post',
   url: url,
   data: bodyFormData
  }
}

//aa test
it("Login Action", async () => {
  afterEach(() => {
    store.clearActions();
  });
  const values = {
    login: "aaaaa",
    password: "bbbbb"
  };
  const expectedResult = { type: "LOGIN_PASS" };

  const result = await store.dispatch(login(values));
  expect(result).toEqual(expectedResult);
});

在浏览器中，这工作正常。但是在测试时我得到以下错误

参考错误：未定义 FormData

我尝试使用此模块但没有运气... https://www.npmjs.com/package/form-data

我不想只测试 axios，我需要测试完整的功能。
