Javascript React/Redux还原剂赢得'；不要从承诺中注册错误
在我的React/Redux应用程序中，我为用户创建了一个承诺，当用户尝试使用错误的凭据“登录”时，不会在我的还原程序上调用错误，当我在Auth.js文件的'login'函数中将return语句更改为未定义的变量，例如'response'而不是'error'时，它确实会调用一个错误并将其注册到我的reducer上，我查看了其他帖子，但我无法理解它。我有3个文件处理这个逻辑，Auth，Sagas和reducer。谢谢你的帮助 Auth.jsJavascript React/Redux还原剂赢得'；不要从承诺中注册错误,javascript,reactjs,redux,redux-saga,Javascript,Reactjs,Redux,Redux Saga,在我的React/Redux应用程序中，我为用户创建了一个承诺，当用户尝试使用错误的凭据“登录”时，不会在我的还原程序上调用错误，当我在Auth.js文件的'login'函数中将return语句更改为未定义的变量，例如'response'而不是'error'时，它确实会调用一个错误并将其注册到我的reducer上，我查看了其他帖子，但我无法理解它。我有3个文件处理这个逻辑，Auth，Sagas和reducer。谢谢你的帮助 Auth.js import axios from 'axios'; i

您需要抛出错误：
return axios.post(url, transformRequest(data))
.then(response => {
cookie.save('token', response.data.token, { path: '/' });
cookie.save('email', response.data.user.email, { path: '/' });
return response.data;
})
.catch((error) => {
throw error;
});
