Error Handling
Page
404
Page-level error handling is handled uniformly by the vue-router. All pages that do not match the configured routes will redirect to the 404 page.
{ path: '*', redirect: '/404' }
WARNING
Please note that the 404 page must be loaded last. If you put 404 in the constantRoutes , then the next routes will be blocked to 404. For more details please see addRoutes when you've got a wildcard route for 404s does not work
401
Permission control is implemented in @/permission.js. All users who do not have permission to access this route will be redirected to the 401 page.
Request
All the requests in the project will go through the axios instance created in @/utils/request.js. code。
You can use the service.interceptors.response, the response interceptor, to perforrm handling error according to HTTP status codes. Such as:
service.interceptors.response.use(
...
error => {
let statusCode = error.response.status;
if (statusCode === 401) {
// Process your 401-error handler here,
}
if (statusCode === 403) {
// Process your 403-error handler here,
}
...
return Promise.reject(error);
},
);
Since all requests return a promise, you can also pass a catch error for each request, which allows for separate processing.
getInfo()
.then(res => {})
.catch(err => {
xxxx
})
Coding
This project also does code-level error handling. If you enable eslint, you will be prompted for errors when writing code. Such as:
