Uploading in other browsers is normal, but uploading in IE browser reports an error: org.springframework.web.multipart.multipartexception: failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat.util.http.fileupload.FileUploadException: Stream ended unexpectedly

Solution: just add a blank attribute under the last input attribute in the form
this is very strange: after looking for the problem all morning, many people on the Internet are wrong and can’t be solved. Later, it was found that & lt; was added under the last input attribute in the form ; input type="hidden" name="importTestUser">。

<form enctype="multipart/form-data" class="mt20 mb10">
        <div class="col-xs-offset-1">
            <input type="file" id="file" name="file" />
            <div class="mt10 pt5">
                <input type="checkbox" id="updateSupport" name="updateSupport" title="If the login account already exists, update this data." > Whether to update already existing user data
                &nbsp; <a onclick="$.table.importTemplate()" class="btn btn-default btn-xs"><i
                    class="fa fa-file-excel-o"></i> Download the template</a>
            </div>
            <input type="hidden" name="importTestUser">
            <font color="red" class="pull-left mt10">
                Hint: Only "xls" or "xlsx" format files are allowed to be imported!

[Vue warn]: Invalid prop: type check failed for prop [How to Solve]

The following situation occurs when developing projects today

[Vue warn]: invalid attribute: type check of attribute ‘list’ failed. Expected array, got object

Error reason:
subcomponent props – > List requires that the received data type is array, but the actual received data type is undefined

therefore, check the value passed by the parent component to ensure that the value passed is the data type expected by the child component.

Processing method of eslint verification error

Processing method of eslint verification error

When encountering the eslint verification rule, the following errors or warnings are reported:

1. When encountering no unused vars, no unused expressions, no undef, no restricted globals and other errors, you can verify that the function is turned off by configuring the rules in eslint
2. If there are too many errors and warnings when encountering a file (such as the imported plug-in min.js), you can create it in the root file = & gt Eslintcore (don’t forget the previous point) and configure it, as shown in the following figure:
/SRC/view = & gt; The view file under SRC file ignores the verification
[ Insert picture description here]（ https://img-blog.csdnimg.cn/49aecec84d054cc5a2e4eae7fe6fbbda.png#pic_ center

1. If eslint is configured in a separate file

Configure the required verification rules in the created. Eslintrc.js, as shown in the following figure:

2. Referenced scaffolds, such as create react app

Configure verification rules in package.json:

Vue console reports an error duplicate keys detected: ‘XXXX’. This may cause an update error. Solution

Q: the Vue console reports an error duplicate keys detected: ‘XXXX’. This may cause an update error. Solution

Analysis: duplicate key: ‘0’. 0 ‘may cause an update error; This problem usually occurs because there are multiple V-for loops on the same page, and the key of the loop is index. You can define the key as a unique value, such as code or ID. this can be solved
A: the value of the drop-down box must be unique. Check the value of the drop-down box

[Solved] Vue + uniapp Uncaught TypeError: Cannot read property ‘getters‘ of undefined

Uncaught TypeError: Cannot read property ‘getters’ of undefined
When migrating vuex-related code, the startup reports: Uncaught TypeError: Cannot read property 'getters' of undefined

store/index.js File:

import Vue from 'vue'
import Vuex from 'vuex'

import getters from './getters.js'

Vue.use(Vuex)

// https://webpack.js.org/guides/dependency-management/#requirecontext
const modulesFiles = require.context('./modules', true, /\.js$/)

// you do not need `import app from './modules/app'`
// it will auto require all vuex module from modules file
const modules = modulesFiles.keys().reduce((modules, modulePath) => {
  // set './app.js' => 'app'
  const moduleName = modulePath.replace(/^\.\/(.*)\.\w+$/, '$1')
  const value = modulesFiles(modulePath)
  modules[moduleName] = value.default
  return modules
}, {})

const store = new Vuex.Store({
	modules,
	getters
})
export default store

All. JS files in the modules directory obtained at this time are saved as vuex of named attributes.

Solution: the reason is that a file under my modules has not been written empty. Just delete it temporarily.
