当用户快速点击按钮时候。我们可以统一在 请求拦截 中做防止重复提交数据的处理
以下是使用uview2封装的request请求
javascript
import { autoLogin, getUserInfo } from '@/utils/method.js'
import { refreshToken } from '@/api/login.js'
const serversUrl = require('./serversUrl.js').serversUrl
// 白名单
const whiteList = [
'/szg-admin/api/app/wxLogin',
'/szg-admin/api/app/bingMobile',
'/auth/client/sms/sendCode',
'/auth/client/smsCode/login'
]
module.exports = (vm) => {
// 初始化请求配置
uni.$u.http.setConfig((defaultConfig) => {
// #ifdef H5
defaultConfig.baseURL = '/h5api'
// #endif
// #ifndef H5
defaultConfig.baseURL = serversUrl
defaultConfig.sslVerify = false
defaultConfig.firstIpv4 = false
// #endif
// 要加上这个 Content-type,不然app端请求会得不到响应
defaultConfig.header['Content-Type'] = 'application/json;charset=UTF-8'
defaultConfig.timeout = 20000
return defaultConfig
})
// 请求拦截
uni.$u.http.interceptors.request.use((config) => {
// 初始化请求拦截器时,会执行此方法,此时data为undefined,赋予默认{}
config.data = config.data || {}
// 防止数据重复提交
if (config.method === 'POST' || config.method === 'PUT' || config.method === 'DELETE') {
const requestObj = {
url: config.url,
data: typeof config.data === 'object' ? JSON.stringify(config.data) : config.data,
time: new Date().getTime()
}
const storageRequestObj = uni.getStorageSync('storageRequestObj')
if (!storageRequestObj) {
uni.setStorageSync('storageRequestObj', requestObj)
} else {
const s_url = storageRequestObj.url
const s_data = storageRequestObj.data
const s_time = storageRequestObj.time
// 间隔时间(ms),小于此时间视为重复提交
const interval = 1000
if (s_data === requestObj.data && requestObj.time - s_time < interval && s_url === requestObj.url) {
return Promise.reject('数据正在处理,请勿重复提交')
} else {
uni.setStorageSync('storageRequestObj', requestObj)
}
}
}
if (whiteList.includes(config.url)) return config
const token = uni.getStorageSync('token')
if (token) {
config.header.Authorization = `Bearer ${ token }`
}
return config
}, err => {
// 可使用async await 做异步操作
return Promise.reject(err)
})
// 响应拦截
uni.$u.http.interceptors.response.use((response) => {
// console.log('响应拦截==', response);
if (response.statusCode === 200 && response.data.code == 401) {
uni.showModal({
title: '页面停留超时',
content: '请重新进入后继续操作',
confirmText: '重新进入',
showCancel: false,
success: async e => {
uni.removeStorageSync('token')
// #ifdef MP-WEIXIN
await autoLogin()
// #endif
// #ifndef MP-WEIXIN
// 如果当前就在登录页面,不进行跳转
if (uni.$u.page() != '/pages/login') {
uni.navigateTo({ url: '/pages/login' })
}
// #endif
return Promise.reject(response.data.msg || '页面停留超时')
}
})
} else if (response.statusCode === 200) {
return response.data
} else {
uni.showModal({
title: '温馨提示',
content: response.data.msg || response.data.error,
showCancel: false
})
return Promise.reject(response.data.msg)
}
}, (err) => {
// 对响应错误做点什么 statusCode !== 200
console.log('<<<<<<响应错误>>>>>>', err)
return Promise.reject(err)
})
}
数据重复部分,可以直接复制这块代码过去放到你们的项目去
javascript
// 防止数据重复提交
if (config.method === 'POST' || config.method === 'PUT' || config.method === 'DELETE') {
const requestObj = {
url: config.url,
data: typeof config.data === 'object' ? JSON.stringify(config.data) : config.data,
time: new Date().getTime()
}
const storageRequestObj = uni.getStorageSync('storageRequestObj')
if (!storageRequestObj) {
uni.setStorageSync('storageRequestObj', requestObj)
} else {
const s_url = storageRequestObj.url
const s_data = storageRequestObj.data
const s_time = storageRequestObj.time
// 间隔时间(ms),小于此时间视为重复提交
const interval = 1000
if (s_data === requestObj.data && requestObj.time - s_time < interval && s_url === requestObj.url) {
return Promise.reject('数据正在处理,请勿重复提交')
} else {
uni.setStorageSync('storageRequestObj', requestObj)
}
}
}
