From af0e0a110e7187bf008655f7510199a0c0b25ec4 Mon Sep 17 00:00:00 2001 From: Nymph2333 <498092988@qq.com> Date: 星期一, 10 四月 2023 14:27:40 +0800 Subject: [PATCH] newInstance() 已弃用,使用clazz.getDeclaredConstructor().newInstance() This method propagates any exception thrown by the nullary constructor, including a checked exception. Use of this method effectively bypasses the compile-time exception checking that would otherwise be performed by the compiler. The Constructor.newInstance method avoids this problem by wrapping any exception thrown by the constructor in a (checked) InvocationTargetException. The call clazz.newInstance() can be replaced by clazz.getDeclaredConstructor().newInstance() The latter sequence of calls is inferred to be able to throw the additional exception types InvocationTargetException and NoSuchMethodException. Both of these exception types are subclasses of ReflectiveOperationException. --- ruoyi-ui/src/utils/request.js | 130 ++++++++++++++++++++++++++++-------------- 1 files changed, 86 insertions(+), 44 deletions(-) diff --git a/ruoyi-ui/src/utils/request.js b/ruoyi-ui/src/utils/request.js index b9b5ad8..8797e3f 100644 --- a/ruoyi-ui/src/utils/request.js +++ b/ruoyi-ui/src/utils/request.js @@ -1,8 +1,15 @@ import axios from 'axios' -import { Notification, MessageBox, Message } from 'element-ui' +import { Notification, MessageBox, Message, Loading } from 'element-ui' import store from '@/store' import { getToken } from '@/utils/auth' import errorCode from '@/utils/errorCode' +import { tansParams, blobValidate } from "@/utils/ruoyi"; +import cache from '@/plugins/cache' +import { saveAs } from 'file-saver' + +let downloadLoadingInstance; +// 是否显示重新登录 +export let isRelogin = { show: false }; axios.defaults.headers['Content-Type'] = 'application/json;charset=utf-8' // 创建axios实例 @@ -12,34 +19,45 @@ // 超时 timeout: 10000 }) + // request拦截器 service.interceptors.request.use(config => { // 是否需要设置 token const isToken = (config.headers || {}).isToken === false + // 是否需要防止数据重复提交 + const isRepeatSubmit = (config.headers || {}).repeatSubmit === false if (getToken() && !isToken) { config.headers['Authorization'] = 'Bearer ' + getToken() // 让每个请求携带自定义token 请根据实际情况自行修改 } // get请求映射params参数 if (config.method === 'get' && config.params) { - let url = config.url + '?'; - for (const propName of Object.keys(config.params)) { - const value = config.params[propName]; - var part = encodeURIComponent(propName) + "="; - if (value !== null && typeof(value) !== "undefined") { - if (typeof value === 'object') { - for (const key of Object.keys(value)) { - let params = propName + '[' + key + ']'; - var subPart = encodeURIComponent(params) + "="; - url += subPart + encodeURIComponent(value[key]) + "&"; - } - } else { - url += part + encodeURIComponent(value) + "&"; - } - } - } + let url = config.url + '?' + tansParams(config.params); url = url.slice(0, -1); config.params = {}; config.url = url; + } + if (!isRepeatSubmit && (config.method === 'post' || config.method === 'put')) { + const requestObj = { + url: config.url, + data: typeof config.data === 'object' ?
