前言

uniapp默认是不支持event-source，这里是借助renderjs进行SSE连接

正文

引入event-source-polyfill
这里演示的是直接将代码下载到本地进行引入
下载地址

把里面的eventsource.min.js文件放到项目中的static文件夹
项目封装event-source.vue组件

<template><view :prop="info" :change:prop="sse.onChange" id="renderjs-view" />
</template><script>
import { BASE_URL } from "@/utils/config"
import { getToken } from "@/utils/auth"
import { storage } from "@/utils"export default {data() {return {info: {}}},created() {this.setInfo()},methods: {setInfo() {this.info = { url: BASE_URL, token: getToken(), userId: storage.getItem("userId") }},onMessage(e) {this.$emit('message', e)}}
}
</script><script module="sse" lang="renderjs">export default {data() {return { sseInfo:{}}},mounted() {this.setSSE()},methods: {setSSE() {if (typeof EventSourcePolyfill === "function") {this.initSSE()} else {const script = document.createElement('script')script.src = "static/js/eventsource.min.js"script.type = "text/javascript"script.onload = this.initSSE.bind(this)document.head.appendChild(script)}},initSSE() {const sse =  new EventSourcePolyfill(`${this.sseInfo.url}/sse/system-sse/sse-server?userId=${this.sseInfo.userId}_${Date.now()}`, {headers: {Authorization: "Bearer " + this.sseInfo.token,"Tenant-Id": 1}})sse.onmessage = (e) => {this.$ownerInstance.callMethod('onMessage', e)}},onChange(value) {this.sseInfo = value},}}
</script>

外部使用

<EventSource @message="onMessage"/><script lang="ts" setup>const onMessage = (e) => {// uni.showModal({// 	title: 'sse消息',// 	content: e.data,// })console.log("sse消息：",e)}
</script>
