怎么在app里支持 TextEncoder方法

4***@qq.com (作者)

试了下 有点尴尬。又报错 Big integer literals are not available in the configured target environment ("es2015")

我需要用protobuf-ts 包装 数据

回复 jgj_app:

<template>

<button @click="toHome">qweq</button>

<button @click="toBluetooth">Bluetooth</button>

<button @click="welcome.toSendBluetooth">蓝牙发送</button>

</template>

<script setup lang="ts">

import BleService from '../../services/ble';

import {CommandId} from "../../proto/command_id_enum";

import {onMounted} from 'vue';

const toSendBluetooth = async (id, data) => {

const body = {

value: {

oneofKind: 'intVal',

intVal: 90, // 模拟baohedu 90

}

}

console.log(1222)

const res3 = await BleService.sendSetRequest(id, body);

console.log('sendData:', res3);

uni.showModal({

title: '提示',

content: '发送成功',

showCancel: false,

success: (res) => {

}

});

}

const toHome = () => {

uni.navigateTo({

url: '/pages/home/index'

})

}

const toBluetooth = () => {

uni.navigateTo({

url: '/pages/bluetooth/index'

})

}

onMounted(() => {

startReadBluetooth();

});

const stringToAnyArray = (str: string): any[] => {

const bytes = [];

for (let i = 0; i < str.length; i++) {

// 将字符编码为 UTF-8 字节

let code = str.charCodeAt(i);

if (code <= 0x7F) {

bytes.push(code);

} else if (code <= 0x7FF) {

bytes.push(0xC0 | (code >> 6));

bytes.push(0x80 | (code & 0x3F));

} else if (code <= 0xFFFF) {

bytes.push(0xE0 | (code >> 12));

bytes.push(0x80 | ((code >> 6) & 0x3F));

bytes.push(0x80 | (code & 0x3F));

} else {

bytes.push(0xF0 | (code >> 18));

bytes.push(0x80 | ((code >> 12) & 0x3F));

bytes.push(0x80 | ((code >> 6) & 0x3F));

bytes.push(0x80 | (code & 0x3F));

}

}

return bytes;

};

const startReadBluetooth = () => {

setInterval(() => {

if (!BleService.isrReading && BleService.getDeviceId()!='') {

BleService.readBLECharacteristicValue();

}

}, 1000);

}

defineExpose({

toSendBluetooth

})

</script>

<script module="welcome" lang="renderjs">

export default {  

    methods: {  

    toSendBluetooth(ev, ownerInstance) {  

        console.log(11)  

        this.$ownerInstance.callMethod('toSendBluetooth')  

    }  



    }  

}  

</script>

尝试了这种写法 好像调用不到 外部方法

无语了 就算不用 BIgInt renderjs 也没法 import 一个script

BleService 是一个单例 ts文件

renderjs。也没法import 引用

太难玩 uniapp

情况就是 我有一个外部的蓝牙 ts ，这个ts引用了 @protobuf-ts的库 （这个库用了 TextEncoder、big Int 这些东西）然后uniapp app 就不行了
