Taro小程序接入流式接口

import Taro from '@tarojs/taro';
import * as TextEncoding from 'text-encoding-shim';

export function eventSource({url,data,onmessage,onerror}) {
    const requestTask = Taro.request({
        url: url,
        enableChunked: true,
        header: {'Content-Type': 'application/json'},
        method: 'POST',
        data: data, // 按照你所对接API接口
        success: (res) => {
          console.info('发送成功',res)
        },
        fail(e) {
            onerror(e)
        }
    })
    requestTask.onChunkReceived((response) => {
        const str = new TextEncoding.TextDecoder('utf-8').decode(
            new Uint8Array(response.data)
        )
        onmessage(str)
    })
