读取 http/2 推送流失败并出现错误 -505

Question

我正在尝试读取 http/2 推送流，但下面的代码失败并出现错误。当我在 Chrome 浏览器中使用相同的 URL 时，我会收到流服务器生成的“心跳”，并且也可以看到传入的数据。任何指针？我的目标只是读取服务器生成的所有 JSON 推送响应。

Error:
{ Error [ERR_HTTP2_ERROR]: Protocol error
    at Http2Session.onSessionInternalError [as error] (internal/http2/core.js:637:26)
  code: 'ERR_HTTP2_ERROR',
  name: 'Error [ERR_HTTP2_ERROR]',
  errno: -505 }

Node.JS 代码：

const http2 = require('http2');
const client = http2.connect('http://api.service.com/absolute/path/subscribe?api_key={key}');

const req = client.request();
req.setEncoding('utf8');

req.on('response', (headers, flags) => {
  console.log(headers);
});

let data = '';
req.on('data', (d) => data += d);
req.on('end', () => {
    console.log('end');
    console.log(data); 
    client.destroy()
});
req.end();

旁注：我是 Node.js 新手，http/2 推送流对我来说也是一个新话题，所以请考虑我是初学者，正在为此苦苦挣扎。

在一些帮助下解决，使用“请求”库： https://www.npmjs.com/package/request

const request = require("request");

const getPushData = () => {
    let completeResponse = "";
    request
    .get('http://api.service.com/absolute/path/subscribe?api_key={key}')
    .on('response', (response)=>{
        console.log("Response received successfully");
    })
    .on('data', (chunk)=>{
        console.log("Receiving the chunk...");
        console.log(chunk);
        let dataReceived = new Buffer(chunk).toString("utf8");
        console.log(dataReceived);

        completeResponse += chunk;        
    })
    .on('error', (err)=>{
        console.log("Something went wrong:");
        console.log(err.message);
    })
    .on("end", ()=>{
        console.log("The complete data received is:");
        console.log(completeResponse);
        let jsonObj = JSON.parse(completeResponse); 
        console.log(jsonObj);
    });
}

getPushData();

旁注：此脚本的问题在于，如果连接断开，则流不会恢复。
