我想要一些关于线程创建和在android中调用线程的简单示例.

我正在尝试让 AWS API Gateway 使用图像进行响应。我的无服务器 Lambda 代码如下

const express = require('express');
const serverless = require('serverless-http');
const bodyParser = require('body-parser');
const request = require('request');
const fetch = require('node-fetch')
var Jimp = require('jimp');
const app = express()
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({ extended: true }))

app.get('/image/:id', async(req, res) => {
    const id = req.params.id;

    var imgUrl = 'https://developer.salesforce.com/forums/profilephoto/729F00000005O41/T';
    let options = {};

    const image = await Jimp.read(imgUrl);
    image.getBuffer(Jimp.MIME_JPEG, (err, buffer) => {
        res.set('content-type', 'image/jpeg');
        res.send(buffer.toString('base64'));
    });
});
// wrap express app instance with serverless http …

这就是阵列的出现方式

array(3) { [0]=> string(3) "174" [1]=> object(SimpleXMLElement)#5 (1) { [0]=> string(2) "41" } [2]=> object(SimpleXMLElement)#4 (1) { [0]=> string(2) "21" } } 

我在这里使用此代码生成数组.

  while($row = mysql_fetch_assoc($results)){

 $values[] = $row['id'];

    $dom = simplexml_load_file('../data/'.$row['id'].'.xml');
    foreach($dom->children() as $child)
  {
  $values[] = $child->views;
  }

  }
  var_dump($values);

xml文件如下所示

<?xml version="1.0"?>
<website site_id="174" user_id="26">
  <view day="23" month="10" year="11">
    <views>31</views>
  </view>
  <view day="23" month="12" year="11">
    <views>21</views>
  </view>
</website>

我需要将Views的值放到数组中,但是我一直在数组中获取这些烦人的 对象(SimpleXMLElement)#5.也是这个字符串(3).我该如何摆脱这些.谢谢
