如何在React Native中不使用'this'关键字的情况下访问元素的属性？我有一个与父类本身绑定为“ this”的函数，但我想访问被单击元素的属性。这是代码-

import {Circle} from 'react-native-svg';
export default App extends Component {
  constructor(props) {
  super(props);
  this.state = {activeX: null}
 }

 handleTouch(event) {
   const x = event.target.cx; //How to access "cx" property here?
   this.setState({ activeX: x });
 }

 render() {
   return (
     <Circle cx='10' cy='10' r='5' onPress={this.handleTouch.bind(this)}/>
     <Circle cx='20' cy='20' r='5' onPress={this.handleTouch.bind(this)}/>
   );
 }
}

身份验证后，地球引擎 API 通过 Initialize() 函数成功与服务器连接。

import ee
ee.Initialize()

但是，一旦我开始使用代理服务器，初始化就会失败并生成以下错误。

TimeoutError: [WinError 10060] A connection attempt failed because the 
connected party did not properly respond after a period of time, or 
established connection failed because connected host has failed to respond

我尝试过修改IPython笔记本服务器环境

import os
os.environ['HTTP_PROXY'] = 'my_proxy_id:proxy_port'
os.environ['HTTPS_PROXY'] = 'my_proxy_id:proxy_port'

ee 库仍然无法与服务器连接。如何更新代理设置？
