我尝试使用入口点和cmd设置Docker.

FROM debian:stretch
RUN apt-get update && \
apt install gnupg ca-certificates -y 
RUN echo "deb http://repo.aptly.info/ squeeze main" > /etc/apt/sources.list.d/aptly.list
RUN apt-key adv --keyserver keys.gnupg.net --recv-keys 9E3E53F19C7DE460
RUN apt update && apt install aptly -y
ADD aptly.conf /etc/aptly.conf
ADD start.sh .
VOLUME ["/aptly"]
ENTRYPOINT ["/start.sh"]
CMD ["aptly", "api", "serve"]

但是入口点脚本没有停止...... cmd命令没有启动

我的脚本在这里:

#!/bin/bash
 set -e 
 init_aptly() { 
 #import pgp key
#create nginx root folder in /aptly
su -c "mkdir -p /aptly/.aptly/public"
echo "12"
 #initialize repository
 #aptly create repo doze-server …

我尝试在输入文本中获取值，并使用 react-bootstrap 将其添加到文本区域。

我知道我必须使用 ReactDOM.findDOMNode 来获取 ref 的值。我不明白出了什么问题。

这是我的代码：

import React from 'react';
import logo from './logo.svg';
import ReactDOM from 'react-dom';
import { InputGroup, FormGroup, FormControl, Button} from 'react-bootstrap';
import './App.css';
class InputMessages extends React.Component {
constructor(props) { 
super(props);
this.handleChange =      this.handleChange.bind(this); 
    this.GetMessage= this.GetMessage.bind(this); 
this.state = {message: ''};
}   
handleChange(event)
{    
this.setState({message: this.GetMessage.value});
}
GetMessage()
{   
return ReactDOM.findDOMNode(this.refs.message     );
 }
 render() {
    var message = this.state.message;
    return(
 <FormGroup > 
 <FormControl
 componentClass="textarea" value={message} />
 <InputGroup> 
 <FormControl type="text" ref='message' /> 
    <InputGroup.Button>
    <Button …

我用 Rust 做了服务器更新。它在两个二进制文件之间创建补丁，并提供静态文件

我尝试做

    let mut update_state;
    if let Some(state) = update_stream.next().await {
        if let Ok(state) = state {
            update_state = state
        } else if let Err(err) = state {
            reply = BuildOutput { error: "Update failed: ".to_string() + &err.to_string() }
        }
    } else {
        reply = BuildOutput { error: "Unreacheable".to_string() }
    }

    let state = update_state.borrow();
    let progress = state.histogram.progress();

    let res = update_stream.try_for_each(|_state| future::ready(Ok(()))).await;

但得到

note: future is not `Send` as this value is used across an await …

我想为我的反应组件（Navlink）设置颜色“白色”。主页和日志链接始终是暗的:(从来没有设置白色。我使用Reacstrap，Bootstap4。我用CSS分隔js，这是我的代码：

Sidebar.js

import React from 'react';
import { NavLink as RouterNavLink } from 'react-router-dom';
import { Collapse, Navbar, NavbarToggler, NavbarBrand, Nav, NavItem, NavLink 
} from 'reactstrap';
import './Sidebar.css';

export default class Sidebar extends React.Component {
constructor(props) {
super(props);
this.toggleNavbar = this.toggleNavbar.bind(this);
this.state = {
  collapsed: true
};
}
toggleNavbar() {
this.setState({
  collapsed: !this.state.collapsed
});
}
render() {
return (
  <div className="sidebar">
     <Navbar color="faded" light>
      <NavbarToggler onClick={this.toggleNavbar} className="mr-2" />
      <NavbarBrand href="/" className="mr-auto"></NavbarBrand>
<Collapse isOpen={!this.state.collapsed} navbar>
        <Nav navbar>
          <NavItem>
            <NavLink tag={RouterNavLink} to="/"className="test">Home</NavLink> …
