javascript – JSX / React上的ESLint错误

我正在使用React,这是我的第一次,我需要知道这些错误是什么以及如何解决它

app/app.js
  21:49   error  'socket' is missing in props validation for App  react/prop-types
  22:47   error  'room' is missing in props validation for App    react/prop-types
  23:47   error  'mode' is missing in props validation for App    react/prop-types
  24:47   error  'user' is missing in props validation for App    react/prop-types
  26:32   error  'socket' is missing in props validation for App  react/prop-types
  26:57   error  'room' is missing in props validation for App    react/prop-types
  26:80   error  'mode' is missing in props validation for App    react/prop-types
  26:103  error  'user' is missing in props validation for App    react/prop-types

这是我收到错误的文件

const query = qs.parse(location.search);
const config = {
  socket : query.socket || 'http://10.28.10.85:1101/chat',room   : query.room || 'BJTest',mode   : query.mode || 'player',user   : query.user || 'Alberto',};

class App extends React.Component {

  constructor (props) {
    super(props);
  }

  render () {
    return (<div>
      <div><strong>Socket:</strong> {this.props.socket}</div>
      <div><strong>Room:</strong> {this.props.room}</div>
      <div><strong>Mode:</strong> {this.props.mode}</div>
      <div><strong>User:</strong> {this.props.user}</div>
      <hr />
      <Chat socket={this.props.socket} room={this.props.room} mode={this.props.mode} user={this.props.user} />
    </div>);
  }

}

解决方法

我认为你需要定义在App和Chat组件中使用的proptypes.有关定义,请参见： https://facebook.github.io/react/blog/2015/01/27/react-v0.13.0-beta-1.html#es6-classes.

例：

App.propTypes = {
  socket: React.PropTypes.string.isrequired,room: React.PropTypes.string.isrequired,mode: React.PropTypes.string.isrequired,user: React.PropTypes.string.isrequired
};
