我正在尝试学习React with TypeScript,我似乎一直遇到有点模糊的TS错误。
我在下面的三个文件中编写了代码,编译和运行时工作正常。我只是不断得到TypeScript抛出的这个错误,超级烦人
“类型”{ id:任意;键:任意;“}"缺少类型”ProfileCardProps“的以下属性:登录,名称”
//表格.tsx

import * as React from 'react';
import Axios from 'axios';

export default class Form extends React.Component<any,any>{
  constructor(props: any){
    super(props);
    this.state = { userName: ""};
  }

  handleSubmit = (event: React.FormEvent<EventTarget>): void => {
    event.preventDefault();

   //get request...
    .then(resp => {
        this.props.onSubmit(resp.data);
    console.log(resp.data);
    this.setState({userName: ''});
  };

  public render() {
    return(
      <div>
        <div className="col-sm-12">
          <form onSubmit={this.handleSubmit}>
            <label>Run lookup:<br />
              <input type="text"
                value = {this.state.userName}
                onChange = {(event) => this.setState({userName: event.target.value})}
                placeholder = "Enter Username..." >
              </input>
            </label>

         // This is the line that is throwing the error
        {props.cards.map((card: { id: any; }) => <ProfileCard key={card.id} {...card} />)}
      </div>
    )

export default CardList;

//配置文件列表

当你传递卡片给ProfileCard组件时,它传递4个属性值。

{login: string, name: string, key: number, id: number}

但你的界面只有两个

interface ProfileCardProps{ 
  login: string; 
  name: string; 
}

添加key和id应该可以解决这个问题。

interface ProfileCardProps{ 
  login: string; 
  name: string;
  id:any;
  key: any;
}

这种类型的接口使用要求接口的所有成员都为null

interface ProfileCardProps{ 
  login: string; 
  name: string;
  id?:number; 
}

我已经花了大约一个小时来找出类似的错误信息,终于明白,我忘了导入适当的接口:)也许这将是有帮助的人...
