警告：propType失败：在`Photo`中未指定必需的prop`data`。检查`withApollo（Photo）`的render方法

Question

因此，上面提到的警告是在组件页面加载时生成的（参见附图）。

在组件声明后明确指定组件的propTypes。

任何人都可以解释这个问题吗？

我的代码如下：

Photo.js

＆＃13;

＆＃13;

ias_fraud_df = ias_fraud_df[ias_fraud_df['Placement Name'].str.contains("»")]

＆＃13;

＆＃13;

＆＃13;

PhotoGrid.js

＆＃13;

＆＃13;

import React from 'react';
import Comments from './Comments';
import CSSTransitionGroup from 'react-addons-css-transition-group';
import { Link } from 'react-router';
import {
  gql,
  graphql,
  withApollo
} from 'react-apollo';
import ApolloClient from 'apollo-client';

class Photo extends React.Component {

incrementQuery (currentID) {

    console.log("like of id= " + currentID + " has been incremented by 1");

    this.props.client.query({
      query: queryB,
      variables: {
        id: currentID,
      },
    });
  }

  render() {
    const { post, i } = this.props;

    return (
      <figure key={i} className="grid-figure">
        <div className='grid-photo-wrap'>
          <Link to={`/view/${post.id}`}>
            <img className='grid-photo' src={post.displaysrc} alt={post.caption} />
          </Link>
          <CSSTransitionGroup transitionName="like" transitionEnterTimeout={500} transitionLeaveTimeout={500}>
            <span key={post.likes} className="likes-heart">{post.likes}</span>
          </CSSTransitionGroup>
        </div>
        <figcaption>
          <p>{post.caption}</p>
          <div className="control-buttons">
            <button onClick={this.incrementQuery.bind(null,i)} className="likes">&hearts; {post.likes}</button>
            <Link to={`/view/${post.id}`} className="button">
              <span className="comment-count">
                <span className="speech-bubble"></span> {(post.comments ? Object.keys(post.comments).length : 0)}
              </span>
            </Link>
          </div>
        </figcaption>
      </figure>
    )
  }
};

Photo.propTypes = {
  client: React.PropTypes.instanceOf(ApolloClient).isRequired,
  query: React.PropTypes.object,
  variables: React.PropTypes.object,
  data: React.PropTypes.shape({
    loading: React.PropTypes.bool.isRequired,
    error: React.PropTypes.bool.isRequired,
    updatePosts: React.PropTypes.object,
  }).isRequired,
}

const queryB = gql`
  mutation updatePosts($id: ID!) {
    updatePosts (id: $id, likes: 1) {
      id
      likes
    }
  }  
  `;

const PhotoWithApollo = withApollo(Photo);

export default PhotoWithApollo;

＆＃13;

＆＃13;

Answer 1

此错误是因为组件endAt()需要Photo的属性名称data。这来自代码：

isRequired

您必须使用指定的形状发送至Photo.propTypes = { data: React.PropTypes.shape({ loading: React.PropTypes.bool.isRequired, error: React.PropTypes.bool.isRequired, updatePosts: React.PropTypes.object, }).isRequired } aproperty Photo。

验证data：withApollo中插入data的内容是什么？如果没有，请验证如何调用导出的组件Photo。应该有类似的东西：

PhotoWithApollo
