Reactjs Firebase数据库抛出“；错误：Reference.set失败；

我试图将一组数据推送到我的firebase数据库，但一直返回错误。我一直在尝试不同的修复方法，但没有一种有效

这是错误页面的图片：

如果有人能帮助我，我将永远感激：）

代码：

class App extends Component {
  constructor(props){
    super(props);
    this.addOpportunity = this.addOpportunity.bind(this);
    this.removeOpportunity = this.removeOpportunity.bind(this);

    this.app = firebase.initializeApp(DB_CONFIG);
    this.database = this.app.database().ref().child('opportunities');

    //We are going to setup the React state of our component
    this.state = {
      opportunities: [],
    }
  }

  componentWillMount(){
    const previousOpportunities = this.state.opportunities;

    // Data Snapshot
    this.database.on('child_added', snap => {
      previousOpportunities.push({
        id: snap.key,
        opportunityTitle: snap.val(),
        opportunityCompany: snap.val().opportunityCompany,
        opportunityLocation: snap.val().opportunityLocation,
        opportunityDescription: snap.val().opportunityDescription,
        opportunityLink: snap.val().opportunityLink,
      })

      this.setState({
        opportunities: previousOpportunities
      })
    })

    this.database.on('child_removed', snap => {
      for(var i=0; i < previousOpportunities.length; i++){
        if(previousOpportunities[i].id === snap.key){
          previousOpportunities.splice(i, 1);
      }
    }

    this.setState({
      opportunities: previousOpportunities
    })
  })
}

  addOpportunity(){
    this.database.push().set({opportunityTitle: this.state.newopportunityTitle,
                              opportunityCompany: this.state.newopportunityCompany,
                              opportunityLocation: this.state.newopportunityLocation,
                              opportunityDescription: this.state.newopportunityDescription,
                              opportunityLink: this.state.newopportunityLink});
  }

类应用程序扩展组件{

超级（道具）；
this.addOpportunity=this.addOpportunity.bind（this）；
this.removeOpportunity=this.removeOpportunity.bind（this）；
this.app=firebase.initializeApp（DB_CONFIG）；
this.database=this.app.database（）.ref（）.child（'opportunities'）；
//我们将设置组件的反应状态
此.state={

}
组件willmount（）{
const previousOpportunities=this.state.opportunities；
//数据快照
this.database.on（'child_added'，snap=>{
以前的机会({
id:snap.key，
opportunityTitle:snap.val（），
机会主义公司：snap.val（）。机会主义公司，
opportunityLocation:snap.val（）.opportunityLocation，
opportunityDescription:snap.val（）.opportunityDescription，
opportunityLink:snap.val（）.opportunityLink，
})
这是我的国家({
机遇：以前的机遇
})
})
this.database.on（'child_removed'，snap=>{
对于（var i=0；i

我想你想要的是

这个.state.opportunityTitle

而不是

这个.state.newopportunityTitle

非常感谢Colin！当我做以下事情时，它似乎起了作用：

addOpportunity(newOpportunityTitle, newopportunityCompany, 
newopportunityLocation, newopportunityDescription, newopportunityLink){

this.database.push({opportunityTitle: newOpportunityTitle,
                    opportunityCompany: newopportunityCompany,
                    opportunityLocation: newopportunityLocation,
                    opportunityDescription: newopportunityDescription,
                    opportunityLink: newopportunityLink});

---

}

你能发布你的代码吗？应该现在添加，非常感谢@ColinThanks Colin！当我执行以下操作时，它似乎正在工作：addOpportunity（newOpportunityTitle，newopportunityCompany，newopportunityLocation，newopportunityDescription，newopportunityLink）{this.database.push({opportunityTitle:newOpportunityTitle，opportunityCompany:newopportunityCompany，opportunityLocation:newopportunityLocation，opportunityDescription:newopportunityDescription，opportunityLink:newopportunityLink}）；}酷，如果答案有帮助，请投票，或标记为正确。

addOpportunity(newOpportunityTitle, newopportunityCompany, 
newopportunityLocation, newopportunityDescription, newopportunityLink){

this.database.push({opportunityTitle: newOpportunityTitle,
                    opportunityCompany: newopportunityCompany,
                    opportunityLocation: newopportunityLocation,
                    opportunityDescription: newopportunityDescription,
                    opportunityLink: newopportunityLink});
