Javascript React中的Axios请求失败

我不确定我在这里做错了什么

我希望主组件将ajax请求方法传递给子组件InputForm，子组件InputForm将返回存储在主组件状态中的结果

class Main extends React.Component {
    constructor( props ){
        super( props );
        this.state = {
            fetching : false,
            repos : {}
        };
        this.getGitHubRepo = this.getGitHubRepo.bind( this );
    }
    getGitHubRepo( user ){
        this.setState({ fetching : true });
        console.log( "form submitted!", user );
        axios.get( user )
            .then(( response ) => {
                console.log( "response =>", response );
            })
            .catch(( error ) => {
                console.log( "error => ", error );
            });
    }
    render(){
        return(
            <div className = "appContainer">
                <InputForm getGitHubRepo = { this.getGitHubRepo } />
            </div>
        );
    }
}



class InputForm extends React.Component{
    constructor( props ){
        super( props );
        this.state = {
            inputValue : "",
        };
        this.recordInput = this.recordInput.bind( this );
    }
    recordInput( e ){
        this.setState({ inputValue : e.target.value });
    }
    render(){
        let getPath = `https://api.github.com/${this.state.inputValue}`;
        return(
            <form onSubmit = {() => this.props.getGitHubRepo( getPath )}>
                <label htmlFor = "user_input">
                    Github Username
                </label>
                <input id = "user_input"
                         type = "input"
                         onChange = { this.recordInput } />
                <input type = "submit" value = "get repos" />
            </form>
        );
    }
}


ReactDOM.render( <Main />, document.getElementById( "app" ));

我没有得到任何结果&我的网页包服务器刷新页面。

这里的主要问题是，您没有在表单提交时调用preventDefault。 另外，获取github repos的url是错误的，但这是次要的

检查更新的jsbin：

谢谢你@Canastro。我没有意识到这一点。

class InputForm extends React.Component{
    constructor( props ){
        super( props );
        this.state = {
            inputValue : "",
        };
        this.recordInput = this.recordInput.bind( this );
        this.submit = this.submit.bind(this);
    }

    recordInput( e ){
        this.setState({ inputValue : e.target.value });
    }

    submit (e) {
      e.preventDefault();
      this.props.getGitHubRepo( `https://api.github.com/users/${this.state.inputValue}/repos` );
    }

    render(){
        return(
            <form onSubmit = {this.submit}>
                <label htmlFor = "user_input">
                    Github Username
                </label>
                <input id = "user_input"
                         type = "input"
                         onChange = { this.recordInput } />
                <input type = "submit" value = "get repos" />
            </form>
        );
    }
}
