我需要帮助渲染我的数组我想在map函数中创建一个条件.但不知何故,我的转换器不是接受和解析错误这是我的代码:

import { getGroups } from '../../actions/groupActions'
import { refreshToken } from '../../actions/authActions'
import { connect } from 'react-redux'
import _ from 'lodash'
import { Link } from "react-router"

class Group extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      groups: []
    };
  }

  componentWillMount(){
    this.props.getGroups().then(() => {
      console.log('this groups props: ', this.props)
      if(this.props.errors.code === 'UNAUTHORIZED'){
        this.props.refreshToken().then(() => {
          this.props.getGroups()
        })
      }
    })
  }

  render(){

    const groupArr =  _.valuesIn(this.props.groups)

    return (
      <div>
        <h1>Groups</h1>
        <table className="table table-responsive table-bordered table-condensed">
          <thead>
            <tr> …

我是Angular 2的新手,我需要路由部分的帮助.我正在使用http://jasonwatmore.com/post/2016/09/29/angular-2-user-registration-and-login-example-tutorial

我收到了一个错误

导出变量'routing'已经或正在使用来自外部模块"/ home/frank/angular/node_modules/@ angular/core/src/metadata/ng_module"的名称'ModuleWithProviders',但无法命名.

这是我的代码

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule }    from '@angular/forms';
import { HttpModule } from '@angular/http';

// used to create fake backend
import { fakeBackendProvider } from './_helpers/index';
import { MockBackend, MockConnection } from '@angular/http/testing';
import { BaseRequestOptions } from '@angular/http';

import { AppComponent }  from './app.component';
import { routing }        from './app.routing';

import { AlertComponent } from './_directives/index';
import { AuthGuard } from …

我正在尝试使用redux app进行单元测试.所以我需要测试连接的组件,不幸的是我收到了这个错误:

无法读取未定义的属性'contextTypes'我在单元测试中使用酶这是我的组件:

    import React from 'react';
    import TextFieldGroup from '../common/TextFieldGroup';
    import validateInput from '../../server/validations/login';
    import { connect } from 'react-redux';
    import { login } from '../../actions/authActions';

    class LoginForm extends React.Component {
      constructor(props) {
        super(props);
        this.state = {
          username: '',
          password: '',
          errors: {},
          isLoading: false
        };

        this.onSubmit = this.onSubmit.bind(this);
        this.onChange = this.onChange.bind(this);
      }

      isValid() {
        const { errors, isValid } = validateInput(this.state);

        if (!isValid) {
          this.setState({ errors });
        }

        return isValid;
      }

      onSubmit(e) {
        e.preventDefault();
        if (this.isValid()) {
          this.setState({ …

这是我的 API 请求

public IEnumerator Login(string bodyJsonString)
{
    Debug.Log(bodyJsonString);

    UnityWebRequest req = UnityWebRequest.Post("localhost:3000/login", bodyJsonString);
    req.SetRequestHeader("content-type", "application/json");
    yield return req.SendWebRequest();
    if (req.isNetworkError || req.isHttpError)
    {
        Debug.Log(req.error);
    }
    else
    {
        Debug.Log("Form upload complete!");
    }

}

它返回错误状态代码 500，并在服务器上返回错误 Unexpected token % in JSON atposition 0","severity

这是我的协程调用

public void submitLogin()
{

    _username = userInputField.GetComponent<InputField>().text;
    _password = passwordInputField.GetComponent<InputField>().text;

    Debug.Log("username" + _username);
    Debug.Log("password" + _password);

    string body = "{'username':'" + _username + "','password','" + _password + "'}";

    //API Call
    authChexi = new Auth();
    StartCoroutine(authChexi.Login(body));
}

如果您对如何处理我的表单有任何想法，请告诉我。谢谢
