小编sup*_*toz的帖子

我只是在做一个GET请求,但是我收到了这个错误:

java.lang.RuntimeException:无法启动活动ComponentInfo {com.example.yomac_000.chargingpoint/com.example.yomac_000.chargingpoint.AllStores}:java.lang.IllegalArgumentException:无法为java.util.List创建转换器

这是因为这行代码:

Call<List<Store>> call = subpriseAPI.listStores(response);

所以我试过这行代码来看看它是什么类型的:

System.out.println(subpriseAPI.listStores(response).getClass().toString());

但后来我得到了同样的错误,所以它不会让我知道它是什么类型.在下面你可以看到我的代码.

StoreService.java:

public class StoreService {

    public static final String BASE_URL = "http://getairport.com/subprise/";
    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .build();

    SubpriseAPI subpriseAPI = retrofit.create(SubpriseAPI.class);
    String response = "";

    public List<Store> getSubprises() {

        Call<List<Store>> call = subpriseAPI.listStores(response);

        try {
            List<Store> listStores = call.execute().body();

            System.out.println("liststore "+ listStores.iterator().next());
            return listStores;
        } catch (IOException e) {
            // handle errors
        }
        return null;
    }
}

SubpriseAPI.java:

public interface SubpriseAPI {
    @GET("api/locations/get")
    Call<List<Store>> listStores(@Path("store") String store); …

我正试图git fetch upstream master从另一个用户的存储库获取最新的提交.但不幸的是,这不起作用.我也试过了git fetch upstream.

工作是什么git pull upstream master,但我不想一直使用它,因为它将始终自动执行合并.

这是我执行时得到的输出git fetch upstream master:

git fetch upstream master
From https://github.com/jchun/nodeSite
 * branch            master     -> FETCH_HEAD

这是我的遥控器:

git remote -v
origin git@github.com:superzaky/nodeSite.git (fetch)
origin git@github.com:superzaky/nodeSite.git (push)
upstream       https://github.com/jchun/nodeSite.git (fetch)
upstream       https://github.com/jchun/nodeSite.git (push)

如何在Thymeleaf中显示包含HTML标记的字符串？

所以这段代码:

<div th:each="content : ${cmsContent}">
    <div class="panel-body" sec:authorize="hasRole('ROLE_ADMIN')">
        <div th:switch="${content.reference}"> 
            <div th:case="'home.admin'">
                <p th:text="${content.text}"></p>
            </div>
        </div>
    </div>

//More code....

在这段代码中,${content.text}它在浏览器上生成了这个:

<p>test</p>

但我想在浏览器上显示:

测试

我收到以下错误: Uncaught TypeError: result.subscribe is not a function

这是错误的屏幕截图:

但我确实试图捕捉错误.您可以在下面看到我的代码.

login.component.ts:

import { Component } from '@angular/core';
import { UserService } from '../../services/user.service';
import { User } from '../../models/user';
import {ToasterContainerComponent, ToasterService, ToasterConfig} from 'angular2-toaster/angular2-toaster';

@Component({
    moduleId: module.id,
    selector: 'login',
    directives: [ToasterContainerComponent],
    templateUrl: 'login.component.html',
    providers: [UserService, ToasterService]
})

export class LoginComponent {
    user: User = new User();
    loginRes: String;
    private toasterService: ToasterService;

    public toasterconfig: ToasterConfig = new ToasterConfig({
        showCloseButton: true,
        tapToDismiss: false,
        timeout: 0
    });

    constructor(private _userService: UserService, toasterService: ToasterService) …

当我点击登录链接时，我会转到/login. 看起来像这个截图链接：

请注意在Session not found发出请求后给予我的 Angular 2 应用程序的响应。检查用户是否登录。这一切都很好。

但是当我刷新页面时，我收到以下错误Cannot GET /login链接到屏幕截图：

为了修复该错误，我在 Express 应用程序中添加了以下内容：

//We use this to avoid the error: Cannot GET /login
//but if we use this, then we can't receive a session on the Angular 2 app..
app.route('/*').get(function(req, res) { 
    return res.sendFile(path.join(__dirname, 'public/index.html')); 
});

现在我可以刷新页面而不会出现错误Cannot GET /login。但现在的问题是我收到以下错误：Unexpected token < in JSON at position 0当我的 Angular 2 应用程序想要检查用户是否登录时。这也是它的屏幕截图：

相反，我应该将错误作为响应 Session not found。但不幸的是，这并没有发生。

这是我的 Express 应用程序的代码：

应用程序.js：

var …

当我在 JUnit（版本 4.12）中运行我的测试来下订单时，我收到以下错误：
