Question

我有一个CRUD应用程序，您可以在其中创建版本。用户可以添加版本（版本有版本和说明）这可以通过一个按钮和一些字段来完成，您可以在其中输入详细信息

    <button (click)="addRelease(version.value, description.value)" [disabled]="angForm.pristine || angForm.invalid" class="btn btn-primary">Add</button>

我的addRelease函数：

    addRelease(version, description) {
this.releaseservice.addRelease(version, description);
}

我的服务中的addRelease函数：

    addRelease(version,description) {
const uri = 'http://localhost:4000/releases/add';
const obj = {
  version: version,
  description: description
};
this
  .http
  .post(uri, obj)
  .subscribe(res =>
      console.log('Done'));
}

然后在我的releaseRoutes.js

中

   releaseRoutes.route('/releases/add').post(function (req, res) {
   var release = new Release(req.body);
   release.save()
   .then(item => {
   res.status(200).json({'release': 'release added successfully'});
   })
   .catch(err => {
   res.status(400).send("unable to save to database");
    });
   });

server.js：

   releaseRoutes = require('./expressRoutes/releaseRoutes')
   const app = express();
   app.use('/releases', releaseRoutes);

省略了一些代码以便于阅读。

当我尝试创建新版本时它给出了404错误

    POST http://localhost:4000/releases/add 404 (Not Found)
   core.js:1449 ERROR HttpErrorResponse {headers: HttpHeaders, status: 404,statusText: "Not Found", url: "http://localhost:4000/releases/add", ok: false, …}

我是新手，需要一些解决此错误的帮助，已经坚持了几天

Answer 1

您已在/releases

中定义了app.use('/releases', releaseRoutes);的路线

将releaseRoutes.route('/releases/add')更改为releaseRoutes.route('/add')

无法找到路线/发布/添加
