Question

我使用/ signup端点创建了一个带有mongoose的节点JS后端来注册用户。现在我用角度前端调用BE。当没有错误时，一切似乎都运行得很好。但是，当我尝试创建一个重复的电子邮件地址（从而生成错误）时，我得到一个HTML格式的响应？我不知道如何处理。我的代码

FE（角度5）：

public signUp(data: RegistrationParams): Observable<any> {
    return this._http.post(this._actionUrl, JSON.stringify(data), this._requestOptions)
      .map((response: any) => {
        return JSON.parse(response._body);
      })
      .catch((e) => {
        console.log('error:', e);

      });
  }

这会在错误上记录以下内容：

 <html lang="en">
<head>
<meta charset="utf-8">
<title>Error</title>
</head>
<body>
<pre>Error: something went wrong while adding data to the database E11000 duplicate key error collection: testdb.users index: user.email_1 dup key: { : null }<br> &nbsp; &nbsp;at SignUpController.&lt;anonymous&gt; (/usr/src/app/src/api/v1/SignupController.ts:29:13)<br> &nbsp; &nbsp;at throw (native)<br> &nbsp; &nbsp;at rejected (/usr/src/app/src/api/v1/SignupController.ts:17:65)<br> &nbsp; &nbsp;at process._tickCallback (internal/process/next_tick.js:109:7)</pre>
</body>
</html>

BE（nodeJS）：

@JsonController()
@Service()
export class SignUpController {
  @Post('/signup')
  public async addUser(@Body() body: any, @Res() resp: Response): Promise<T> {
    const newUser = new USER(body);
    try {
      await newUser.save();
      return <DatabaseResponse>{
        successful: true,
        message: 'succes',
      };
    } catch (err) {
      throw new Error('something went wrong while adding data to the database ' + err.message);
    }
  }
}

这只是我尝试抛出错误的方法之一，但一切都在用html响应。那是对的吗？不知道我在这里做错了什么。

您的用户模型可能包含电子邮件字段，请确保唯一字段为false，但不允许重复输入。

email:{
        type:String,
        required:true,
        unique:true,
        trim:true
    }
