分貝的使用改造2，REST API和MongoDB

POST沒有更新，我需要一個簡單的POST方法使用改裝，槽我的REST的API建立在節點，快速和貓鼬，結束了在我Mongolab接待了來自我的Android應用會D b。問題是我沒有得到任何錯誤...不是從改造，也不是從我的後端。但沒有添加到我的分貝。我想在我的項目中添加一個定義爲POJO的'用戶'。我的getall和findbyid方法都能正常工作，所以我必須在發佈時做錯了任何幫助，我們將不勝感激！ :)分貝的使用改造2，REST API和MongoDB

用戶POJO：

public class User { 
@SerializedName("_id") 
@Expose 
private String id; 
@SerializedName("emailaddress") 
@Expose 
private String emailaddress; 
@SerializedName("name") 
@Expose 
private String name; 
@SerializedName("lastName") 
@Expose 
private String lastName; 
@SerializedName("password") 
@Expose 
private String password; 
@SerializedName("vegetarianExperience") 
@Expose 
private Integer vegetarianExperience; 
@SerializedName("familySituation") 
@Expose 
private Integer familySituation; 
@SerializedName("newsletter") 
@Expose 
private boolean newsletter; 
@SerializedName("score") 
@Expose 
private int score; 
@SerializedName("challenges") 
@Expose 
private List<String> challenges = new ArrayList<>(); 
@SerializedName("favoriteRecipes") 
@Expose 
private List<String> favoriteRecipes = new ArrayList<>(); 

public User(String id, String emailaddress, String name, String lastName, 
      String password, Integer vegetarianExperience, Integer familySituation, 
      boolean newsletter, int score, List<String> challenges, List<String> favoriteRecipes) { 
    this.id = id; 
    this.emailaddress = emailaddress; 
    this.name = name; 
    this.lastName = lastName; 
    this.password = password; 
    this.vegetarianExperience = vegetarianExperience; 
    this.familySituation = familySituation; 
    this.newsletter = newsletter; 
    this.score = score; 
    this.challenges = challenges; 
    this.favoriteRecipes = favoriteRecipes; 
} 

/*getters and setters*/ 

}

的usermodel在後臺與貓鼬：

var mongoose = require('mongoose'); 
var Schema  = mongoose.Schema; 
var ObjectId = Schema.ObjectId; 

var UserSchema = new Schema({ 
_id: ObjectId, 
emailaddress: String, 
name: String, 
lastName: String, 
password: String, 
vegetarianExperience: Number, 
familySituation: Number, 
newsletter: Boolean, 
score: Number, 
challenges: [ 
    { 
     type: Schema.ObjectId, ref: 'Challenge' 
    } 
], 
favoriteRecipes: [ 
    { 
     type: Schema.ObjectId, ref: 'Recipe' 
    } 
] 
}); 

module.exports = mongoose.model('User', UserSchema);

我在Java客戶端類：從我的應用程序的創建inputfields

public class RestClient { 

private static ApiInterface apiInterface; 
private static String baseUrl = "http://188.166.128.173:8080/api/" ; 

public static ApiInterface getClient() { 
    if (apiInterface == null) { 

     OkHttpClient okClient = new OkHttpClient(); 
     okClient.interceptors().add(new Interceptor() { 
      @Override 
      public Response intercept(Chain chain) throws IOException { 
       Response response = chain.proceed(chain.request()); 
       return response; 
      } 
     }); 

     Retrofit client = new Retrofit.Builder() 
       .baseUrl(baseUrl) 
       .client(okClient) 
       .addConverterFactory(GsonConverterFactory.create()) 
       .build(); 
     apiInterface = client.create(ApiInterface.class); 
    } 
    return apiInterface; 
} 

public interface ApiInterface { 

    @GET("recipes") 
    Call<List<Recipe>> recipes(); 

    @GET("users") 
    Call<List<User>> userByMail(@Query("emailaddress") String emailaddress); 

    @POST("users") 
    Call<User> registerNewUser(@Body User user); 
} 
}

用戶和調用api的方法：

個

private void registerNewUser(User user) { 
    RestClient.ApiInterface service = RestClient.getClient(); 
    Call<User> registerNewUser = service.registerNewUser(user); 
    registerNewUser.enqueue(new Callback<User>() { 
     @Override 
     public void onResponse(Response<User> response, Retrofit retrofit) { 
      if (response.isSuccess()) { 
       Log.d("MainActivity", "User is gemaakt!!" + response.body()); 
       goToChallengeBoard(); 
      } else { 
       Log.d("Error: ", response.errorBody().toString()); 
      } 
     } 
     @Override 
     public void onFailure(Throwable t) { 
      Log.d("MainActivity", "GOE KAPOT " + t.getMessage()); 
     } 
    }); 
}

我app.js在後端：

var User  = require('./app/models/user'); 

router.route('/users') 

// create a user (accessed at POST http://localhost:8080/api/users) 
.post(function(req, res) { 

    var user = new User(req.body);  // create a new instance of the User model 

    // save the user and check for errors 
    user.save(function(err) { 
     if (err){ 
      return res.send(err); 
     } 

     res.json({ message: 'User created!' }); 
    }); 
}) 

// get all the users (accessed at GET http://localhost:8080/api/users) 
.get(function(req, res) { 
    User.find(function(err, users) { 
     if (err) 
      res.send(err); 

     res.json(users); 
    }); 
});

行，所以我找到了解決辦法！問題是我在User對象的構造函數中給出了null作爲objectID。我認爲這不是問題，因爲在向您的收藏中添加文檔時，mongolab會創建它自己的ID。所以我認爲它會從API中產生。

這不是這樣，所以我需要貓鼬來生成ID。需要編輯指定_id的行：

var User  = require('./app/models/user'); 

router.route('/users') 

// create a user (accessed at POST http://localhost:8080/api/users) 
.post(function(req, res) { 

    var user = new User(); //Not adding the req.body in the constructor 

    user._id = mongoose.Type.ObjectId(); //<-------THIS IS THE SOLUTION 

    //rest of attributes 

    // save the user and check for errors 
    user.save(function(err) { 
     if (err){ 
      return res.send(err); 
     } 

     res.json({ message: 'User created!' }); 
    }); 
}) 

// get all the users (accessed at GET http://localhost:8080/api/users) 
.get(function(req, res) { 
    User.find(function(err, users) { 
     if (err) 
      res.send(err); 

     res.json(users); 
    }); 
});
