如何發送身體使用JSON數據改造android

Question

我想發佈服務器上的JSON數組下。

{ 
    "order": [{ 
      "orderid": "39", 
      "dishid": "54", 
      "quantity": "4", 
      "userid":"2" 
     },{ 
      "orderid": "39", 
      "dishid": "54", 
      "quantity": "4", 
      "userid":"2" 
     }] 

} 

我使用這下面：

private void updateOreder() { 

    M.showLoadingDialog(GetDishies.this); 
    UpdateAPI mCommentsAPI = APIService.createService(UpdateAPI.class); 

    mCommentsAPI.updateorder(jsonObject, new Callback<String>() { 
     @Override 
     public void success(String s, Response response) { 
      M.hideLoadingDialog(); 
      Log.e("ssss",s.toString()); 
      Log.e("ssss", response.getReason()); 
     } 

     @Override 
     public void failure(RetrofitError error) { 
      M.hideLoadingDialog(); 
      Log.e("error",error.toString()); 
     } 

    }); 

} 

我得到以下錯誤：

retrofit.RetrofitError: com.google.gson.JsonSyntaxException: com.google.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true) to accept malformed JSON at line 2 column 6 path $ 

updateApi代碼：

@POST("updateorder.php") 
    void updateorder(@Body JSONObject object,Callback<String>()); 

任何一個可以請你告訴我，我的錯誤？

在此先感謝

使用改裝版2

compile 'com.squareup.retrofit2:retrofit:2.0.0' 
compile 'com.squareup.retrofit:converter-gson:2.0.0-beta2' 

1. 創建對應於JSON結構POJO類，你將發送到服務器：

   public class RequestBody { 
        private List<InnerClass> order; 
   
        public RequestBody(List<InnerClass> order) { 
        this.order = order; 
        } 
   
        public class InnerClass{ 
         private int orderid, dishid, quantity, userid; 
   
         public InnerClass(int orderid, int dishid, int quantity, int userid) { 
         this.orderid = orderid; 
         this.dishid = dishid; 
         this.quantity = quantity; 
         this.userid = userid; 
        } 
        public int getOrderId() { return orderid; } 
        public int getDishId() { return dishid; } 
        public int getQuantity() { return quantity; } 
        public int getUserId() { return userid; } 
        } 
   } 
   

2. 將servicegenerator類創建爲in itialize您Retrofic對象實例：

   public class ServiceGenerator { 
   
       private static OkHttpClient okHttpClient = new OkHttpClient(); 
   
       public static <S> S createService(Class<S> serviceClass) { 
       Retrofit.Builder builder = new Retrofit.Builder() 
             .baseUrl(AppConfig.BASE_URL) 
             .addConverterFactory(GsonConverterFactory.create()); 
       Retrofit retrofit = builder.client(okHttpClient).build(); 
   
       return retrofit.create(serviceClass); 
   } 
   

創建它應該包含 「updateorder」 方法的API服務接口：

public interface ApiService { 
    @POST("updateorder.php") 
    Call<your POJO class that corresponds to your server response data> updateorder(@Body RequestBody object); 
} 

4.inside您的活動或片段，你會喜歡使請求填充您的Json數據並初始化ApiService：

ArrayList<RequestBody.InnerClass> list = new List<>(); 
list.add(new RequestBody.InnerClass(39, 54, 4, 2)); 
list.add(new RequestBody.InnerClass(39, 54, 4, 2)); 
RequestBody requestBody = new RequestBody(list); 

    ApiService apiService = ServiceGenerator.createService(ApiService.class); 
    Call<your POJO class that corresponds to your server response data> call = apiService.updateorder(requestBody); 
//use enqueue for asynchronous requests 
call.enqueue(new Callback<your POJO class that corresponds to your server response data>() { 

    public void onResponse(Response<> response, Retrofit retrofit) { 
     M.hideLoadingDialog(); 
     Log.e("ssss",s.toString()); 
     Log.e("ssss", response.getReason()); 
    } 

    public void onFailure(Throwable t) { 
      M.hideLoadingDialog(); 
      Log.e("error",t.toString()); 
     } 
} 

Answer 2

嘗試修改代碼以改造2

compile 'com.squareup.retrofit2:retrofit:2.0.0' 
compile 'com.squareup.retrofit2:converter-gson:2.0.0' 

您的服務：

@POST("updateorder.php") 
Call<String> updateorder(@Body JsonObject object); 

呼叫改造

Retrofit retrofit = new Retrofit.Builder() 
     .baseUrl(RetrofitService.baseUrl) 
     .addConverterFactory(GsonConverterFactory.create()) 
     .build(); 

使用傳遞您的JSON GSON：

JsonObject postParam = new JsonObject 
postParam.addProperty("order",yourArray) ; 

最後：

Call<String> call = retrofitService.updateorder(postParam); 


    call.enqueue(new Callback<String>() { 
     @Override 
     public void onResponse(Call<String>callback,Response<String>response) { 
      String res = response.body(); 
     } 
      @Override 
      public void onFailure(Call<String> call, Throwable t) { 

      } 
    }); 

我希望能對你有所幫助。

Answer 3

創建OrderRequest類

public class OrderRequest { 

@SerializedName("order") 
public List<Order> orders; 
} 

創建Order類

public class Order { 

    @SerializedName("orderid") 
    public String Id; 
} 

端點

public interface ApiEndpoint{ 
    @POST("order") 
    Call<String> createOrder(@Body OrderRequest order, @HeaderMap HashMap<String,String> headerMap); 
} 

的用途，其中調用服務

在MainActivity這種類型的實現

在createOrder方法中，我們不需要將對象轉換爲Json。因爲當我們進行改造時，我們將轉換器工廠添加爲GsonConverterFactory。它會自動將該對象轉換爲JSON

retrofit = new Retrofit.Builder() 
       .baseUrl(BASE_URL) 
       .addConverterFactory(GsonConverterFactory.create()) 
       .build();
