java.io.EOFException : End of input at line 1 column 1 path $ in Android retrofit 异常

Question

我正在使用 Retrofit 来使用 REST API 端点，但我遇到了以下问题。我认为 TransactionResponse 类的数据模型有问题，但还不确定。

java.io.EOFException: End of input at line 1 column 1 path $ in Android retrofit

我的调用请求如下。

 @FormUrlEncoded
@POST("/ifapi.php")
Call<TransactionResponse> loadData(@Field("user") TransactionRequest user);

交易请求类:

import javax.annotation.Generated;

@Generated("org.jsonschema2pojo")

public class TransactionResponse {

    private Settings settings;
    /**
     *
     * @return
     * The settings
     */

    public Settings getSettings()
    {
        return settings;
    }
    /**
     *
     * @param settings
     * The settings
     */

    public void setSettings(Settings settings)
    {
        this.settings = settings;
    }

    private Actions actions;
    /**
     *
     * @return
     * The actions
     */
    public Actions getActions()
    {
        return actions;
    }
    /**
     *
     * @param actions
     * The actions
     */
    public void setActions(Actions actions)
    {
        this.actions = actions;
    }
}

下面是调用实际完成的代码。

OkHttpClient httpClient = new OkHttpClient.Builder().build();
Retrofit retrofit = new Retrofit.Builder().addConverterFactory(GsonConverterFactory.create()).baseUrl( 
RestAPI.BASE_URL).client(httpClient).build();
RestAPI service = retrofit.create(RestAPI.class);
Call<TransactionResponse> meResponse = service.loadData(request);

meResponse.enqueue(new Callback<TransactionResponse>() {
       @Override 
       public void onResponse(Call<TransactionResponse> call, Response<TransactionResponse> response) {
               if (response.isSuccessful()) {
                       TransactionResponse body = response.body();
                       Actions actions = body.getActions();
                       Map<String, String> params = actions.getParams();
               }
       }

       @Override
       public void onFailure(Call<TransactionResponse> call, Throwable t){
              t.printStackTrace();
       }
  });

谁能帮帮我？提前致谢。

我正在使用以下库。

compile 'com.squareup.retrofit2:retrofit:2.2.0'
compile 'javax.annotation:javax.annotation-api:1.2'
compile 'com.squareup.retrofit2:converter-gson:2.2.0'

P.S 我发现该请求适用于表单数据，但不适用于 JSON 数据。

我找到了解决方案，您需要以如下形式发布每个参数，而不是在包装类中。

@FormUrlEncoded

@POST("/ifapi.php")

Call<TransactionResponse> loadData(@Field("app_id") String app_id, @Field("install_id") String install_id, @Field("useragent") String useragent, @Field("ip") String ip, @Field("mccmnc") String mccmnc, @Field("action") String action );

对于主要 Activity 部分。

OkHttpClient httpClient = new OkHttpClient.Builder().build();
Gson gson = new GsonBuilder()
                                       .setLenient()
                                       .create();
Retrofit retrofit = new Retrofit.Builder().addConverterFactory(GsonConverterFactory.create(gson)).baseUrl(RestAPI.BASE_URL).client(httpClient).build();

RestAPI service = retrofit.create(RestAPI.class);
Call<TransactionResponse> meResponse = service.loadData("1", getUUID(), getUserAgent(), getIPAddress(), "20404", "start");

希望这能解决您的问题，此致。
