rxjava&retrofit請求直接返回string

1.添加gradle依賴：  
  
compile com.squareup.retrofit2:converter-scalars:2.0.0'  
2.更換轉換器  
mRetrofit = Retrofit.Builder()  
                .baseUrl(HttpAddress.SITE)  
                .addConverterFactory(ScalarsConverterFactory.create())  
                .build();  
3.定義返回類型爲string  
  
new Callback<String>() {  
            @Override  
            public void onResponse(Call<String> call, retrofit2.Response<String> response) {  
                Log.d("debug", response.body());  
            }  
  
            @Override  
            public void onFailure(Call<String> call, Throwable t) {  
  
            }  
        }  
注意或者不加轉換器可是Call<ResponseBody>類型必須是ResponseBody
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(HttpMethods.BASE_URL)
// .addConverterFactory(ScalarsConverterFactory.create())
.build();
MovieService service = retrofit.create(MovieService.class);
Call<ResponseBody> call = service.getTopMovie2(0, 20);
call.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {
if (response.isSuccess()) {
Log.i(TAG, "response.isSuccess()");
try {
Log.i(TAG, "onResponse: " + response.body().string());
} catch (IOException e) {
e.printStackTrace();
}
}
}

@Override
public void onFailure(Call<ResponseBody> call, Throwable t) {
Log.i(TAG, "onFailure: " + t.getMessage());
}
});

}

public interface MovieService {
@GET("top250")
rx.Observable<HttpResult<List<Subject>>> getTopMovie(@Query("start") int start, @Query("count") int count);

@GET("top250")
Call<ResponseBody> getTopMovie2(@Query("start") int start, @Query("count") int count);
}


舉例：

Call<ResponseBody> call = ApiFactory.getInstance().getApiService().updateItems2(accessToken, "cart", cart_params);call.enqueue(new Callback<ResponseBody>() {    @Override    public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {        if (response.isSuccessful()) {            LogUtil.i("response.isSuccess()");            try {                String responseStr = response.body().string();                LogUtil.i("onResponse,onResponse=" + responseStr);                JSONObject jsonObject = new JSONObject(responseStr);                LogUtil.i("onResponse,msg=" + jsonObject.getString("msg"));            } catch (Exception e) {                e.printStackTrace();            }        }    }    @Override    public void onFailure(Call<ResponseBody> call, Throwable t) {        LogUtil.i("onResponse,onFailure=" + t.getMessage());    }});
