前言

在使用Retrofit過程中，通過服務(wù)器獲取的數(shù)據(jù)，不一定是標(biāo)準(zhǔn)的json數(shù)據(jù)，當(dāng)時就想能不能有一種方式，可以把數(shù)據(jù)直接獲取到而不是解析好的數(shù)據(jù)

開始實現(xiàn)

主要是實現(xiàn)MediaType，以及responseBodyConverter和requestBodyConverter方法；

public class ToStringConverterFactory extends Converter.Factory {
    private static final MediaType MEDIA_TYPE = MediaType.parse("text/plain");


    @Override
    public Converter<ResponseBody, ?> responseBodyConverter(Type type, Annotation[] annotations, Retrofit retrofit) {
        if (String.class.equals(type)) {
            return new Converter<ResponseBody, String>() {
                @Override
                public String convert(ResponseBody value) throws IOException {
                    return value.string();
                }
            };
        }
        return null;
    }

    @Override public Converter<?, RequestBody> requestBodyConverter(Type type, Annotation[] parameterAnnotations,
            Annotation[] methodAnnotations, Retrofit retrofit) {
        if (String.class.equals(type)) {
            return new Converter<String, RequestBody>() {
                @Override
                public RequestBody convert(String value) throws IOException {
                    return RequestBody.create(MEDIA_TYPE, value);
                }
            };
        }
        return null;
    }
}

開始使用

public interface WechatService {

    @GET("/txapi/weixin/wxhot") Call<String> getHotArticleStr(@Header("apikey") String apiKey,
            @Query("num") int num, @Query("rand") int rand, @Query("word") String word, @Query("page") int page,
            @Query("src") String src);
}

public void getHotArticleRxString(int num, int rand, String word, int page, String src) {
        Retrofit retrofit = new Retrofit
                .Builder()
                .addConverterFactory(new ToStringConverterFactory())
                .baseUrl(baseurl).build();
        WechatService service = retrofit.create(WechatService.class);
        Call<String> resultObser = service.getHotArticleStr(baiduApiKey, num, rand, word, page, src);
        resultObser.enqueue(new Callback<String>() {
            @Override public void onResponse(Call<String> call, Response<String> response) {
                Log.e("jiangcy", "ToStringConverterFactory : " + response.body().toString());
            }

            @Override public void onFailure(Call<String> call, Throwable t) {

            }
        });
    }
