【Android实战】----Android Retrofit2.1.0设置编码格式GBK

来源：互联网发布：干了这碗恒河水知乎编辑：程序博客网时间：2024/06/06 00:53

设置接口如下：

public interface IHttpService {    /**     * 获取userId     * @param params     * @return     */    @FormUrlEncoded    @POST("user/userid.do")    Call<UserIdBean> getUserById(@FieldMap(encoded = true) Map<String, String>params);    /**     * 获取userId     * @param params     * @return     */    @FormUrlEncoded    @POST("user/login.do")    Call<UserBean> login(@FieldMap(encoded = true) Map<String, String>params);}

retrofit中@FormUrlEncoded的默认编码方式为UTF-8，这个没法改变（目前本人所知，如有误请赐教），那么可以通过MediaType进行设置

/**     * 添加统一header,超时时间,http日志打印     * @return     */    public static OkHttpClient genericClient() {        HttpLoggingInterceptor logging = new HttpLoggingInterceptor();        logging.setLevel(HttpLoggingInterceptor.Level.BODY);        OkHttpClient httpClient = new OkHttpClient.Builder()                .addInterceptor(new Interceptor() {                    @Override                    public okhttp3.Response intercept(Chain chain) throws IOException {                        Request request = chain.request();                        Request.Builder requestBuilder = request.newBuilder();                        request = requestBuilder.post(RequestBody.create(MediaType.parse("application/x-www-form-urlencoded;charset=GBK"),                                URLDecoder.decode(bodyToString(request.body()), "UTF-8")))                                .build();                        return chain.proceed(request);                    }                })                .addInterceptor(logging)                .connectTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS)                .writeTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS)                .readTimeout(DEFAULT_TIMEOUT, TimeUnit.SECONDS)                .build();              return httpClient;           }

如上设置了

"application/x-www-form-urlencoded;charset=GBK"

但是request.body()获取到的是已经是经过@FormUrlEncoded编码（UTF-8）过的，因此要先用UTF-8解码，再用GBK编码

bodyToString()的实现

private static String bodyToString(final RequestBody request) {        try {            final RequestBody copy = request;            final Buffer buffer = new Buffer();            if (copy != null)                copy.writeTo(buffer);            else                return "";            return buffer.readUtf8();        } catch (final IOException e) {            return "did not work";        }    }
