Question

如何在我同时使用以下代码段作为请求和响应拦截器的同时使用请求和响应拦截器。

用于请求拦截：

@Override public Response intercept(Chain chain) throws IOException {
    Request request = chain.request();
    RequestBody oldBody = request.body();
    if(request.method().equalsIgnoreCase("POST")){
        Buffer buffer = new Buffer();
        oldBody.writeTo(buffer);
        String strOldBody = buffer.readUtf8();
        Log.i(MainActivity.TAG,"original req "+strOldBody);
        MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
        String strNewBody = "data="+Encryption.encryptString(URLDecoder.decode(strOldBody).replace("data=",""));//EncryptionInterceptor.encryptString(strOldBody);

        Log.i(MainActivity.TAG,"strNewBody "+strNewBody);
        RequestBody body = RequestBody.create(mediaType, strNewBody);
        Log.i(MainActivity.TAG,"content type is "+body.contentType().toString());
        Log.i(MainActivity.TAG,"content length is "+String.valueOf(body.contentLength()));
        Log.i(MainActivity.TAG,"method is "+request.method());
        request = request.newBuilder().header("Content-Type", body.contentType().toString())
                .header("Content-Length", String.valueOf(body.contentLength()))
                .method(request.method(), body).build();
    }
    return chain.proceed(request);
}

对于响应拦截器：

 @Override public Response intercept(Chain chain) throws IOException { Request request = chain.request();

    Response response = chain.proceed(request);
    try {
        final String responseString = new String(response.body().bytes() );
        Log.i(MainActivity.TAG, "Response: " + responseString);
        String  newResponseString = Encryption.decryptString(responseString);
        Log.i(MainActivity.TAG, "Response edited: " + newResponseString);
        return  response.newBuilder()
                .body(ResponseBody.create(response.body().contentType(), newResponseString))
                .build();
    }catch (Exception ex){
        return response;
    }
}

@Override
public Response intercept(Chain chain) throws IOException {
    Request request = chain.request();
    RequestBody oldBody = request.body();

    if(request.method().equalsIgnoreCase("POST")){
        Buffer buffer = new Buffer();
        oldBody.writeTo(buffer);

        String strOldBody = buffer.readUtf8();
        Log.i(MainActivity.TAG,"original req "+strOldBody);
        MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
        String strNewBody = "data="+Encryption.encryptString(URLDecoder.decode(strOldBody).replace("data=",""));//EncryptionInterceptor.encryptString(strOldBody);

        Log.i(MainActivity.TAG,"strNewBody "+strNewBody);
        RequestBody body = RequestBody.create(mediaType, strNewBody);

        Log.i(MainActivity.TAG,"content type is "+body.contentType().toString());
        Log.i(MainActivity.TAG,"content length is "+String.valueOf(body.contentLength()));
        Log.i(MainActivity.TAG,"method is "+request.method());

        request = request.newBuilder().header("Content-Type", body.contentType().toString())
        .header("Content-Length", String.valueOf(body.contentLength()))
        .method(request.method(), body).build();
    }


    Response response = chain.proceed(request);
    try {
        final String responseString = new String(response.body().bytes() );

        Log.i(MainActivity.TAG, "Response: " + responseString);

        String  newResponseString = Encryption.decryptString(responseString);

        Log.i(MainActivity.TAG, "Response edited: " + newResponseString);
        return  response.newBuilder()
                .body(ResponseBody.create(response.body().contentType(), newResponseString))
        .build();

      }catch (Exception ex){
            return response;
      }
}
