改造2：上传图片到服务器，得到奇怪的回应

Question

@POST("/vistek/myservice.php")
    Call<String> send(@Part("myFile") RequestBody file);

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
  HttpLoggingInterceptor interceptor2 = new HttpLoggingInterceptor();
  interceptor2.setLevel(HttpLoggingInterceptor.Level.HEADERS);

  HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
  interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

  httpClient.addInterceptor(interceptor);
  httpClient.addInterceptor(interceptor2);

以及我向服务器发送图像的函数：

public void sendImage(byte[] data)
    {
        MediaType MEDIA_TYPE_JPEG = MediaType.parse("image/jpeg");
        FileUploadService service = ServiceGenerator.createService(FileUploadService.class);

        RequestBody requestBody = RequestBody.create(MEDIA_TYPE_JPEG, data);

        Call<String> call = service.send(requestBody);

        call.enqueue(new Callback<String>() {
            @Override
            public void onResponse(Call<String> call, retrofit2.Response<String> response) {
                Log.d("Upload", "success = " + response.body());
            }

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

                Log.d("Upload","failure: " + t.getMessage());
            }
        });
    }

在调用函数之后，我得到了奇怪的响应，类似于这样：

JFIF C C“

04-12 17:30:11.144 116 69-13785/mmlab.visualsearch d/okhttp:w！1aqaq“2 b#3 r br

当我用Postman测试api时，我的服务器工作正常：

POST /vistek/myservice.php HTTP/1.1
Host: demo.mmlab.uit.edu.vn
Cache-Control: no-cache
Postman-Token: ba965fb1-f7b9-7344-8b8a-ab46095668d1
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW

----WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="myFile"; filename=""
Content-Type: 

----WebKitFormBoundary7MA4YWxkTrZu0gW

请帮助我知道我的代码发生了什么。提前谢了。

这不是奇怪的反应。它是压缩的（gzip）。

似乎您已经在header中添加了“accept-encoding”、“gzip”到请求中。在这种情况下，您有责任解压缩响应。

所以你能做的是：

StringBuilder stringBuilder = new StringBuilder();
ByteArrayInputStream bais = new ByteArrayInputStream(response.body().getBytes());
GZIPInputStream gzis = new GZIPInputStream(bais);
InputStreamReader reader = new InputStreamReader(gzis);
BufferedReader in = new BufferedReader(reader);

String readed;
while ((readed = in.readLine()) != null) {
    stringBuilder.append(readed);
}
in.close();
reader.close();
gzis.close();
String unZippedResponse = stringBuilder.toString();
