响应http响应体的编码

Question

我正在使用okhttp库发送请求来休息api.这是我发送请求的java代码https:

RequestBody body = RequestBody.create(JSON, requestBody);

    Request request = new Request.Builder().url("https://examplesite.com/json/").post(body)
            .addHeader("Accept", "application/json, text/javascript, */*; q=0.01")
            .addHeader("Accept-Encoding", "gzip").addHeader("Accept-Language", "en-US,en;q=0.8,fa;q=0.6,ar;q=0.4")
            .build();

    Response response = client.newCall(request).execute();
    String res = new String(response.body().string().getBytes("UTF-8"));

    System.out.println(res);

该res变量是:?CU8{$???'L?@R?W*?$??b?H?E?l?K?C? 30??}c&,p??q???)+3?R?28???#SC?

上面文字的编码是什么？

这是响应头:

Accept:application/json, text/javascript, */*; q=0.01
Accept-Encoding:gzip, deflate
Accept-Language:en-US,en;q=0.8,fa;q=0.6,ar;q=0.4
Connection:keep-alive
Content-Length:95
Content-Type:application/json

我无法理解响应体的编码是什么.无论何时我通过邮递员在Chrome上发送请求,响应正文是一个普通的json.参加该协议https,我认为okhttp库处理加密和描述数据.

删除这个:

 .addHeader("Accept-Encoding", "gzip")

当你这样做时,你告诉OkHttp你想管理自己的响应压缩.

如果您没有明确配置Accept-Encoding,OkHttp将照顾您.它会将标头添加到请求中,并解压缩响应.
