Retrofit，Volley和HttpURLConnection的响应不同

Question

向服务器发出一个简单请求，给我不同的响应数据。 Volley和HttpURLConnection给出了与我预期相同的响应，但是，当我请求使用翻新时，它给了我完全不同的数据。

请记住，只有当我使用我们的 WIFI 且仅在移动应用程序中时，这种情况才会发生。当我使用浏览器并发出相同的请求时，我得到了预期的数据。

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val alarmManger = getSystemService(Context.ALARM_SERVICE) as AlarmManager
        val intent = Intent(this, AlarmReceiver::class.java)
        val pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0)
        alarmManger.setRepeating(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime(),
                60 * 1000, pendingIntent)


        Thread {
            var conn = URL("$BASE_URL/home").openConnection() as HttpURLConnection
            var inputStream = conn.inputStream

            val br = BufferedReader(InputStreamReader(inputStream))
            var sB = StringBuilder()

            var line = br.readLine();
            if (line != null) {
                sB.append(line)
            }
            print(sB.toString())

        }.start()

        val retrofit = Retrofit.Builder()
                .baseUrl(BASE_URL)
                .build()
        val service = retrofit.create(GitHubService::class.java)
        service.listRepos().enqueue(object : Callback<ResponseBody> {
            override fun onFailure(call: Call<ResponseBody>?, t: Throwable?) {
                println(t)
            }

            override fun onResponse(call: Call<ResponseBody>?, response: Response<ResponseBody>?) {
                println(response?.body())
            }

        })

        val queue = Volley.newRequestQueue(this)
        val stringRequest = StringRequest(Request.Method.GET, BASE_URL + "/home",
                com.android.volley.Response.Listener<String> { response ->

                    println(response)
                },
                com.android.volley.Response.ErrorListener { })
        queue.add(stringRequest)

    }


}



val BASE_URL = "myserviceurl";


interface GitHubService {
    @GET("home")
    fun listRepos(): Call<ResponseBody>
}
