android - 无法记录某些行

Question

我的MainActivity的onCreate()包含这部分代码:

    val weatherService = RetrofitFactory.retrofit(AppConstants.OWM_API_URL)
        .create(OwmApi::class.java)
    GlobalScope.launch(Dispatchers.Main) {
        val request = weatherService.getCurrentWeatherDataByName("Bengaluru", "metric")
        Log.i("Response 0", 0.toString())
        try {
            val response = request.await()
            if(response.isSuccessful) {
                Log.i("Response 2", 2.toString())
                val weatherResponse = response.body()
                Log.i("Response 3", 3.toString())
                Log.i("Response", weatherResponse.toString())
                println(weatherResponse)
            }
            else {
                Log.i("Response 5", 5.toString())
                Log.d(TAG, response.errorBody().toString())
            }
        }
        catch (e: Exception) {
            e.stackTrace
        }
    }

weatherService的客户端包含一个拦截器，其定义如下:

private val loggingInterceptor =  HttpLoggingInterceptor().apply {
    level = HttpLoggingInterceptor.Level.BODY
}

现在，当我运行我的应用程序时，我只看到带有 Response 0 标记的日志，但看不到 Response，甚至在我更改时看不到代码的 else 部分查询参数为无效值。也许这与 loggingInterceptor 有关，但我仍然不确定为什么尽管 response.isSuccessful 部分为真，但某些日志消息没有出现。

你必须在后台线程中调用你的 api 调用，可能会出现异常。

所以像下面这样尝试

 val weatherService = RetrofitFactory.retrofit(AppConstants.OWM_API_URL)
    .create(OwmApi::class.java)
GlobalScope.launch(Dispatchers.IO) {
    val request = weatherService.getCurrentWeatherDataByName("Bengaluru", "metric")
    Log.i("Response 0", 0.toString())
    try {
        val response = request.await()
        if(response.isSuccessful) {
            Log.i("Response 2", 2.toString())
            val weatherResponse = response.body()
            Log.i("Response 3", 3.toString())
            Log.i("Response", weatherResponse.toString())
            println(weatherResponse)
        }
        else {
            Log.i("Response 5", 5.toString())
            Log.d(TAG, response.errorBody().toString())
        }
    }
    catch (e: Exception) {
        e.stackTrace
    }
}
