Question

超时后，以下代码

        @Throws(ApiException::class)
        inline fun <reified R> execute(call: Call<R>): R {
        var response: Response<R>? = null
        try {
            response = call.execute() //line (main.kt:137) THE ONE STACKTRACE POINTS TO!!
        } catch (e: IOException) {
            //SHOULD close connection
            throw ApiException.NetworkError(response?.errorBody()?.string() ?: DEFAULT_REASON, cause = e)
        }
        if (response != null && response.isSuccessful)
            try {
                return response.body()!!
            } catch (e: Exception) {
                response.errorBody()?.close()
            }
            //SHOULD close connection
            throw ApiException.ServiceRespondedNegative(response.errorBody()?.string() ?: DEFAULT_REASON)
        }

抛出

我尝试了try / catch / finally的许多组合 stacktrace指向execute()处的(main.kt:137)方法调用不知道如何以及在何处闭合身体。各地都曾尝试致电raw().close()，string()，还是一样的错误。

答案是

    @Throws(ApiException::class)
    inline fun <reified R> execute(call: Call<R>): R {
    var response: Response<R>? = null
    try {
        response = call.execute() //line (main.kt:137) THE ONE STACKTRACE POINTS TO!!
    } catch (e: IOException) {
        //SHOULD close connection
        throw ApiException.NetworkError(response?.errorBody()?.string() ?: DEFAULT_REASON, cause = e)
    }
    if (response != null && response.isSuccessful)
        try {
            return response.body()!!
        } catch (e: Exception) {
            response.errorBody()?.close()
        }
    else response.close() // something like this line was forgotten.
        //SHOULD close connection
        //throw ApiException.ServiceRespondedNegative(response.errorBody()?.string() ?: DEFAULT_REASON)
    }

改造不会在看起来应该的地方关闭连接
