本文介紹如何在linux系統使用gdbus進行程序，分為服務端和客戶端。總體上是比較簡單的，奈何gdbus的幫助文件實在太簡單，網路上的資料也比較少。希望本文對需要使用gdbus的開發人員有幫助。

第一步，是編寫interface和相應函式的xml檔案（D-Bus introspection XML file），供之後藉助gdbus-codegen來建立服務端和客戶端相應的程式碼。比如：

<?xml version="1.0" encoding="UTF-8" ?>

<node name="/com/alibaba/Building">
	<interface name="com.alibaba.Building.Test">
		<method name="SetVersion">
			<arg name="version" type="s" direction="in" />
		</method>
		<signal name="TestStatus">
			<arg name="status" type="i" />
		</signal>
	</interface>
</node>
 

一，服務端。

有了xml檔案，就可以建立服務端需要的程式碼檔案，使用如下命令：

./gdbus-codegen --generate-c-code=Building Building.xml

使用g_bus_own_name註冊，具體資訊請參考幫助文件

guint
g_bus_own_name (GBusType bus_type,
                const gchar *name,
                GBusNameOwnerFlags flags,
                GBusAcquiredCallback bus_acquired_handler,
                GBusNameAcquiredCallback name_acquired_handler,
                GBusNameLostCallback name_lost_handler,
                gpointer user_data,
                GDestroyNotify user_data_free_func);

其中g_signal_connect的第一引數需要呼叫com_alibaba_building_test_skeleton_new來建立。

這樣服務端的流程就基本好了。下一篇講解一下客戶端如何實現來連線服務端。
