百度广告联盟api probuf协议对接

百度的广告API使用的是不是通常的http协议，而是使用谷歌开源出来的probuf协议，具体介绍请参考：https://www.jianshu.com/p/b1f18240f0c7https://www.jianshu.com/p/b1f18240f0c7

我们对接的客户端使用的是java，所以先会引用相对的jar包，使用的maven，如下：

<dependency>
			<groupId>com.google.protobuf</groupId>
			<artifactId>protobuf-java</artifactId>
			<version>2.5.0</version>
		</dependency>

		<dependency>
			<groupId>org.apache.httpcomponents</groupId>
			<artifactId>httpclient</artifactId>
			<version>4.5.2</version>
		</dependency>
		<dependency>
			<groupId>com.googlecode.protobuf-java-format</groupId>
			<artifactId>protobuf-java-format</artifactId>
			<version>1.2</version>
		</dependency>

　　

需要在windows下载probuf的exe文件，来根据协议生成java的实体class

执行脚本来根据百度提供的 aidu_mobads_api_5.proto 文件生成java类

protoc.exe --java_out=./ baidu_mobads_api_5.proto

会生成一个这个：

然后使用的时候大概是这样：  （会注释掉敏感的）
