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：

 

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：

     			
      
       com.google.protobuf
      			
      
       protobuf-java
      			
      
       2.5.0
      		
     		
     			
      
       org.apache.httpcomponents
      			
      
       httpclient
      			
      
       4.5.2
      		
     		
     			
      
       com.googlecode.protobuf-java-format
      			
      
       protobuf-java-format
      			
      
       1.2
      		
     

　　

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

在这里下载

 

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）
