今天学了微信开发平台,服务器选用百度的云开发,使用的语言是java。
(1)微信接口验证
在网上找了很多代码,发现之前很多不能用,现将试验成功的记录下来:

选用的是tomcat7 + jdk7环境,部署有两种方式,一种是直接命令行打成ROOT.war , 另外就是新建一个ROOT的文件,下面放WEB-INF这些文件夹。
命令行打war包
将Web应用打包成WAR文件的方法: (1)在命令行中运用Jar命令 假定有一个Web应用:C:/myHome myHome/WEB-INF/…… myHome/files/…… myHome/image/…… myHome/src/…… myHome/index.jsp
在命令行窗口下执行如下命令: C:/>cd myHome
C:/myHome/>jar cvf myhome.war *.*/ .
解释:jar cvf [A->war包名].war [B->资源文件及文件夹] [C->将要生成war包的目标文件夹]
“*.*/”(B->)代表当前目录(C:/myHome)下的所有文件及文件夹。 “.” (C->)表明将要在当前目录中生成war包。
操作完成后,找到C:/myHome下新生成的myhome.war,将其拷入TOMCAT_HOME/webapps/下。然后启动Tomcat即可。
(3)微信提交URL和token 即可成为开发者
