  阿里云部署Java网站和微信开发调试心得技巧(下):https://www.imooc.com/article/20584

一.运行环境搭建(centos上)

  (1) JDK(这里选择的是JDK1.8)    

    下载地址为:http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html选择的是jdk-8u144-linux-x64.rpm。

    下载完成后执行:rpm -ivh jdk-8u144-linux-x64.rpm

  (2) Tomcat 8

    下载地址为http://tomcat.apache.org/download-80.cgi#8.0.46选择的是apache-tomcat-8.0.46.tar.gz

    解压:tar -zxvf apache-tomcat-8.5.41.tar.gz 

      

    启动tomcat:./apache-tomcat-8.5.41/bin/startup.sh

    修改Tomcat默认连接端口(8080):apache-tomcat-8.5.41/conf/server.xml

    修改完成后重启Tomcat:(注意查看端口是否开启或被占用)

      关闭Tomcat服务:./apache-tomcat-8.5.41/bin/shutdown.sh

      启动Tomcat服务:./apache-tomcat-8.5.41/bin/startup.sh

查看Tomcat日志是否启动成功

  (3) Mysql(我用的是Mariadb)repo源,后通过centos自带的yum安装

    下载的地址为https://dev.mysql.com/downloads/repo/yum/这里选择mysql57-community-release-el7-11.noarch.rpm

  (4) Redis(可选,最好预先安装上,这里选择的版本为4.0.2)

    下载地址为https://redis.io/download这里选择。redis-4.0.2.tar.gz。

    解压:tar xzf redis-5.0.5.tar.gz;

    设置redis以支持远程登录:vim redis-5.0.5/redis.conf

    

     还需要给redis.conf添加配置以支持redis作为守护进程一直跑在后台daemonize yes:

      

      注意windows下永久启动redis:

        设置服务命令:redis-server --service-install redis.windows-service.conf --loglevel verbose

        常用redis服务命令:      

          卸载服务:redis-server --service-uninstall

          开启服务:redis-server --service-start

          停止服务:redis-server --service-stop

    安装:cd redis-5.0.5

       make

    启动服务:src/redis-server redis.conf

    redis连接测试:      

      通过redis-cli连接到redis服务器,src/redis-cli,当输入ping 得到pong的回应之后,证明redis配置已经完成     

 

  将上面的软件都下载到本地,并上传到服务器(如果您的系统为MAC或LINUX,直接使用SCP命令行上传,具体指令可以查询网上,如果您的系统为WIN,推荐使用filezilla可视化上传工具上传),或者您也可以直接登录服务器,wget+ftp地址直接下载这些软件;同时需要大家注意的是,我们在服务器上部署了数据库之后,需要往数据库里面去补充数据,我们的线上数据访问的是线上的数据库而非本地的数据库。图片包也需要上传到服务器并通过配置server.xml确保能读取到这些图片(前提是docBase配置上的路径已经在服务器上创建)。

  注:可以利用xshell工具实现远程连接(rz/sz上传下载文件),xftp等工具实现可视化服务器与本地文件传输。

xshell使用

xftp工具使用

 

二.在服务器上发布并运行自己的Java web项目  

  1.将项目打包成War包:

    

  2.打包完成后,将war包上传到服务器上/apache-tomcat-8.5.41/webapps下:

上传成功后,没过几秒tomcat便会在webapps目录下自动从项目war包中解析出项目工程目录来

  3.访问目标Ip和端口成功展示:

    注:可以通过查看IP加端口查看Tomcat是否启动成功,很本机都是一样的。

 

  4.域名解析:

    由于域名比较贵,作为学生党没敢用。以后用的时候简单配置即可。

三.微信开发调试 

  1.登录微信公众平台提交相关信息

    登录微信公总开发平台:https://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login

    【测试号信息】

      appID:开发者ID,是公众号开发识别码,配合开发者密码可以调用微信公众号接口,如获取微信昵称等
      appsecret:开发者密码,是检验公众号开发者身份的密码,具有极高的安全性。切记不要把密码交给第三方开发者或者编写到代码里

    【接口配置信息】


      URL: 是开发者用来接收微信消息和事件的接口URL
      Token:由开发者可以任意填写,用作生成签名(该Token会和接口URL中包含的Token进行比对,从而验证安全性)

      注:在这里需要验证是否来自微信服务器

        微信公众平台开发文档:https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421135319

         配置成功:

    【JS接口安全域名】

      域名:想调用jssdk(如想要通过微信公众号js接口获取地图等工具)必须得填写此域名,在此域名的范围内才能调用jssdk工具,注意这里必须是域名(IP),不是带有http之类的URL

    

    【测试号二维码】

      里面包含了测试号二维码以及已经关注了的用户信息(微信号扫码)

    【体验接口权限表】

      有很多权限可以使用如下:

 


      这里主要介绍【网页服务】里面的【网页帐号】

      网页帐号主要用来设置OAuth2.0里面的网页授权域名,用户在网页授权页同意授权给公众号后,微信会将授权数据传给一个回调页面,回调页面需在此域名下,以确保安全可靠。沙盒号回调地址支持域名和ip,正式公众号回调地址只支持域名。

  2.获取关注此公众号的用户信息(修改后记得重新打包上传到服务器):

      2.1【WechatLoginController】主要用来获取已关注此微信号的用户信息并做相应处理
