手把手叫你搭建小程序服务端

本例服务端使用的是php，搭建lnmp环境和配置https请查看我的上一篇文章，ubuntu 18.04.5 LTS 安装lnmp

1.下载php版本的腾讯官方小程序demo，wafer2-quickstart-php，解压之后的目录结构，

其中server目录是要部署到自己申请的腾讯云服务器上的，打开server目录，做如下配置，

登录自己的小程序，在开发设置里面查看appId和appSecret，

useQcloudLogin请设置为false，

2.登录自己的服务器，创建存储小程序数据的MySQL库，库名为cAuth，表结构请参考文件cAuth.sql，DB用户名和密码请自行设置，

创建结果，

3. 将server目录打包成server.zip，上传到服务器web目录，我的目录是/var/www/html，解压，然后将目录名修改为weapp（起一个有意义的名字即可）
   
   

4. 配置SDK文件，
   
   这个路径可以自己定，我的路径是/etc/qcloud/sdk.config，内容根据指引设定，
   
   下面是我的设置，仅供参考，
   

5. 修改nginx配置，使小程序demo服务端weapp能够被正常访问，找到nginx配置文件，
   
   下面是我的配置，仅供参考，
   
   nginx配置

# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# https://www.nginx.com/resources/wiki/start/
# https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/
# https://wiki.debian.org/Nginx/DirectoryStructure
#
# In most cases, administrators will remove this file from sites-enabled/ and
# leave it as reference inside of sites-available where it will continue to be
# updated by the nginx packaging team.
#
# This file will automatically load configuration files provided by other
# applications, such as Drupal or Wordpress. These applications will be made
# available underneath a path with that package name, such as /drupal8.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

访问项目weapp，查看服务端部署是否正常，

测试登录服务，看看相应了什么，

这个错误码，表明我们服务端配置正确，接下来要使用客户端联调。

6. 使用微信开发者工具打开小程序demo客户端，修改config.js配置，下面是我的配置，仅供参考，
   
   然后清理缓存，重新编译，
   
   点击测试登录接口，微信授权允许，
   
   测试结果，如果出现了你的头像，请求返回了你的登录信息，表明全链路配置正确，
   

查看DB存储的登录用户信息，

至此，就可以愉快的开发你的小程序了。
