SAE Python如何搭建本地开发环境
https://www.liaoxuefeng.com/article/00137389260145256f699d538ae4fd3910be06d2753b192000
从零开始这篇文章讲得很清楚，新建好一个python应用后，就可以在上面搭建跟微信公众号的接口了。
使用文章的wxpytest代码，会出现not found错误，不知道什么原因，后来重新找了个文章的例子就可以了。
用get方法验证，用post方法接受发送XML格式的信息

配置微信公众号的时候又出现验证失败，从日志中找到url用浏览器打开，发现提示实名认证未通过，看来这就是原因了。果然，在拍身份证上传后，配置微信公众号就成功了。
接着搭建本地SAE环境，注意必须运行在该目录的git bash下，我之前不知道，在命令行运行dev_server.py总是打开文本，纳闷了好久
$ git clone https://github.com/sinacloud/sae-python-dev-guide.git
$ cd sae-python-dev-guide/dev_server
$ python setup.py install
$ dev_server.py
MySQL config not found: app.py
Start development server on http://localhost:8080
改端口：$ dev_server.py -p 8090
看到廖雪峰文章说本地和SAE上环境代码有些不一样，但我这里用的代码都是可以不用修改
本地代码deploy到新浪上也是通过git bash命令行，刚开始先clone，后来每次都是无脑输入下面三个命令
● 在你应用代码目录里，克隆git远程仓库
● $ git clone https://git.sinacloud.com/wxpy
● 输入您的安全邮箱和密码。
● $ cd wxpy
● 编辑代码并将代码部署到 `origin` 的版本1。
● $ git add .
或者git add . --ignoreremoval
● $ git commit -m 'Init my first app'
● $ git push origin 1
push的时候次次都要输入用户名密码，好烦，我还不知怎么搞，下面这些命令无效啊
$git config --global credential.helper wincred
$git config --global user.email "you@example.com"
$git config --global user.name "Your Name"
有时候报错，是因为我在代码代理上自己编辑了代码，要求用git pull，才能继续deploy
● ![rejected] master->master(fetch first)
● error:failed to push some refs to 'https://github.com/xxx/xxx.git'
git pull
本地上的测试代码,用到reqhelper.py里面的 SavePostResponse function ,其它是不用理会

总结下SAE遇到的坑：
1.一个应用扣了10个云豆，刚开始觉得好乐观，一进账户送了200个，实名认证又送了300个，后来才知道是每天扣10个云豆。。。这样也一个应用只能用一个月而已
2.mysql数据库要收费我预料到，想着自己玩下用sqlite就好了，但自带的sqlite它居然不支持。。。真绝
3.好吧，我不用数据库了，用pandas把取到的数据处理下吧，毕竟官方也说可以在vendor目录下放第三方包的，可是比方说pyquery require lxml库，pandas require numpy,six,pytz，无论我全部拷进vendor目录还是用pip install -t vendor pandas
当把代码deploy去sae后，总是import module报错。
4.这些第三方包太大，上传着居然说我达到限额了，应用空间的5G size实在给了我太乐观的假象。
5.代码管理是可以在线编辑代码的，虽然慢点，但有时候懒得敲命令。可是，原来这样修改应用不生效的，一定要用git bash来deploy.
也没有个手动重启应用的功能，而且这样改还会需要再pull一次才行。
6.sae上使用logging没有用，可以直接用print打印出信息，在日志那里可以看到
写了个travelhelper.py文件用来拿珠海户外网发布的活动，代码在git上，本地测试Ok，无奈SAE上import module错误不知怎样fix
代码放在github上
