Source map就是一个信息文件，里面储存着位置信息。也就是说，转换后的代码的每一个位置，所对应的转换前的位置。

有了它，出错的时候，除错工具将直接显示原始代码，而不是转换后的代码。这无疑给开发者带来了很大方便。

1，安装sentry-cli

# npm install -g sentry-cli

2，sentry服务端找到token

直接方式，http://sentry.xxxx.com/api/，下面有token

也可以在主页面的下方去找，不是在左下导行，就在右下。

3，sentry-cli登录

# sentry-cli --url http://sentry.xxxxx.com/ login
This helps you signing in your sentry-cli with an authentication token.
If you do not yet have a token ready we can bring up a browser for you
to create a token now.

Sentry server: sentry.xxxxx.com
Open browser now? [y/n] n
Enter your token:
Enter your token: f6*************************b1
Valid token for user Tank.zhangying@xxxxx.com

Stored token in /root/.sentryclirc

4，上传sourcemap

# sentry-cli releases -o myterm -p electron files staging@1.0.0 upload-sourcemaps /home/test/map
> Analyzing 10 sources
> Adding source map references
> Uploading source maps for release staging@1.0.0

如果报413错误，配置Nginx.conf在http中加上
client_max_body_size 50m;
