前言

在上一篇笔记中已经将 Stack 运行起来了，现在可以着手用 CLI 来做一些测试，第一步是要先登录账户。

小能手这段时间在学习 The Things Network LoRaWAN Stack V3，从使用和代码等角度对该 Stack 进行了分析，详细可点此查看。

1 获取 OAUTH 链接

ubuntu@VM-0-6-ubuntu:~/lorawan-stack$ ./ttn-lw-cli login
  INFO Please go to https://localhost:8885/oauth/authorize?client_id=cli&redirect_uri=http%3A%2F%2Flocalhost%3A11885%2Foauth%2Fcallback&response_type=code
  INFO Waiting for your authorization...

由于这个 Stack 我是跑在 CVM 上，又懒得装桌面系统，所以在本地浏览器访问CVM，将 localhost 做调整。

https://CVM_IP:8885/oauth/authorize?client_id=cli&redirect_uri=http%3A%2F%2Flocalhost%3A11885%2Foauth%2Fcallback&response_type=code

我之前编译有问题，看日志返回了无效的css/js 文件，因此浏览器页面无法展示：

  INFO Request handled                          duration=22.686898ms location=/o

正常顺利的话，我们可以看到登录页面。

2 帐号注册

没有账号的话，需要先注册账号。这边TTN没处理好，WEB没有给与应该有的提示。

我注册时发现无法点击，看了调试日志才发现，原来无法注册“ttn”、“ttn_1”。

  INFO Finished unary call                      duration=268.898µs error=error:p
kg/identityserver/blacklist:blacklisted_id (the ID `ttn` can not be registered)

=ttn.lorawan.v3.UserRegistry namespace=grpc request_id=01D6F5DH4XJ5GVM87YQXRDV25
D

最终是使用 ttn-1 注册成功了。

3 账号登录，网页重定向

本能手在这边经历过一个坑，我把两处 localhost 都做了替换，即 https://CVM_IP:8885/oauth/authorize?client_id=cli&redirect_uri=http%3A%2F%2FCVM_IP%3A11885%2Foauth%2Fcallback&response_type=code

但浏览器立即提示：
HTTP error: urls don’t validate: http://localhost:11885/oauth/callback;/oauth/code / http://CVM_IP:11885/oauth/callback

只能先改一个，https://CVM_IP:8885/oauth/authorize?client_id=cli&redirect_uri=http%3A%2F%2Flocalhost%3A11885%2Foauth%2Fcallback&response_type=code

在出现重定向网页提示无法连接时，再把重定向部分的localhost替换成 CVM_IP。

$ ./ttn-lw-cli login
  INFO Please go to https://localhost:8885/oauth/authorize?client_id=cli&redirect_uri=http%3A%2F%2Flocalhost%3A11885%2Foauth%2Fcallback&response_type=code
  INFO Waiting for your authorization...
  INFO Got OAuth access token
