smartconfig/esptouch失败原因分析

0

Why does SmartConfig fail?
Here are some probable reasons why SmartConfig might fail:

APP version is not matched with SDK or SmartConfig version.
The router under configuration is a 5 GHz-only router.
Some other API was called during SmartConfig (please do not call any APIs under SmartConfig is done).
When using AT command, do not stop SmartConfig before device gets IP from router.

If the above did not solve your problem, please send us the debug log so that we can analyze the problem.

What is the corresponding version of APP or SDK for a given version of SmartConfig?
If the API smartconfig_start() is called by the user, “SC version: vX.X.X” will be printed out for reference. The related SDK and APP versions for SmartConfig versions are listed below:

sdk v1.2.0 smartconfig v2.4 app v0.3.4.x
sdk v1.3.0 smartconfig v2.5 app v0.3.4.x
sdk v1.3.0 smartconfig v2.5.1 app v0.3.4.x
sdk v1.4.0 smartconfig v2.5.2 app v0.3.4.x
sdk v1.5.0 smartconfig v2.5.3 app v0.3.4.x
sdk v1.5.4 smartconfig v2.5.4 app v0.3.4.x

angular状态管理:ngrx vs ngxs vs akita

0

目前我发现的angular状态管理库有以下三种:

NGRX:https://ngrx.io/

NGXS:https://www.ngxs.io/

Akita:https://netbasal.gitbook.io/akita/

三者的结构机器宣称的优势:

NGRX:

ngrx的就不写了,因为后两者的优势多是相对ngrx的。

JWT

优点:服务器不保存,减轻服务器压力,减轻数据库查询压力,服务器重启后,仍然可以访问

缺点:信息泄露后,其他人就会获得所有权限,服务器端无法让其过期

适用场景:

1.有效期短

2.只被使用一次

结论

JWT不适合用作SSO认证方案
