我们试图在鳄梨调味酱上没有认证，但我们遇到了一些麻烦。
在下面，我们遵循的步骤：
通过带有容器的docker安装Guacamole 0.9.8：
使用鳄梨调味酱接口创建鳄梨酱用户。
在下面添加属性时启动文件修改：
set_property“auth-provider”“com.stephensugden.guacamole.net.hmac.HmacAuthenticationProvider”
set_property“secret-key”“xxxxxxxxxxxxxxxx”
set_property“timestamp-age-limit”“600000”
添加清单文件（guac-manifest.json）：
{
"guacamoleVersion" : "0.9.8",
"name" : "HMAC Authentication",
"namespace" : "guac-hmac",
"authProviders" : [
"com.stephensugden.guacamole.net.hmac.HmacAuthenticationProvider"
]
}
使用签名网址和参数调用网址guacamole：
id
timestamp
guac.hostname
guac.protocol
guac.usename
guac.password
guac.port
signature
此调用会在白页上生成。
日志让我登录正确：
15：03：08.026 [http-nio-8080-exec-5] DEBUG o.g.g.n.b.rest.auth.TokenRESTService - 用户登录成功 “0fd88008-26b9-4003-A310-d3408333e871”。
然而，java日志返回：
