consul 是 token 进行权限控制, 请支持 consul 的token

[zhouandke]

如果consul开启了ACL, 就必须传入一个token 才能访问里面的数据

代码地址：https://github.com/weibocom/nginx-upsync-module/blob/master/src/ngx_http_upsync_module.c

代码片段：包含【?recurse】

2702行：
{
ngx_sprintf(request, "GET %V?recurse&index=%uL HTTP/1.0\r\nHost: %V\r\n"
"Accept: */*\r\n\r\n",
&upscf->upsync_send, upsync_server->index,
&upscf->upsync_host);
}
 
3795行：
{
ngx_sprintf(request, "GET %V?recurse&index=%uL HTTP/1.0\r\nHost: %V\r\n"
"Accept: */*\r\n\r\n",
&upscf->upsync_send, upsync_server->index,
&upscf->[conf_server.name);](http://192.168.6.120:8090/pages/conf_server.name);)
}

解决办法：把?recurse删除掉，变成

2702行：
{
ngx_sprintf(request, "GET %V&index=%uL HTTP/1.0\r\nHost: %V\r\n"
"Accept: */*\r\n\r\n",
&upscf->upsync_send, upsync_server->index,
&upscf->upsync_host);
}
 
3795行：
{
ngx_sprintf(request, "GET %V&index=%uL HTTP/1.0\r\nHost: %V\r\n"
"Accept: */*\r\n\r\n",
&upscf->upsync_send, upsync_server->index,
&upscf->[conf_server.name);](http://192.168.6.120:8090/pages/conf_server.name);)
}

修改后，将模块编译到nginx中，在upstream中配置如下
Consul开启ACL
upsync domain:8500/v1/kv/upstreams/h5_shop?token=xxxxxxxxxxxxxxxxxxxxxxxxxx&recurse
Consul未开启ACL
upsync domain:8500/v1/kv/upstreams/h5_shop?recurse

已经测试过是OK的
