Log directory is: /root/.tsung/log/20160621-1334
[os_mon] memory supervisor port (memsup): Erlang has closed
[os_mon] cpu supervisor port (cpu_sup): Erlang has closed
其中, 其日志为：/root/.tsung/log/20160621-1334。
4. 查看压测报告
进入其生成压测日志目录，然后生成报表，查看压测结果哈：
cd /root/.tsung/log/20160621-1334
/usr/local/lib/tsung/bin/tsung_stats.pl
echo "open your browser (URL: http://IP:8000/report.html) and vist the report now :))"
/usr/bin/python -m SimpleHTTPServer
app:use(function(req, res, next)
local token = ngx.req.get_headers()["Authorization"]
-- 校验失败，err为错误代码，比如 400
local payload, err = verify_jwt(token)
if err then
res:status(err):send("bad access token reqeust")
return
end
-- 注入进当前上下文中，避免每次从token中获取
req.params.uid = payload.uid
next()
end)
针对具体路径进行设定权限拦截，较粗粒度；比如 /user 只允许已登陆授权用户访问
app:use("/user", function(req, res, next)
if not req.params.uid then
-- 注意，这里没有调用next()方法，请求到这里就截止了，不在匹配后面的路由
res:status(403):send("not allowed reqeust")
else
next() -- 满足以上条件，那么继续匹配下一个路由
end
end)
local function check_token(req, res, next)
if not req.params.uid then
res:status(403):send("not allowed reqeust")
else
next()
end
end
local function check_master(req, res, next)
if not req.params.uid ~= master_uid then
res:status(403):send("not allowed reqeust")
else
next()
end
end
local lor = require("lor.index")
local app = lor()
-- 声明一个group router
local user_router = lor:Router()
-- 假设查看是不需要用户权限的
user_router:get("/feedback", function(req, res, next)
end)
user_router:put("/feedback", check_token, function(req, res, next)
end)
user_router:post("/feedback", check_token, function(req, res, next)
end)
-- 只有管理员才有权限删除
user_router:delete("/feedback", check_master, function(req, res, next)
end)
-- 以middleware的形式将该group router加载进来
app:use("/user", user_router())
......
app:run()
-- todo: support upstream id
api_ctx.matched_upstream = (route.dns_value and
route.dns_value.upstream)
or route.value.upstream
直接替换为下面代码即可解决燃眉之急：
local up_id = route.value.upstream_id
if up_id then
local upstreams = core.config.fetch_created_obj("/upstreams")
if upstreams then
local upstream = upstreams:get(tostring(up_id))
if not upstream then
core.log.error("failed to find upstream by id: " .. up_id)
return core.response.exit(502)
end
if upstream.has_domain then
local err
upstream, err = lru_resolved_domain(upstream,
upstream.modifiedIndex,
parse_domain_in_up,
upstream)
if err then
core.log.error("failed to get resolved upstream: ", err)
return core.response.exit(500)
end
end
if upstream.value.pass_host then
api_ctx.pass_host = upstream.value.pass_host
api_ctx.upstream_host = upstream.value.upstream_host
end
core.log.info("parsed upstream: ", core.json.delay_encode(upstream))
api_ctx.matched_upstream = upstream.dns_value or upstream.value
end
else
api_ctx.matched_upstream = (route.dns_value and
route.dns_value.upstream)
or route.value.upstream
end

单元测试依赖
单元测试代码的执行，会在你提交PR代码后自动执行持续集成行为内执行。
首先，需要本机执行单元测试前，需要提前准备好所需Docker测试实例：
docker run --rm --name consul_1 -d -p 8500:8500 consul:1.7 consul agent -server -bootstrap-expect=1 -client 0.0.0.0 -log-level info -data-dir=/consul/data
docker run --rm --name consul_2 -d -p 8600:8500 consul:1.7 consul agent -server -bootstrap-expect=1 -client 0.0.0.0 -log-level info -data-dir=/consul/data
docker run --rm -d \
-e ETCD_ENABLE_V2=true \
-e ALLOW_NONE_AUTHENTICATION=yes \
-e ETCD_ADVERTISE_CLIENT_URLS=http://0.0.0.0:2379 \
-e ETCD_LISTEN_CLIENT_URLS=http://0.0.0.0:2379 \
-p 2379:2379 \
registry.api.weibo.com/wesync/wbgw/etcd:3.4.9
```yaml
discovery:
consul_kv:
servers:
- "http://127.0.0.1:8500"
- "http://127.0.0.1:8600"
prefix: "upstreams"
skip_keys: # if you need to skip special keys
- "upstreams/unused_api/"
timeout:
connect: 1000 # default 2000 ms
read: 1000 # default 2000 ms
wait: 60 # default 60 sec
weight: 1 # default 1
fetch_interval: 5 # default 3 sec, only take effect for keepalive: false way
keepalive: true # default true, use the long pull way to query consul servers
default_server: # you can define default server when missing hit
host: "127.0.0.1"
port: 20999
metadata:
fail_timeout: 1 # default 1 ms
weight: 1 # default 1
max_fails: 1 # default 1
```
......
The `keepalive` has two optional values:
- `true`, default and recommend value, use the long pull way to query consul servers
- `false`, not recommend, it would use the short pull way to query consul servers, then you can set the `fetch_interval` for fetch interval

其次，安装busybox进行调试
安装一个包含有curl的busybox方便后续调试：
kubectl run busybox-curl --image=yauritux/busybox-curl --command -- sleep 3600
