nginx 跨域。。。掉坑里了,小心

今天公司產品一個功能突然掛掉了。。。向客戶演示之前出現了，手機端顯示不能獲取下載資源，可是急壞了一票人。。

通過手機端，調查服務器地址調用了http:/2342342.domain.hostname.cn/apis/stickydataurls/接口，服務器返回502和500錯誤，去查看服務器前端Nginx錯誤日志顯示：

2014/08/13 16:11:00 [error] 23851#0: *10303771 connect() failed (111: Connection refused) while connecting to upstream, client: 12.12.12.12, server: *.domain.hostname.cn, request: "POST /apis/pl/getStickGoInfo HTTP/1.0", upstream: "http://10.8.1.10:8080/apis/pl/getStickGoInfo", host: "00e06f26db47.domain.hostname.cn"

這個時候再去看Nginx配置，也沒有錯。對於路徑/  和/apis/stickydataurls/都有重定向，

server_name   *.domain.hostname.cn;
location /{
    ................
}
location = /apis/stickydataurls/ {
    include /etc/nginx/conf.d/PhyLink;
    proxy_pass  http://do.host.cn/apis/pl/getStickGoInfo;
}

但是訪問一直出現問題。
再去查看日志，發現最早的日志，出現了不應該出現的8080端口，這個端口是在 location / 分支才應該出現的，但是在這個配置里邊，出現這個情況是完全不能理解的，手機端調用/apis/stickydataurls/應該進入do.host.cn域下的/apis/pl/getStickGoInfo。而不應該出現10.8.1.10:8080/apis/pl/getStickGoInfo。
