下面由WordPress建站教程欄目給大家介紹wordpress rest api的基本使用，希望對需要的朋友有所幫助！
博客開通以來，主要記錄學習和使用過程中遇到的問題及解決方案。文章風格偏向自娛自樂，因此訪問量較少，一臺1核1G的vps足以支撐網站的正常運行。
后來本站引入三個頁面，這三個頁面應該對有上外網需求的網友很有幫助，也給本站帶來了很大的流量。本站用的WordPress程序，嘗試過安裝各種緩存插件（super cache, w3 total cache等）加速運行，但是低配的vps依然難以支持這么大的訪問量。通過日志可以看到隨著訪問量的增加，php-fpm進程增多，Mysql的連接和線程增多，接著出現OOM，然后系統kill掉占用內存最大的Mysql進程，于是網站進入503宕機模式。
買更好的vps能解決訪問量大的問題，但是要花更多的錢。做為一個技術宅，首先想到的當然是如何榨干現有機器來支撐大流量。做過的嘗試包括切換到比WordPress性能更好的Ghost，參考：嘗試Ghost 。但是相對于WordPress，Ghost的生態遠沒有那么成熟，最終放棄了。
左思右想下，終極解決辦法是用Nginx緩存，最初的文章可參考：Nginx配置fastcgi cache。fastcgi_cache的好處是大部分用戶的請求不用后端php-fpm打交道，直接發送緩存的靜態頁面，速度上甩各種WordPress插件好幾條街！相比之下wordpress的各種插件還要執行php，也避免不了訪問數據庫，弱爆了！
自從使用了nginx緩存，網站平穩運行，再也沒有出現過宕機的現象。同時vps的cpu和內存占用率直線下降，再也無需擔心vps的配置問題，感覺再來10倍流量博客也撐得住！
因為nginx穩如狗的體驗，所以現在對于博客類讀多寫少的產品都是強推nginx緩存（fastcgi緩存或者proxy緩存）。鑒于可能幫到一些網友，現貼出 /etc/nginx/nginx.conf 配置文件供網友參考（包含ssl設置和gzip部分）：
