之前做平臺(tái)內(nèi)容發(fā)布審核都是自己構(gòu)建一套違禁詞庫，在代碼中利用詞庫判斷用戶發(fā)布的內(nèi)容，現(xiàn)在可以使用百度ai api完成這個(gè)功能。接下來就簡單說下怎么做吧：
首先打開百度ai 開發(fā)平臺(tái) 注冊一個(gè)賬號
進(jìn)入控制臺(tái)
創(chuàng)建自己的應(yīng)用，獲取apikey 和秘鑰
進(jìn)入文檔頁 文本審核：
圖像審核：
文檔很詳細(xì)，實(shí)現(xiàn)用戶發(fā)布內(nèi)容審核 圖片審核還是很方便簡單的。
我沒有使用官方的sdk，簡單的整合了一下作為練手，以下是我簡單使用php實(shí)現(xiàn)的代碼demo:
