摘要：接下來就簡單說下怎么做吧首先打開百度開發(fā)平臺注冊一個賬號注冊賬號，進入控制臺創(chuàng)建自己的應(yīng)用，獲取和秘鑰進入文檔頁文本審核圖像審核文檔很詳細，實現(xiàn)用戶發(fā)布內(nèi)容審核圖片審核還是很方便簡單的。

之前做平臺內(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 注冊一個賬號：

注冊賬號，進入控制臺

創(chuàng)建自己的應(yīng)用，獲取apikey 和秘鑰

進入文檔頁 文本審核：

圖像審核：

文檔很詳細，實現(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，以下是我簡單的代碼demo:
