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

之前做平臺內容發布審核都是自己構建一套違禁詞庫，在代碼中利用詞庫判斷用戶發布的內容，現在可以使用百度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 開發平臺 注冊一個賬號：

注冊賬號，進入控制臺

創建自己的應用，獲取apikey 和秘鑰

進入文檔頁 文本審核：

圖像審核：

文檔很詳細，實現用戶發布內容審核 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:
圖片描述

    protected $imgUrl = "https://aip.baidubce.com/api/v1/solution/direct/img_censor";//圖片審核url
