在參考七牛官方介面的基礎上，提供 PHP/Java/Python/Go 語言的實現以及執行結果。此外：

1. 程式碼基於各服務端語言的七牛 SDK
2. 【重要】七牛其他使用鑑權 token的介面，和此介面呼叫方式類似。如內容稽核的7個介面，人臉識別3個介面，以圖搜圖等。具體實現可以參考下文的【現學現賣】圖片內容稽核介面
3. 下面的程式碼主要提供接入的參考思路，建議根據需要，除錯成功後再修改整合到自己的程式碼中

【現學現賣】圖片內容稽核介面

實現圖片內容稽核，參考 OCR demo 的程式碼檔案，只需要修改請求 url 和 body，即可呼叫成功，具體如下：

1. 介面規約

   POST /v3/image/censor HTTP/1.1
   Host: ai.qiniuapi.com
   
   Content-Type: application/json
   
   Authorization: Qiniu YnxrxOSvGotRZpqkZnMzl_euuoqRzOKUd6zwbRju:r6a-o2UpBg6A4puIMnkCExH8lE8=
   

2. 核心程式碼

   String url = "http://ai.qiniuapi.com/v3/image/censor";
   String host = "ai.qiniuapi.com";
   
   String body = "{ \"data\": { \"uri\": \"https://mars-assets.qnssl.com/resource/gogopher.jpg\" }, \"params\": { \"scenes\": [ \"pulp\", \"terror\", \"politician\" ] } }";
   
   String contentType = "application/json";
   
   String method = "POST";
   
   String qiniuToken = "Qiniu " + auth.signRequestV2(url, method, body.getBytes(), contentType);
   
   System.out.println(url);
   
   System.out.println(body);
   
   System.out.println(qiniuToken);
   
   StringMap header = new StringMap();
   
   header.put("Host", host);
   
   header.put("Authorization", qiniuToken);
   
   header.put("Content-Type", contentType);
   
   Configuration c = new Configuration(Zone.zone1());
   
   Client client = new Client(c);
   
   Response response = client.post(url, body.getBytes(), header, contentType);
