當我搜索任何標籤時,我正在從instagram api請求數據。作爲回報,我得到了大量的json數據,對應於20張圖片。下面的反應是我以前在網上生成我的POJO塊如何有效地獲取特定的json響應位?

所以,當我這樣做,我得到像10-12不同的POJO類到了我應該映射此數據。現在第一...我只是試圖說出來,我100%生病有一些問題映射他們我的意思是吉森會爲我做的,但我不知道是否有任何更多的,我會需要等等
但最重要的是我的應用程序只需要低標準的url圖片,其他所有信息對我來說都沒用。
Ofcourse,我知道一種方法來做到這一點,它是把整個事情轉換成一個字符串,並通過多次解析整個字符串尋找關鍵詞等等,並製作圖像等我不想這樣做,因爲它的醜陋。它的工作原理,但我想要一個簡潔的方式做到這一點,同時沒有完全映射。
由於您使用Gson基本上有兩個選擇:1.不映射到POJO,只需抓住JSON(Gson有JsonElement); 2.使用流API(Gson也有)。對不起,我通常使用傑克遜,所以我不知道上面兩種情況的代碼,但它應該很容易找到:) – fge
