android開發以上傳圖片到七牛雲緩扮孫存儲伺服器

android開發之上傳圖片到七牛雲缺激存儲伺服器 相信很多開發者會把圖片存放到七牛上，我的web站點也是吧圖片存儲到七牛上，對於以圖片為主的站點，這樣可以節省很大帶寬。 將圖片上傳到七牛伺服器的重點就是獲得上傳憑證uploadToken，直接把AccessKey和Secret放到客戶端太不安全，擾鏈容易被反編譯。所以需要在伺服器端根據AccessKey和Secret動態生成一個uploadToken，

❹ android開發，我想把手機上的數據上傳到網頁上

如果是數據同步,主要還是網路編程
客戶端把數據打包發送到伺服器,然後伺服器解析數據,存儲到資料庫
然後就是你說的在網頁上顯示,這個說白了就是把查詢數據,顯示到前台
通信協議這一塊可以使用TCP或者HTTP,使用HTTP的話還是方便一點如果使用TCP協議,難度可能會大一點,不過有開源的框架(Apache Mina)可以使用
