阿里雲-對象儲存OSS

最近 須要搞一個阿里雲的文件上傳 手機端主要作了圖片上傳

pod安裝：pod 'AliyunOSSiOS', '~> 2.5.2'

 

主要就是須要四個參數：accessKey secretKey endpoint bucket

 

這四個參數都是在網頁生成的 另外在   頁面 建立accessKey secretKey 的時候換須要短信驗證碼 真心麻煩

 

集成過程當中 主要是要選好endpoint  （其中內網 外網是不同的 第一次弄得時候在這上面搞了半天 原來endpoint弄錯了）

 

最後生成的圖片url由endpoint+bucket（+文件夾名字（若是有的話））+你本身命名的圖片名字  構成的

上代碼

NSString * const AccessKey = @"XXXXXXXXXXXXX";
NSString * const SecretKey = @"XXXXXXXXXXXXX";
NSString * const endPoint = @"XXXXXXXXXXXXX";
NSString * const bucketName = @"XXXXXXXXXXXXX";

static NSString *imageTemp = @"imgTemp";
