阿里云-对象储存OSS

最近 需要搞一个阿里云的文件上传 手机端主要做了图片上传

pod安装：pod 'AliyunOSSiOS', '~> 2.5.2'

主要就是需要四个参数：accessKey secretKey endpoint bucket

这四个参数都是在网页生成的 另外在   页面 创建accessKey secretKey 的时候换需要短信验证码 真心麻烦

集成过程中 主要是要选好endpoint  （其中内网 外网是不一样的 第一次弄得时候在这上面搞了半天 原来endpoint弄错了）

最后生成的图片url由endpoint+bucket（+文件夹名字（如果有的话））+你自己命名的图片名字  构成的

上代码

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

static NSString *imageTemp = @"imgTemp";
