OSS上传文件

阿里云OSS上传文件，我这是用的老版本的获取OSSClient的方式，因为我们后台没有做OSS的接入，现在新版本的需要后台接入OSS

NSString *endpoint = @"https://oss-cn-hangzhou.aliyuncs.com";

// 移动端建议使用STS方式初始化OSSClient。
id<OSSCredentialProvider> credential = [[OSSFederationCredentialProvider alloc] initWithFederationTokenGetter:^OSSFederationToken * _Nullable{
    OSSFederationToken *token = [OSSFederationToken new];
    // 从STS服务获取的临时访问密钥（AccessKey ID和AccessKey Secret）。
    token.tAccessKey = @"AccessKeyId";
    token.tSecretKey = @"AccessKeySecret";
    // 从STS服务获取的安全令牌（SecurityToken）。
    token.tToken = @"SecurityToken";
    // 临时访问凭证的过期时间。
    token.expirationTimeInGMTFormat = @"Expiration";
    return token;
}];

client = [[OSSClient alloc] initWithEndpoint:endpoint credentialProvider:credential];              

这里的token是需要后台返回的，而且每一次上传文件都需要调用一次后台返回再调用上传的OSS接口，我觉得太麻烦了，还是用的以前的版本的初始化方式，但是其实这种方式是不太安全的，需要安全的话还是用新版本的方式会比较好
