  - getUserMetadata
```
public Map<String,String> getUserMetadata()
```
    Gets user's customized metadata.
    
    OSS uses x-oss-meta- as the prefix in the http headers to transfer the user's customized metadata. However the key value returned by getUserMetadata does not have the prefix---the prefix is added by SDK automatically. The key is case insensitive and will always be in low case when it's returned from OSS. For example, if the key is MyUserMeta，the key returned by this method will be myusermeta.
    
    返回:
    A Map instance that contains the user's customized metadata.
