C#对七牛云的操作
1.配置环境
项目中引用 QiNiu.4.0.dll
在webconfig:
<add key="USER_AGENT" value="qiniu csharp-sdk v6.0.0"/>
<add key="ACCESS_KEY" value=""/>//账号 ---> 密钥AK
<add key="SECRET_KEY" value=""/>//账号 ---> 密钥SK
<add key="RS_HOST" value="http://rs.Qbox.me"/>
<add key="UP_HOST" value="http://up.qiniu.com"/>
<add key="RSF_HOST" value="http://rsf.Qbox.me"/>
<add key="PREFETCH_HOST" value="http://iovip.qbox.me"/>
<add key="API_HOST" value="http://api.qiniu.com"/>
2.创建七牛文件的实体类
public class QiNiuFile{
public string fileUrl { get; set; }
public string fileKey { get; set; }
public string fileMime { get; set; }
public string fileThumbnailUrl { get; set; }
}
3.页 面Html 用的form 提交
