请先访问 阿里云控制台 创建Bucket，再填写以上内容。

+ 区域 + +

请选择您创建的Bucket所在区域

+
+ AccessKeyId +
+ AccessKeySecret + + +
+ 是否使用内网传输 + + /> +

如果你的服务器是在阿里云并且区域和Bucket所在区域一致，请勾选。

建议不勾选

+
+ 本地文件夹 + + +

附件在服务器上的存储位置，例如： wp-content/uploads （注意不要以“/”开头和结尾），根目录请输入.。

+
+ URL前缀 + + + +

注意：

+ +

1）URL前缀的格式为 {OSS外网访问Bucket域名}/{本地文件夹} ，“本地文件夹”务必与上面保持一致（结尾无 / ），或者“本地文件夹”为 . 时 {OSS外网访问域名} 。

+ +

2）OSS中的存放路径（即“文件夹”）与上述 本地文件夹 中定义的路径是相同的（出于方便切换考虑）。

+ +

3）如果需要使用 用户域名 ，直接将 {OSS外网访问Bucket域名} 替换为 用户域名 即可。
