❶ 谁用过fastDFS上传文件，能不能分享点经验
一. 应用系统在上传文件到FastDFS成功时将原始文件名和“文件索引（FID）”保存下来（例如：保存到数据库）。 二. 用户点击下载的时用Nginx的域名和FID拼出url，然后在url后面增加一个参数，指定原始文件名。例如：http://121.14.161.48:9030/group2/M00/00/89/eQ6h3FKJf_PRl8p4AUz4wO8tqaA688.apk?attname=filename.apk 三. 在Nginx上进行如下配置，这样Nginx就会截获url中的参数attname，在Http响应头里面加上字段 Content-Disposition “attachment;filename=$arg_attname”。location /group2/M00 { root /data/store/data; if ($arg_attname ~ "^(.*).apk") { add_header Content-Disposition "attachment;filename=$arg_attname"; } ngx_fastdfs_mole;}12345671234567四. 浏览器发现响应头里面有Content-Disposition “attachment;filename=$arg_attname”时，就会把文件名显示成filename指定的名称。

❸ 初次用fastdfs，请教关于上传文件的问题
faq:9. fdfs_test和fdfs_test1是做什么用的？ 这两个是FastDFS自带的测试程序，会对一个文件上传两次，分别作为主文件和从文件。返回的文件ID也是两个。 并且会上传文件附加属性，storage server上会生成4个文件。
