[NGINX REFRER:Nginx upload module]
由于tornado通过表达上传的数据最大限制在100M，所以如果需要上传视屏文件的情况在需要通过其他方式实现， 此处采用nginx的nginx-upload-module和jQuery-File-Upload实现。
1.编译安装nginx-upload-module
- 下载nginx-1.5.8
- 下载nginx-upload-module2.0
- 由于nginx-upload-module不支持最新版的nginx，直接编译会出错，需要打补丁 davromaniak.txt
tar xzf nginx-1.5.8
tar xzf nginx_upload_module-2.0.12.tar.gz
cd nginx_upload_moule-2.0.12
patch ngx_http_upload_module.c davromaniak.txt
cd ../nginx-1.5.8
./configure --add-module=../nginx_upload_moule-2.0.12
make & sudo make install2.配置nginx的upload-module

当nginx的upload-module完成视频文件的传输之后，其会设置表单数据，并转发给后台tornado服务器处理。
通过如下方式获得相关参数：
name = self.get_argument("files[].name","")
content_type = self.get_argument("files[].content_type","")
oldpath = self.get_argument("files[].path","")
size = os.path.getsize(oldpath)
files = []
files.append({"name":name,"type":content_type,"size":size})
ret = {"files":files}
self.write(tornado.escape.json_encode(ret))时间： 2024-09-28 22:19:17
