nginx上传进度返回我总是相同的大小和recived

我设置我的nginx静态内容域如下所示：

# static0.mywebsite.com static1.mywebsite.com static2.mywebsite.com static3.mywebsite.com server { # upload limit # upload_limit_rate 10240; # request size limitation client_max_body_size 500m; client_body_buffer_size 64k; # document root root /home/mywebsite/myns-projects/mywebsite_com/static/public/; # index file index index.php; # server name server_name static0.mywebsite.com; # rewrite rules rewrite "^/thumbnail/([A-Za-z0-9]{12})/(.*)/.*$" /index.php?request=thumbnail&unique=$1&parameters=$2 last; # set myns no cache set $myns_no_cache 1; if ($request_uri ~* "/thumbnail\/.*/") { set $myns_no_cache 0; } if ($request_uri ~* "/serve\/.*\.(jpg|gif|png|swf)/") { set $myns_no_cache 0; } if ($request_uri ~* "/serve\/.*\.(jpg|gif|png|swf)/") { set $myns_no_cache 0; } # upload location /upload { # proxy to upstream server proxy_pass http://static0.mywebsite.com; proxy_redirect default; # track uploads track_uploads uploadproxied 10s; # mvc rewrite try_files $uri $uri/ /index.php?request=upload&$args; } # / location / { # expires expires max; # disable etag if_modified_since off; add_header 'Last-Modified' ''; # mvc rewrite try_files $uri $uri/ /index.php?$uri&$args; } # progress location /progress { # report uploads tracked in the 'proxied' zone report_uploads uploadproxied; } # php5-fpm location ~ \.php$ { fastcgi_pass 127.0.0.1:9003; fastcgi_param myns_PATH /home/mywebsite/myns; fastcgi_index index.php; fastcgi_read_timeout 300; include fastcgi_params; fastcgi_intercept_errors on; fastcgi_cache_bypass $myns_no_cache; fastcgi_no_cache $myns_no_cache; fastcgi_cache mynsCACHE; fastcgi_cache_valid any 1h; } # deny access to .htaccess and .user.ini files location ~ /\.[ht|user] { deny all; } # disable access log for better performace use at will # access_log /home/mywebsite/myns-projects/mywebsite_com/logs/static_access.log; access_log off; # logs error_log /home/mywebsite/myns-projects/mywebsite_com/logs/static_error.log; } 

提交响应后，jsonp返回的好，但总是received相同的size 。

• 是否可以直接将file upload到Amazon S3并进行编辑？
• WebDisk与FTP – 什么更好？
• 由于pipe道损坏，无法将多于8GB的file upload到Amazon S3
• Nginx client_body_in_file_only用于file upload性能
• 保护Windows到Linuxfile upload
