Nginx文件上传下载实现与文件管理
1.Nginx 上传
- Nginx 依赖包下载
# wget http://www.nginx.org/download/nginx-1.2.2.tar.gzinx
# wget http://www.grid.net.ru/nginx/download/nginx_upload_module-2.2.0.tar.gz
# wget http://nchc.dl.sourceforge.net/project/pcre/pcre/8.37/pcre-8.37.tar.gz
# wget http://zlib.net/zlib-1.2.8.tar.gz
# tar -zxvf nginx-1.2.2.tar.gz -C software
# tar zxvf nginx_upload_module-2.2.0.tar.gz -C software/
# tar zxvf pcre-8.37.tar.gz -C software/
# tar zxvf zlib-1.2.8.tar.gz -C software/
- Nginx Configure
# ./configure --prefix=/usr/local/nginx --add-module=../nginx_upload_module-2.2.0 --with-http_secure_link_module --with-pcre=/home/ubuntu/software/pcre-8.37 --with-zlib=/home/ubuntu/software/zlib-1.2.8
- Nginx Make
# make
make过程中,注意查看过程是否出错
-
- 错误1:
解决:
Openssl 安装
检查是否已安装openssl:
sudo apt-get install openssl
如果没有安装执行以下操作:
sudo apt-get install libssl-dev
sudo apt-get install libssl0.9.8
-
- 错误2:
解决:
Just replace "int result;" by "__attribute__((__unused__)) int result;".
- Nginx Make Install
# make install
- Nginx 配置 upload
修改/usr/local/nginx/conf/nginx.conf
# 上传大小限制(包括所有内容)
client_max_body_size 100m;
# 上传path配置
location /upload {
# 转到后台处理URL
upload_pass /uploadHandle;
# 文件上传以后转交给后端的php代码处理
# 这个位置是否是文章上传成功到指定目录后 戳发后台处理的地址
upload_pass /uploadBackendDispose;
# 临时保存路径
# 可以使用散列
upload_store /tmp/nginx_upload;
# 上传文件的权限,rw表示读写 r只读
upload_store_access user:rw;
# 这里写入http报头,pass到后台页面后能获取这里set的报头字段
upload_set_form_field "${upload_field_name}_name" $upload_file_name;
upload_set_form_field "${upload_field_name}_content_type" $upload_content_type;
upload_set_form_field "${upload_field_name}_path" $upload_tmp_path;
# Upload模块自动生成的一些信息,如文件大小与文件md5值
upload_aggregate_form_field "${upload_field_name}_md5" $upload_file_md5;
upload_aggregate_form_field "${upload_field_name}_size" $upload_file_size;
# 允许的字段,允许全部可以 "^.*$"
#upload_pass_form_field "^submit$|^description$";
upload_pass_form_field "^.*$";
# 每秒字节速度控制,0表示不受控制,默认0
upload_limit_rate 0;
# 如果pass页面是以下状态码,就删除此次上传的临时文件
upload_cleanup 400 404 499 500-505;
}
# 将请求转到后端的地址处理
location /uploadBackendDispose
{
proxy_pass
http://localhost:10000/nginx_file_upload;
}
- Nginx 启动
直接运行sudo /usr/local/nginx/sbin/nginx
- Nginx 上传测试POST
Html代码
<html>
<head>
<title>Test upload</title>
</head>
<body>
<h2>Select files to upload</h2>
<form enctype="multipart/form-data" action="http://52.77.234.86/upload" method="post">
<input type="file" name="file1"><br>
<input type="file" name="file2"><br>
<input type="file" name="file3"><br>
<input type="file" name="file4"><br>
<input type="file" name="file5"><br>
<input type="file" name="file6"><br>
<input type="submit" name="submit111" value="Upload">
<input type="hidden" name="user1" value="value1">
<input type="hidden" name="user2" value="value2">
<input type="hidden" name="user3" value="value3">
</form>
</body>
</html>
可在服务器的/tmp/nginx_upload目录在看到上传的文件
这部分参数为上传到后台的处理参数:
- Nginx 上传文件附带参数特别说明
1. Nginx.conf中设置upload_pass_form_field
# 允许所有的字段
upload_pass_form_field "^.*$";
2. Nginx.conf中设置upload_pass_form_field
在上传表单中增加上传字段
<input type="submit" name="submit111" value="Upload">
<input type="hidden" name="user1" value="value1">
<input type="hidden" name="user2" value="value2">
<input type="hidden" name="user3" value="value3">
3. Nginx回调后台的url可接受到以下参数:
uri:/nginx_file_upload

2.Nginx 下载
- Nginx 配置 download
修改/usr/local/nginx/conf/nginx.conf
server {
listen 20150;
root /tmp/nginx_upload;
}
/tmp/nginx_upload为刚才nginx上传的文件目录,这样就可以实现文件的上传和下载
如果涉及到文件后缀名的问题,可以使用python等脚本语言,接受nginx的上传url,然后对上传的文件进行处理,达到逻辑需求
