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.

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
