1. 包下载

openresty-1.13.6.1下载地址 https://openresty.org/download/openresty-1.13.6.1.tar.gz

nginx-upload-module-2.2由于原作者已经很长时间不更新了，本来从原作者github下载的时候，编译openresty的时候报错：ngx_http_upload_module.c:14:17: fatal error: md5.h: No such file or directory

后来找到一个可用的fork版本https://github.com/Austinb/nginx-upload-module

2. 编译

（1）分别解压openresty-1.13.6.1.tar.gz和nginx-upload-module-2.2.zip

（2）执行/sdf/slb/openresty-1.13.6.1# ./configure --prefix=/sdf/slb/openresty --add-module=/sdf/slb/nginx_upload_module-2.2.0

3. 配置

3.1 nginx.conf

需要配置upload_pass作为文件上传之后的返回处理，我们本次使用的是golang写的一个简单http服务。

worker_processes  20;

error_log  logs/error.log notice;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    server {
        listen       8081;
        client_max_body_size 100m;

        # Upload form should be submitted to this location
        location /upload {文件上传的action
            # Pass altered request body to this location
            upload_pass /test/my;文件上传之后的返回

            # Store files to this directory
            # The directory is hashed, subdirectories 0 1 2 3 4 5 6 7 8 9 should exist
            upload_store /sdf/slb/store 1;文件存储的路径，要先手动创建0 1 2 3 4 5 6 7 8 9一共10个文件夹
            
            # Allow uploaded files to be read only by user
            upload_store_access user:rw;

            # Set specified fields in request body
            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;

            # Inform backend about hash and size of a file
            upload_aggregate_form_field "${upload_field_name}_md5" $upload_file_md5;
            upload_aggregate_form_field "${upload_field_name}_size" $upload_file_size;

            upload_pass_form_field "^submit$|^description$";
        }

        # Pass altered request body to a backend
        
        location /test/my {
            proxy_pass http://192.168.25.84:50000;本地一个服务
        }

        location /site {
            root   html;
            index  upload.html;支持文件上传的静态页面
        }
    }
}

本地服务test.go的源代码，运行方式nohup go run test.go &，将启动一个http://127.0.0.1:50000的服务，其中包括一个/test/my的接口，返回upload success字符串。

// test project test.go
package main

import (
	"io"
	"log"
	"net/http"
)

func my(w http.ResponseWriter, r *http.Request) {
	io.WriteString(w, "upload success")
}

func main() {
	http.HandleFunc("/test/my", my)

	err := http.ListenAndServe(":50000", nil)
	if err != nil {
		log.Fatal("Listen Server: ", err.Error())
	}
}

3.2 配置静态页面访问，作为文件上传的入口

搭建openresty静态页面访问，请参考http://www.cnblogs.com/lujiango/p/9001006.html#_lab2_4_0

upload.html的文件内容如下：请注意其中的action="/upload"，与nginx.conf里面的location /upload{}是对应的。

<html>
<head>
<title>Test upload</title>
</head>
<body>
<h2>Select files to upload</h2>
<form enctype="multipart/form-data" action="/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="submit" value="Upload">
<input type="hidden" name="test" value="value">
</form>
</body>
</html>
