实现Nginx Upload 模块功能上传文件。

分析（也许我表达的让人难以理解，可是我想说一句，直接实践是最好的。。。。。）：php

1、Ningx 上传（css

1.安装Nginx 的模块文件(upload):https://www.nginx.com/resources/wiki/modules/upload/，默认Nginx 确定是没安装这个扩展模块的，你能够准备删除Nginx从新去官网下载一个最新稳定版本，而且进行编译吧。。。。。。html

# Upload form should be submitted to this location
    location /upload {

# Pass altered request body to this location
        upload_pass   /upload.php;

# Store files to this directory
# The directory is hashed, subdirectories 0 1 2 3 4 5 6 7 8 9 should exist

这里是扔到10个文件夹里去
        upload_store /usr/share/nginx/html/file 1;

# Allow uploaded files to be read only by user
        upload_store_access user:r;
就是在这里，他会自动给你命名。
# 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$|^description$";
    }

这里是个大坑，由于若是默认就是当前的服务器的80端口，配置这个是会出错的，我就直接没用代理，直接

        upload_pass   /upload.php;

#若是是当前端口，设置proxy_pass会出现错误 
# Pass altered request body to a backend 
#location @test {
#  proxy_pass htpp://127.0.0.1; 
#}

2.Nginx的某个路由（看我下面的配置文件）检测到上传请求后，会分别将各个你定义的form file name，上传到不一样的文件夹，一共是10个（建立10个文件夹，命名0 1 2 3 ...），文件位置自定义（但必定要包含那10个文件夹，这个切记），必定要检测你建立的文件夹Nginx是否具备写入权限，这个能够本身看log（这个至关重要），若是你配置完成后想玩点新花样，能够本身玩玩，还能够限制上传速度之类的，并且能够作转发，若是你配置的代理服务器自己就作了URL反向代理，那确定能够转发上传文件到多个Nginx服务器（上传文件提交信息，好比文件位置在哪儿之类的。）去滴。。。前端

2、直接PHP上传nginx

PHP上传文件，自己就要配置Nginx 模块，因此不少人会搞混，其实二者是有差别的，浏览器

正常的上传流程：html 提交上传文件，nginx 收到后扔到tmp目录，PHP收到后，把TMP的上传文件扔到本身想放的文件夹。bash

-------------------------------------------------------------------服务器

二者都须要编写HTML，直接提交给Nginx ，在Upload Modules 配置好了，是能够直接接受多个文件上传的。php7

<!-- 这是提交给nginx -->
<html lang="CN">
<head>
    <meta charset="UTF-8">
    <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="file"><br>
    <input type="file" name="file1"><br>
    <input type="file" name="file2"><br>

    <input type="submit" name="submit" value="Upload">
    <input type="hidden" name="test" value="value">
</form>
</body>
</html>
<!-- 这是直接提交给php -->
<html lang="CN">
<head>
    <meta charset="UTF-8">
    <title>Test upload</title>
</head>
<body>
<h2>Select files to upload</h2>
<form enctype="multipart/form-data" action="/upload.php" method="post">
    <input type="file" name="file"><br>
    <input type="submit" name="submit" value="Upload">
    <input type="hidden" name="test" value="value">
</form>
</body>
</html>

1：经过配置Ningx 安装 Upload Modules 进行文件上传再从PHP 接受 Ningx POST过来的参数。app

2.直接经过编写PHP，从HTML 负责文件上传

server {
    listen       80;
    server_name  localhost;
charset utf-8;

access_log  /usr/local/nginx/logs/access.log  main;

    client_max_body_size 100m;

# Upload form should be submitted to this location
    location /upload {

# Pass altered request body to this location
        upload_pass   /upload.php;

# Store files to this directory
# The directory is hashed, subdirectories 0 1 2 3 4 5 6 7 8 9 should exist
        upload_store /usr/share/nginx/html/file 1;

# Allow uploaded files to be read only by user
        upload_store_access user:r;

# 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$|^description$";
    }
#若是是当前端口，设置proxy_pass会出现错误
# Pass altered request body to a backend
    #location @test {
    #   proxy_pass   htpp://127.0.0.1;
    #}
    location / {
        root           /usr/share/nginx/html/work/public;
        index  index.html index.htm index.php;
    }

    error_page  404              /404.html;

# redirect server error pages to the static page /50x.html
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }


    location ~ \.php$ {
        root           /usr/share/nginx/html/work/public;
        fastcgi_pass   unix:/opt/remi/php70/root/run/lock/php-fcgi.sock;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
    location ~ .*＼.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires       15d;
    }
    location ~ .*＼.(js|css)?$
    {
        expires       1d;
    }
}

本身感觉~~~~~

而后贴上Demo PHP 代码：

<?php
header('Content-Type: text/html;charset=UTF-8');
//文件后缀=>文件类型
$type = ['.pdf' => 'application/pdf'];

const FILE_DIR = '/usr/share/nginx/html/work/';


//若是非nginx upload module 上传文件
if (count(($file = $_FILES['file'])) > 0) {

    if ($file['error'] == 0) {

        //判断文件类型是否存在,文件后缀是咱们本身的key去定义
        if ($fileType = array_search($file['type'], $type)) {

            //以当前的时间命名目录
            $date_dir = date('Y-m-d', time());

            //若是目录没建立,咱们就本身建立一个
            if (!is_dir(FILE_DIR . $date_dir)) {

                if (!mkdir(FILE_DIR . $date_dir)) {
                    return header('location:503.html');
                }
            }

            //文件的MD5+当前unix时间戳+一个5位随机数,若是此处需求频繁也能够用微秒时间戳

            $filename = FILE_DIR . $date_dir . '/' . (md5_file($file['tmp_name']) . time() . rand(9999, 99999)) . $fileType;


            //生成新的文件
            if (rename($file['tmp_name'], $filename)) {

                return header('Location: success.html');

            }

        }
    }

    switch ($file['error']) {
        case 1:
            http_response_code(400);
            exit('文件大小超出了服务器的空间大小');
        case 2:
            http_response_code(400);
            exit('要上传的文件大小超出浏览器限制');
        case 3:
            http_response_code(400);
            exit('文件仅部分被上传');
        case 4:
            http_response_code(404);
            exit('没有找到要上传的文件');
        case 5:
            http_response_code(503);
            exit('服务器临时文件夹丢失');
        case 6:
            http_response_code(503);
            exit('文件写入到临时文件夹出错');
    }
}


//若是是nginx upload module
if (count(($file = $_POST)) > 0) {

    //判断文件类型是否存在,文件后缀是咱们本身的key去定义
    if ($fileType = array_search($file['file_content_type'], $type)) {

        //以当前的时间命名目录
        $date_dir = date('Y-m-d', time());

        //若是目录没建立,咱们就本身建立一个
        if (!is_dir(FILE_DIR . $date_dir)) {

            if (!mkdir(FILE_DIR . $date_dir)) {
                return header('location:503.html');
            }
        }

        //文件的MD5+当前unix时间戳+一个5位随机数,若是此处需求频繁也能够用微秒时间戳

        $filename = FILE_DIR . $date_dir . '/' . (md5_file($file['file_path']) . time() . rand(9999, 99999)) . $fileType;


        //生成新的文件
        if (rename($file['file_path'], $filename)) {

            return header('Location: success.html');

        }
    }
}


http_response_code(400);
exit('错误操做方式!');
