實現Nginx Upload 模塊功能上傳文件。

分析（也許我表達的讓人難以理解，可是我想說一句，直接實踐是最好的。。。。。）：php

1、Ningx 上傳（css

1.安裝Nginx 的模塊文件(upload):https://www.nginx.com/resources/wiki/modules/upload/，默認Nginx 確定是沒安裝這個擴展模塊的，你能夠準備刪除Nginx從新去官網下載一個最新穩定版本，而且進行編譯吧。。。。。。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

這裏是扔到10個文件夾裏去
        upload_store /usr/share/nginx/html/file 1;

# Allow uploaded files to be read only by user
        upload_store_access user:r;
就是在這裏，他會自動給你命名。
# 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$|^description$";
    }

這裏是個大坑，由於若是默認就是當前的服務器的80端口，配置這個是會出錯的，我就直接沒用代理，直接

        upload_pass   /upload.php;

#若是是當前端口，設置proxy_pass會出現錯誤 
# Pass altered request body to a backend 
#location @test {
#  proxy_pass htpp://127.0.0.1; 
#}

2.Nginx的某個路由（看我下面的配置文件）檢測到上傳請求後，會分別將各個你定義的form file name，上傳到不一樣的文件夾，一共是10個（建立10個文件夾，命名0 1 2 3 ...），文件位置自定義（但必定要包含那10個文件夾，這個切記），必定要檢測你建立的文件夾Nginx是否具備寫入權限，這個能夠本身看log（這個至關重要），若是你配置完成後想玩點新花樣，能夠本身玩玩，還能夠限制上傳速度之類的，並且能夠作轉發，若是你配置的代理服務器自己就作了URL反向代理，那確定能夠轉發上傳文件到多個Nginx服務器（上傳文件提交信息，好比文件位置在哪兒之類的。）去滴。。。前端

2、直接PHP上傳nginx

PHP上傳文件，自己就要配置Nginx 模塊，因此不少人會搞混，其實二者是有差別的，瀏覽器

正常的上傳流程：html 提交上傳文件，nginx 收到後扔到tmp目錄，PHP收到後，把TMP的上傳文件扔到本身想放的文件夾。bash

-------------------------------------------------------------------服務器

二者都須要編寫HTML，直接提交給Nginx ，在Upload Modules 配置好了，是能夠直接接受多個文件上傳的。php7

<!-- 這是提交給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>
<!-- 這是直接提交給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：經過配置Ningx 安裝 Upload Modules 進行文件上傳再從PHP 接受 Ningx POST過來的參數。app

2.直接經過編寫PHP，從HTML 負責文件上傳

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$|^description$";
    }
#若是是當前端口，設置proxy_pass會出現錯誤
# 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;
    }
}

而後貼上Demo PHP 代碼：

<?php
header('Content-Type: text/html;charset=UTF-8');
//文件後綴=>文件類型
$type = ['.pdf' => 'application/pdf'];

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


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

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

        //判斷文件類型是否存在,文件後綴是咱們本身的key去定義
        if ($fileType = array_search($file['type'], $type)) {

            //以當前的時間命名目錄
            $date_dir = date('Y-m-d', time());

            //若是目錄沒建立,咱們就本身建立一個
            if (!is_dir(FILE_DIR . $date_dir)) {

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

            //文件的MD5+當前unix時間戳+一個5位隨機數,若是此處需求頻繁也能夠用微秒時間戳

            $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('文件大小超出了服務器的空間大小');
        case 2:
            http_response_code(400);
            exit('要上傳的文件大小超出瀏覽器限制');
        case 3:
            http_response_code(400);
            exit('文件僅部分被上傳');
        case 4:
            http_response_code(404);
            exit('沒有找到要上傳的文件');
        case 5:
            http_response_code(503);
            exit('服務器臨時文件夾丟失');
        case 6:
            http_response_code(503);
            exit('文件寫入到臨時文件夾出錯');
    }
}


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

    //判斷文件類型是否存在,文件後綴是咱們本身的key去定義
    if ($fileType = array_search($file['file_content_type'], $type)) {

        //以當前的時間命名目錄
        $date_dir = date('Y-m-d', time());

        //若是目錄沒建立,咱們就本身建立一個
        if (!is_dir(FILE_DIR . $date_dir)) {

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

        //文件的MD5+當前unix時間戳+一個5位隨機數,若是此處需求頻繁也能夠用微秒時間戳

        $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('錯誤操做方式!');
