實現Nginx Upload 模塊 功能上傳文件。


分析(直接實踐是最好的。。。。。):

一、Ningx 上傳(

1.安裝Nginx 的模塊文件(upload):https://www.nginx.com/resources/wiki/modules/upload/,默認Nginx 肯定是沒安裝這個擴展模塊的,你可以准備刪除Nginx重新去官網下載一個最新穩定版本,並且進行編譯吧。。。。。。

 

# 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

這里是扔到10個文件夾里去 upload_store /usr/share/nginx/html/file 1; # Allow uploaded files to be read only by user upload_store_access user:r; 就是在這里,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$"; }
這里是個大坑,因為如果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;
#如果是當前端口,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)檢測到上傳請求后,會分別將各個你定義的form file name,上傳到不同的文件夾,一共是10個(創建10個文件夾,命名0 1  2 3 ...),文件位置自定義(但一定要包含那10個文件夾,這個切記),一定要檢測你創建的文件夾Nginx是否具有寫入權限,這個可以自己看log(這個相當重要),如果你配置完成后想玩點新花樣,可以自己玩玩,還可以限制上傳速度之類的,而且可以做轉發,如果你配置的代理服務器本身就做了URL反向代理,那肯定可以轉發上傳文件到多個Nginx服務器(上傳文件提交信息,比如文件位置在哪兒之類的。)去滴。。。

 

二、直接PHP上傳

PHP上傳文件,本身就要配置Nginx 模塊,所以很多人會搞混,其實兩者是有差異的,

正常的上傳流程:html 提交上傳文件,nginx 收到后 扔到tmp目錄,PHP收到后,把TMP的上傳文件扔到自己想放的文件夾。

 

 

-------------------------------------------------------------------

 

兩者都需要編寫HTML,直接提交給Nginx ,在Upload Modules 配置好了,是可以直接接受多個文件上傳的。

<!-- 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:通過配置Ningx 安裝 Upload Modules 進行 文件上傳 再從PHP 接受 Ningx POST過來的參數。

2.直接通過編寫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$|^description$";
    }
#如果是當前端口,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;
    }
}

  

自己感受~~~~~

 

然后貼上Demo PHP 代碼:

 

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

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


//如果非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,文件后綴是我們自己的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());

            //如果目錄沒創建,我們就自己創建一個
            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,如果此處需求頻繁也可以用微秒時間戳

            $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');
    }
}


//如果是nginx upload module
if (count(($file = $_POST)) > 0) {

    //判斷文件類型是否存在,文件后綴是我們自己的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());

        //如果目錄沒創建,我們就自己創建一個
        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,如果此處需求頻繁也可以用微秒時間戳

        $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('錯誤操作方式!');
