基于Nginx实现文件上传

基于Nginx实现文件上传

需要安装一个nginx-upload-module

下载地址：https://github.com/vkholodkov/nginx-upload-module/tree/2.255

不要使用master，会报错，缺少一个 md5.h

如下便是nginx的配置文件写的很详细了

location /upload
{
        default_type application/json;
        if ($request_method ~* "OPTIONS") {
                return 200 '{"code": -1,"msg": "正在处理中..."}';
        }
        upload_pass   /file/upload/deal; #文件上传完成后nginx将转发如下参数到后台处理

        upload_resumable on; #断点续传
        upload_store /tmp/upload_tmp; #文件保存地址
        upload_limit_rate 500k; #上传限速 0 表示不限速
        upload_store_access user:rw; #临时文件权限
        upload_set_form_field "${upload_field_name}_name" $upload_file_name; #表单name值
        upload_set_form_field "${upload_field_name}_content_type" $upload_content_type; #上传文件的类型
        upload_set_form_field "${upload_field_name}_path" $upload_tmp_path;     #文件上传后保存在服务器上的地址

        upload_aggregate_form_field "${upload_field_name}_md5" $upload_file_md5;        #文件md5
        upload_aggregate_form_field "${upload_field_name}_size" $upload_file_size;      #文件大小

        #upload_pass_form_field "^submit$|^description$";
        upload_pass_form_field "^.*$";  #表单参数
        upload_pass_args on;    #转发参数
        upload_cleanup 400 404 499 500-505; #如果出现这些错误将删除保存的文件
        
}

如果想要查看上传进度，需要安装nginx-upload-progress-module
