今天我想把我的一个项目从我的开发环境转移到我的生产环境。 当我试图通过FTP上传它时,我已经看到几乎110k文件正在更新。 有人能告诉我这是否真的是必需的,或者我是否错过了一些编译功能等来启动和运行它吗? 干杯,费边

问题内容: 我正在创建用于发送邮件的邮件页面。我需要在发送前附加一些文件。我如何使用AJAX做到这一点?最初,我需要将这些文件存储在服务器中,然后必须发送邮件。通过单个发送按钮即可完成这些操作。 问题答案: 检查以下问题: JavaScript文件上传 如何为我的Web应用程序上传类似Gmail的文件? 什么是最好的多文件JavaScript / Flash文件上传器?
我需要从远程位置读取所有文件并将它们发送到另一个服务,如果成功发送,则删除所有文件。我的代码对于单个文件工作正常,但如果我想在循环中读取所有文件,那么代码不会被执行。 请按以下方式查找代码。在RemoteFileReadImpl类中,我试图读取循环中不起作用的文件。在WebClientUtil类中,我将文件发送到另一个服务。返回成功响应后,我想重命名已读取的文件。
我正试图使用阿拉莫菲尔上传文件。使用文件()时,上传效果很好,但是,我似乎不知道如何使用选项? 这是我的测试: 我的状态代码是415? 此外,如何在上传中发送其他参数? 谢啦 编辑 我没有设置正确的内容类型: 仍然不知道如何发送附加参数随上传。
