写入某个服务器上的文本文件 [英] Write to a text file that's on some server

问题描述

我正在构建一个程序，该程序连接到我的网站以获取数据.它只需要写文本文件.我的问题是我不知道该在哪里设置用户信息，用户名和密码，以便我的应用程序能够更改文本文件.这是我的代码:

I''m building a program that connects to my site for data. It only needs to write text file. My problem is that I don''t know where I have to set up user information, username and password so that my app would be able to change the text file. Here is my code:

Uri uri = new Uri("website");
            WebRequest req = WebRequest.Create(uri);
            WebResponse resp = req.GetResponse();
            Stream stream = resp.GetResponseStream();
            StreamWriter sw = new StreamWriter(stream);

            sw.WriteLine("Something...");

            sw.Close();
            stream.Close(); 
            resp.Close();

我知道我可以下载文件，对其进行编辑并比对其进行上传，但是还有什么更好的方法吗?

I know I can download file,edit it and than upload it, but is there any better way?

推荐答案

首先，您需要发送请求；但是你没有那样做.在这种情况下，您需要使用类System.Net.HttpWebRequest，并像实际一样通过工厂方法创建一个实例:
http://msdn.microsoft.com/en-us/library/system.net. webrequest.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/system.net. httpwebrequest.aspx [ ^ ].

您将在上面引用的MSDN文章中找到一些代码示例.

但是最重​​要的是:服务器端应设计为获取请求，并将其解释为创建文件的请求(这是标准的HTTP文件上传)，或根据某些自定义请求修改文件.无论您在服务器端上具有Web Service还是Web站点，它都可以通过这种方式工作.换句话说，您需要一些服务器端编程.因为这是您的站点，所以可以这样做，但是您需要为HTTP服务器配置一些服务器端脚本技术:ASP.NET，PHP，带有Python的WSGI(将其命名).

First of all, you need to send a request; but you are not doing anything like that. In this case, you need to use the class System.Net.HttpWebRequest, create an instance through the factory method as you actually do:
http://msdn.microsoft.com/en-us/library/system.net.webrequest.aspx[^],
http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.aspx[^].

You will find some code samples in the MSDN articles referenced above.

But most important thing is: the server side should be designed to get a request and interpret it as a request for creation of a file (which is a standard HTTP file upload) or modify the file on some custom request. It works this way, no matter if you have a Web Service or a Web site on the server end. In other words, you need some server-side programming. As this is your site, you can do it, but you need some server-side scripting technology configured for your HTTP server: ASP.NET, PHP, WSGI with Python — you name it.

private bool UploadDocumentWebClient(string FileNamePath, string DestinationUrl)
{
    bool returnValue = false;
    
    try
    {
        
        DestinationUrl = DestinationUrl.Replace(" ", "%20");
        WebClient m_webClient = new WebClient();
        m_webClient.Credentials = new NetworkCredential("UserName", "Password", "Domain");
        m_webClient.UploadFile(DestinationUrl, "PUT", FileNamePath);
        returnValue = true;
    }
    catch 
    {
    }
    return returnValue;
}
