我正在尝试使用 POST 在 HTTP 服务器上上传文件,但是当我调用它时
uploadFile.Count = 0 amd 不进入 if 语句。文件路径正确。
客户代码
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string fileToUpload = Server.MapPath("~/Files/Ricky_Martin_Livin_la.mp3");
string uploadUrl = "http://localhost/soundcheck/uploadfiles.aspx";
//string uploadUrl = "http://10.0.2.2/musicapp/handle_upload.php";
FileStream rdr = new FileStream(fileToUpload, FileMode.Open);
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(uploadUrl);
req.Method = "POST"; // you might use "POST"
req.ContentLength = rdr.Length;
req.AllowWriteStreamBuffering = true;
Stream reqStream = req.GetRequestStream();
byte[] inData = new byte[rdr.Length];
// Get data from upload file to inData
int bytesRead = rdr.Read(inData, 0, int.Parse(rdr.Length.ToString()));
// put data into request stream
reqStream.Write(inData, 0, int.Parse(rdr.Length.ToString()));
rdr.Close();
req.GetResponse();
// after uploading close stream
reqStream.Close();
}
}

在服务器代码中,我编写这些日志来跟踪哪一行是否有任何错误或错误。
在服务器代码中,它给出 uploadFile.Count = 0 并且不进入 在调试模式下,客户端代码成功执行,但在页面上给出此消息
您可以从服务器/客户端代码中看到.. 不涉及数据库。
