我正在尝试开发短信发送应用程序，但它给出了一个异常“要写入的字节数大于指定的 ContentLength”这是代码
using System;
using Gtk;
using WebKit;
using System.Text;
using System.Net;
using System.IO;
public partial class MainWindow: Gtk.Window
{
byte[] dataout; //global variables
Stream stream = null;
int length;
public MainWindow (): base (Gtk.WindowType.Toplevel)
{
Build ();
requestweb ();
this.DeleteEvent += OnDeleteEvent;
}
private void requestweb() //the post method
{
System.Net.ServicePointManager.ServerCertificateValidationCallback += (s,ce,ca,p) => true;
string index = entryIndex.Text;
string number = entryNumber.Text;
string sms = textviewSMS.Buffer.Text;
string captcha = entryCaptcha.Text;
ASCIIEncoding encoding = new ASCIIEncoding();
string postData = "send=1&smstext=" + sms + "&smstoprefix=" + index + "&smsto=" + number + "&dirtysmstext=" + sms
+ "&translit=on&confirm_key=1&confirmcode=" + captcha + "&x=0&y=0";
byte[] data = encoding.GetBytes (postData);
WebRequest request = WebRequest.Create("https://mobile.beeline.ge/ge/main/sms/send.wbp");
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
stream = request.GetRequestStream();
dataout = data;
length = data.Length;
}
private void addWebView() //load captcha url
{
WebView web = new WebView ();
web.Open ("https://mobile.beeline.ge/ge/main/sms/mamimg.aspx");
web.SetSizeRequest(60,19);
captchaImage.Add (web);
captchaImage.ShowAll ();
}
protected void OnButtonSendClicked (object sender, EventArgs e)
{
SendSMS ();
}
private void SendSMS()
{
stream.Write(dataout, 0, length);
stream.Close();
}
void OnDeleteEvent(object o, DeleteEventArgs args){
Application.Quit();
args.RetVal = true; //this is necessary to stop an error on close.
}
protected void OnButton1Clicked (object sender, EventArgs e)
{
addWebView (); //this loads captcha
}
}
我将发送函数拆分为方法的原因是验证码必须在请求之后和发送之前加载。这是终端输出：
