Question

我正在尝试开发短信发送应用，但它提供了一个例外“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send函数拆分为方法的原因是必须在请求之后和发送之前加载验证码。这是终端输出：

请帮忙

Answer 1

您只需获取流request.GetRequestStream()，但不写任何内容。

尝试：

var stream = request.GetRequestStream();
stream.Write(data,0,data.Length);

Answer 2

还有另一种流写入方法

private void SendSMS()
{
    stream.Write(dataout, 0, length);
    stream.Close();
}

Answer 3

您需要在 System.webServer 部分添加此部分代码，转到 Web.config 文件。

<security> 
<requestFiltering> 
<requestLimits maxAllowedContentLength="3000000000" /> 
</requestFiltering> 
</security>
