有没有办法使用Web API从ASP.NET网站发送SMS？我知道Web服务,但不知道如何从我的应用程序调用这些服务.

我unexpected token在尝试解析此JSON字符串时遇到错误

我想停止同一用户的多次登录.因此,我创建了一个跟踪已登录用户的表.当他们登录时,数据将输入到表中.当他们点击退出时,数据和会话将被删除.

问题是,当他们关闭浏览器窗口而没有注销时,他们将无法再次登录.

有没有更好的方法来处理这个？

我正在开发一个有 3 种用户的网络应用程序。

为了避免同一用户多次登录，我在表中使用了登录列，登录后该列将变为 1，注销后将变为 0。如果用户关闭浏览器窗口而不注销，我已使用会话状态来注销用户。

<system.web>       
  <sessionState mode="InProc" timeout="15" cookieName="student"/>

全局.asax：

void Session_End(object sender, EventArgs e) 
{
        int sid = Convert.ToInt32(Session["student"]);
        candidate.signoutUser(sid);
}

但用户分为三类。我无法添加多个sessionState. 有办法解决这个问题吗？

我们正在尝试使用动态链接进行深层链接。链接运行正常。

但是，在单击时，它不会命中应用程序中的 userActivity restoreHandler 方法。

我们已按照文档中提到的所有步骤进行操作，诊断结果如下

我正在尝试使用以下代码在我的rails应用程序中保存png

uploader = AvatarUploader.new
uploader.store!(params[:image])

但它抛出了ArgumentError(UTF-8中的无效字节序列)

我在这做错了什么？

我通过使用AFNetworking的ios应用程序发布它.

我正在研究一个简单的绘画应用程序.除了保存,我得到了一切工作.我正在进行面板内的所有油漆操作.我需要将其保存为图像.这该怎么做？
