Question

我在asp.net网络应用程序中实现了一个弹出窗口，允许用户选择某些内容并生成电子邮件模板。完成所有必填字段后，用户只需点击一下按钮即可发送电子邮件。

此按钮调用javascript函数，我收集所有用户输入数据，如from，to，subject，body，并希望将此数据发送到我创建的将发送邮件的Web服务。

我不想使用mailto，所以我选择了网络服务。

问题在于我无法发送数据：

$.ajax({
            type: 'POST',
            url: "Services/MailService.asmx/SendMail",
            dataType: "json",
            contentType: 'application/json; charset=utf-8',
            data: { 'loginName': "'" + loginName + "'", 'fromAddress': "'" + fromAddress + "'", 'toAddress': "'" + toAddress + "'", 'mailSubject': "'" + mailSubject + "'", 'mailBody': "'" + mailBody + "'"},
            success: function ()
            {
                alert("The email was sent successfully!");
            },
            error: function(data)
            {
                alert("An error occurred while trying to send the email. " + data.responseText);
            }
        });

我知道我在data属性中插入的内容是错误的。我尝试了以下内容（一次一个）：

data: JSON.stringify({ 'loginName': loginName, 'fromAddress': fromAddress, 'toAddress': toAddress, 'mailSubject': mailSubject, 'mailBody': mailBody }),
data: { 'loginName': loginName, 'fromAddress': fromAddress, 'toAddress': toAddress, 'mailSubject': mailSubject, 'mailBody': mailBody },
data: { loginName: loginName, fromAddress: fromAddress, toAddress: toAddress, mailSubject: mailSubject, mailBody: mailBody },
data: "{ 'loginName': '" + loginName + "', 'fromAddress': '" + fromAddress + "', 'toAddress': '" + toAddress + "', 'maliSubject': '" + mailSubject + "', 'mailBody': '" + mailBody + "' }",

所有这些选项都会给我以下错误：

An error occurred while trying to send the email. {"Message":"Invalid web service call, missing value for parameter: \u0027mailBbody\u0027.","StackTrace":"   at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)\r\n   at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

或

An error occurred while trying to send the email. {"Message":"Invalid JSON primitive: loginName.","StackTrace":"   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializePrimitiveObject()\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.DeserializeInternal(Int32 depth)\r\n   at System.Web.Script.Serialization.JavaScriptObjectDeserializer.BasicDeserialize(String input, Int32 depthLimit, JavaScriptSerializer serializer)\r\n   at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.ArgumentException"}

我不明白我做错了什么。

Web服务如下所示：

[System.Web.Script.Services.ScriptService]
public class WebService1 : System.Web.Services.WebService
{
    [WebMethod]
    public void SendMail(string loginName, string fromAddress, string toAddress, string mailSubject, string mailBody)
    {
        MailMessage mailMsg = new MailMessage(fromAddress, toAddress);
        mailMsg.Subject = mailSubject;
        mailMsg.Body = mailBody;

        string pathToCreate = "~/Upload/" + loginName + "/";
        if (Directory.Exists(Server.MapPath(pathToCreate)))
        {
            if (Directory.GetFiles(Server.MapPath(pathToCreate)).Length > 0)
            {
                string[] attachedFiles = Directory.GetFiles(Server.MapPath(pathToCreate));
                foreach (string a in attachedFiles)
                {
                    Attachment data = new Attachment(a);
                    mailMsg.Attachments.Add(data);
                }
            }
        }

        SmtpClient smtp = new SmtpClient();
        smtp.Send(mailMsg);
    }
}

请与我分享我该怎么做才能解决这个问题。

谢谢！

Answer 1

我能够使用以下方式成功发送数据：

data: '{loginName:' + JSON.stringify(loginName) + ', fromAddress:' + JSON.stringify(fromAddress) + ', toAddress:' + JSON.stringify(toAddress) + ', mailSubject:' + JSON.stringify(mailSubject) + ', mailBody:' + JSON.stringify(mailBody) + '}',

我不知道这是不是正确的方式，但它是否有效。

使用ajax从javascript调用Web服务.asmx
