JqueryがWebサービスを呼び出すことができません

Question

Jquery AJAXを使用してWebサービスhttp://www.w3schools.com/webservices/tempconvert.asmxを呼び出そうとしています。

function AppendListItems() { 
      var webMethod = "http://www.w3schools.com/webservices/tempconvert.asmx/CelsiusToFahrenheit"; 
      jQuery.support.cors = true; 
      $.ajax({ 
       type: "POST", 
       contentType: "application/json; charset=utf-8", 
       dataType: "json", 
       url: webMethod, 
       data: { Celsius: "10" }, 
       success: function (msg) { 

        $("#lstPhoneNames").append("<li>" + msg.d + "</li>"); 
       }, 
       error: function (ex, a, b) { 
        alert(b); 
       } 
      }); 

     }; 

しかし、コールはそれはエラーログを返す失敗します

<span><H1>Server Error in '/' Application.<hr width=100% size=1 color=silver></H1> 

      <h2> <i>Runtime Error</i> </h2></span> 

      <font face="Arial, Helvetica, Geneva, SunSans-Regular, sans-serif "> 

      <b> Description: </b>An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. 
      <br><br> 

      <b>Details:</b> To enable the details of this specific error message to be viewable on remote machines, please create a &lt;customErrors&gt; tag within a &quot;web.config&quot; configuration file located in the root directory of the current web application. This &lt;customErrors&gt; tag should then have its &quot;mode&quot; attribute set to &quot;Off&quot;.<br><br> 

      <table width=100% bgcolor="#ffffcc"> 
       <tr> 
        <td> 
         <code><pre> 

&lt;!-- Web.Config Configuration File --&gt; 

&lt;configuration&gt; 
    &lt;system.web&gt; 
     &lt;customErrors mode=&quot;Off&quot;/&gt; 
    &lt;/system.web&gt; 
&lt;/configuration&gt;</pre></code> 

        </td> 
       </tr> 
      </table> 

      <br> 

      <b>Notes:</b> The current error page you are seeing can be replaced by a custom error page by modifying the &quot;defaultRedirect&quot; attribute of the application&#39;s &lt;customErrors&gt; configuration tag to point to a custom error page URL.<br><br> 

      <table width=100% bgcolor="#ffffcc"> 
       <tr> 
        <td> 
         <code><pre> 

&lt;!-- Web.Config Configuration File --&gt; 

&lt;configuration&gt; 
    &lt;system.web&gt; 
     &lt;customErrors mode=&quot;RemoteOnly&quot; defaultRedirect=&quot;mycustompage.htm&quot;/&gt; 
    &lt;/system.web&gt; 
&lt;/configuration&gt;</pre></code> 

        </td> 
       </tr> 
      </table> 

      <br> 

    </body> 

は私がサービス間違った方法を呼び出すのですか？準備ができて文書に追加

Answer 1

挑戦：実際の要求はFiddlerのようないくつかのツールを使用してサーバに送信されるもの

jQuery.support.cors = true; 

Answer 2

チェック。実際に何が必要なのか、送信する内容に違いがあるかもしれません。

Answer 3

ウェブサービスのURLを確認してください。http://www.w3schools.com/webservices/tempconvert.asmx?op=CelsiusToFahrenheitであるべきですか？ OR

http://www.w3schools.com/webservices/tempconvert.asmx?op=FahrenheitToCelsius ??
