如何在ColdFusion中向客户端发送HTTP状态代码和响应消息？ [英] How can I send HTTP Status Code and a Response messages to the client in ColdFusion?

问题描述

我正在实现单一登录功能。我有一个ColdFusion应用程序，它从Java应用程序（POST请求）获取输入参数。我需要做的是返回状态代码和说明，以指示用户是否可以访问以及如果用户没有访问我的CF应用程序的失败原因。
类似于以下内容：

I am implementing the Single Sign On functionality. I have an ColdFusion application which takes input parameters from Java application (POST request). What I need to do is return status codes and a description to indicate whether the user has access and the failed reason if the user does not have access to my CF application. Something like below:

我创建了一个cfc并将其作为API提供允许Java用户将其UserName，CustomerID传递给我的CF应用程序。
是否需要在同一文件中编写返回响应逻辑？就像抛出错误代码（cfthrow）的函数一样。

I have created a cfc and provided this as an API to allow Java users to pass in their UserName, CustomerID to my CF application. Do I need to write the return response logic in the same file? Like a function which "throw" error code (cfthrow).

或者我可以使用 cfheader...。类似这样：

Or may be I can use "cfheader"....something like this:

<cfif form.CustomerId EQ queryname.CustID>
<CFHEADER 
    STATUSCODE="200"
    STATUSTEXT="Success">

<cfelse>
 <CFHEADER 
    STATUSCODE="400"
    STATUSTEXT="Insufficient Input">
</cfif>

有人可以在这里帮助我吗？

Can anyone please help me here?

推荐答案

您可以使用：

component restpath = "your/rest/path" rest="true"
{
  remote void function errorTest()
    httpmethod = "GET"
    restpath   = ""
  {
    cfheader(
      statuscode = 401,
      statustext = "Invalid Password"
    );

    // or

    restSetResponse({
      status = 401,
      headers = { explanation = "Invalid Password" }
    });

    // or, using Java

    getPageContext()
        .getResponse()
        .getResponse()
        .sendError( JavaCast( 'int', 401 ), "Invalid Password" );

    // or, using the deprecated setStatus(int,string) method in Java

    getPageContext()
        .getResponse()
        .getResponse()
        .setStatus( JavaCast( 'int', 401 ), "Invalid Password" );
  }
}

注意：我没有找到方法可以直接使用 restSetResponse（）设置消息，从而返回带有消息的自定义标头。

Note: I have not found a way to directly set the message using restSetResponse() so this returns a custom header with the message instead.
