ColdFusion 10 REST API：如何在没有RestSetResponse（）的情况下设置状态代码201 [英] ColdFusion 10 REST API: How to set status code 201 without RestSetResponse()

问题描述

我正在使用ColdFusion 10的新内置REST API，我想返回状态代码201（已创建）。我首先尝试了在此处描述的RestSetResponse（）方法： http：/ /www.adobe.com/devnet/coldfusion/articles/restful-web-services.html 。除了强制您将函数的returntype设置为 void之外，它的效果很好。 void的问题在于，每当我抛出异常时，它就不再返回正确的JSON错误消息。

I'm using ColdFusion 10's new built-in REST API and I'd like to return a status code of 201 (Created). I first tried the RestSetResponse() approach that's described here: http://www.adobe.com/devnet/coldfusion/articles/restful-web-services.html. It works well, except that it forces you to set the function's returntype to "void". The problem with "void" is that whenever I throw an exception, it no longer returns the proper JSON error message.

抛出此异常：

<cfthrow errorcode="400" message="Validation error." />

当returntype为 struct时，返回格式正确的JSON：

Returns a nicely formatted JSON when the returntype is "struct":

HTTP/1.1 400 Bad Request
Content-Type: application/json

{"Message":"Validation error."}

但是当returntype为 void时（使用RestSetResponse（）是必需的）

But when the returntype is "void" (which is required to use RestSetResponse(), the response is some ugly HTML response.

因此，我不得不恢复使用returntype struct，放弃了RestSetResponse（）并尝试了此操作：

Because of this, I had to revert to using returntype "struct", gave up on RestSetResponse(), and tried this:

<cfheader statusCode="201" statusText="Created" />

但是它不起作用，似乎ColdFusion会覆盖statusCode并在成功时始终返回200（确定）。状态代码为201，而未将函数的返回类型设置为 void？

But it doesn't work. It seems that ColdFusion overwrites the statusCode and always returns 200 (OK) when it's successful. Anyone know of a way to change the status code to 201 without setting the returntype of the function to "void"?

推荐答案

我看不出为什么 restSetResponse（）应该要求返回类型为v oid，但已验证，如果不是这种情况，它将被忽略。

I can't see a good reason why restSetResponse() should require a returntype of void, but have verified it is ignored if this is not the case. Which is a bit rubbish.

我唯一可以通过解决您的情况的方法就是滚动自己的结构，其中包含错误详细信息，然后将其用作为 restSetResponse（）调用设置的 content 值。

The only thing I can think by way of working around your situation is to roll-your-own struct with the error detail in it, then use that as the content value set for the restSetResponse() call.

这有点像杰瑞构建的，但是在这种情况下，我认为您受ColdFusion杰瑞构建的约束。

This is a bit jerry-built, but you're constrainted by the jerry-built-ness of ColdFusion in this instance, I think.

我've 记录了与此相关的错误。
