我的任务是为基于 ColdFusion 8 的 CMS 系统创建 API。在做了一些研究之后,我决定 RESTful API 是最好的选择,原因有以下三个:
- 它使用起来很简单
- 相当容易实施
- 优秀的长期解决方案
鉴于我首先是一名应用程序/系统程序员,高级 Web 开发不是我的专长,所以我没有重新发明轮子,而是开始为我们的 API 寻找一些框架。
我选择Taffy主要是因为我发现它的设计比 PowerNap 和 FW/1 更优雅,但是我在实现它时遇到了一些麻烦。
根据文档,我已将解压缩的“taffy”文件夹放在我们的 Web 根目录中,并在我们的开发站点内创建了一个 api 目录 -
xxx.xxx.xxx.xxx/dev.cms/api_mk3
里面是目录:
/resources/studentCollection.cfc
/resources/studentMember.cfc
/Application.cfc
/index.cfm
所有四个文件的内容如下:
学生收藏.cfc
<cfscript>
component extends="taffy.core.resource" taffy:uri="/students" {
public function get() {
//query the database for matches, making use of optional parameter "eyeColor" if provided
//then...
var someCollectionObject = ArrayNew(1);
someCollectionObject[1] = "Jason Bristol";
return representationOf(someCollectionObject).withStatus(200); //collection might be query, array, etc
}
}
</cfscript>
学生会员.cfc
<cfscript>
component extends="taffy.core.resource" taffy:uri="/students/{personName}" {
public function get(string personName) {
//find the requested person, by name
//then...
return noData().withStatus(404);//representationOf(personName).withStatus(200); //member might be a structure, ORM entity, etc
}
}
</cfscript>
应用程序.cfc
<cfcomponent extends="taffy.core.api">
<cfscript>
this.name = 'CMS-API';
variables.framework = {};
variables.framework.debugKey = "debug";
variables.framework.reloadKey = "reload";
variables.framework.reloadPassword = "true";
variables.framework.representationClass = "taffy.core.genericRepresentation";
variables.framework.returnExceptionsAsJson = true;
// do your onApplicationStart stuff here
function applicationStartEvent() {
}
// do your onRequestStart stuff here
function requestStartEvent() {
}
// this function is called after the request has been parsed and all request details are known
function onTaffyRequest(verb, cfc, requestArguments, mimeExt) {
// this would be a good place for you to check API key validity and other non-resource-specific validation
return true;
}
</cfscript>
索引.cfm
Blank, as per the documentation.
我遇到的问题是如果我要导航到
xxx.xxx.xxx.xxx/dev.cms/api_mk3/index.cfm/students
我会得到一个404

现在假设我正确理解了所有内容,我应该有一个 .json 格式的“Jason Bristol”响应或类似的内容。
我怀疑 IIS6 中的 MIME 类型或 URL 重写存在问题,但我不知道如何更正此问题的具体细节。很长一段时间以来,我一直在推动升级到 Windows Server 2008 RC2,但没有成功。
这是操作员错误还是可以修复?
编辑: 从我所见,我在 CF 日志中一无所获。以下是 IIS 日志中的条目:
