问题描述
FW/1 似乎面向返回完整的网页，如果需要 JSON 数据怎么办?典型的布局如下所示:
FW/1 seems to be oriented to returning complete web pages what if JSON data is needed? A typical layout looks like:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>User Manager</title> <link rel="stylesheet" type="text/css" href="assets/css/styles.css" /> </head> <body> <h1>User Manager</h1> <ul class="nav horizontal clear"> <li><a href="index.cfm">Home</a></li> <li><a href="index.cfm?action=user.list" title="View the list of users">Users</a></li> <li><a href="index.cfm?action=user.form" title="Fill out form to add new user">Add User</a></li> <li><a href="index.cfm?reload=true" title="Resets framework cache">Reload</a></li> </ul> <br /> <div id="primary"> <cfoutput>#body#</cfoutput> </div> </div> </body> </html> 推荐答案我使用了覆盖Framework.cfc的onMissingView()方法的代码.
I have used code that overrides the onMissingView() method of Framework.cfc.
我将我的响应包装在一个名为 rc.json 的变量中，然后在我的 Application.cfc 中使用与此类似的代码.
I wrap my response up in a variable named rc.json then use code similar to this in my Application.cfc.
function onMissingView( rc ){ if( structKeyExists( rc, 'json' ){ var response = getPageContext().getresponse() response.setContentType( 'application/json' ); return serializeJSON( rc.json ); } else{ //we need this to fire off valid onMissignView error. raiseException( "FW1.viewNotFound", "Unable to find a view for '#request.action#' action.", " '#request.missingView#' does not exist."); } }当请求不是 AJAX 请求时，我使用其他逻辑来执行 rc.json 的 cfdump.但这已缩小到最低限度.
I use other logic to do a cfdump of rc.json when request is not an AJAX request. But this is scaled down to bare minimum.
