问题
I am trying to send POST request with custom headers using flash, but I can only get it to send the request as GET even when I use request.method = URLRequestMethod.POST;
Here is my code:
package {
import flash.display.Sprite;
import flash.events.*;
import flash.net.*;
public class URLRequestExample extends Sprite {
private var loader:URLLoader;
public function URLRequestExample() {
loader = new URLLoader();
configureListeners(loader);
var url:String = "http://example.com/";
var headers:Array = [
new URLRequestHeader("X-CUSTOM-HEADER", "X-VALUE"),
new URLRequestHeader("Accept", "application/json")
];
var requestVars:URLVariables = new URLVariables();
requestVars.test = "test";
request.data = requestVars; // If this line and the one under it are commented the request goes as GET
request.requestHeaders = headers; // ^with no request headers
var request:URLRequest = new URLRequest();
request.method = URLRequestMethod.POST; // Using URLRequestMethod.POST but the request is still sent as GET
request.url = url;
try {
loader.load(request);
} catch (error:Error) {
trace("Unable to load requested document.");
}
}
private function configureListeners(dispatcher:IEventDispatcher):void {
dispatcher.addEventListener(Event.COMPLETE, completeHandler);
dispatcher.addEventListener(Event.OPEN, openHandler);
dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler);
dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
dispatcher.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
}
private function completeHandler(event:Event):void {
var loader:URLLoader = URLLoader(event.target);
trace("completeHandler: " + loader.data);
}
private function openHandler(event:Event):void {
trace("openHandler: " + event);
}
private function progressHandler(event:ProgressEvent):void {
trace("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal);
}
private function securityErrorHandler(event:SecurityErrorEvent):void {
trace("securityErrorHandler: " + event);
}
private function httpStatusHandler(event:HTTPStatusEvent):void {
trace("httpStatusHandler: " + event);
}
private function ioErrorHandler(event:IOErrorEvent):void {
trace("ioErrorHandler: " + event);
}
}
}
And in my crossdomain.xml file I have:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" secure="false"/>
<allow-http-request-headers-from domain="*" headers="*" secure="false"/>
</cross-domain-policy>
回答1:
It seems it handles request as GET if there's no valid POST data attached. As soon as I added at least one valid key:value pair to the URLVariables object my Chrome dev tool reported the request method as POST: http://wonderfl.net/c/Ia2z
