ActionScripts 3带内容标头的JSON

Question

我正在尝试将JSON发布到服务器，但代码不起作用。我找到了一些用ActionScript 3发布JSON的示例，但我需要在代码中定义内容类型。我在这里发布我的测试代码。

我在Firefox Restclient中测试了URL 标头 身体，它们可以工作。[！[输入图像描述在这里] [1]] [1]我敢肯定URL是真实的，并且在其他地方工作，但是在这里我有错误"打开URL"

url：" https：//api.thinger.io/v2/users/xperydey"

内容标头："应用程序/json"

身体：{" in"：true}

import flash.display.Sprite;
import flash.events.*;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.net.URLRequestHeader;
import flash.net.URLRequestMethod;
import flash.net.URLVariables;

var loader: URLLoader;
function ATN() {
    loader = new URLLoader();
    configureListeners(loader);
    var header: URLRequestHeader = new URLRequestHeader("Accept", "application/json");
    var request: URLRequest = new URLRequest("https://api.thinger.io/v2/users/***");
    request.data = new URLVariables("in:true");
    request.method = URLRequestMethod.POST;
    request.requestHeaders.push(header);
    try {
        loader.load(request);
    } catch (error: Error) {
        trace("Unable to load requested document.");
    }
}
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);
}
function completeHandler(event: Event): void {
    var loader: URLLoader = URLLoader(event.target);
    trace("completeHandler: " + loader.data);
}
function openHandler(event: Event): void {
    trace("openHandler: " + event);
}
function progressHandler(event: ProgressEvent): void {
    trace("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal);
}
function securityErrorHandler(event: SecurityErrorEvent): void {
    trace("securityErrorHandler: " + event);
}
function httpStatusHandler(event: HTTPStatusEvent): void {
    trace("httpStatusHandler: " + event);
}
function ioErrorHandler(event: IOErrorEvent): void {
    trace("ioErrorHandler: " + event);
}
ATN();

错误：

错误：错误＃2101：将字符串传递给urlvariables.decode（）必须为 一个URL编码的查询字符串，包含名称/值对。

在错误$/throwerror（）

flash.net:: urlvariables/decode（）

flash.net:: urlvariables（）

编辑：

function ATN() {
    loader = new URLLoader();
    configureListeners(loader);
    var header: URLRequestHeader = new URLRequestHeader("Accept", "application/json");
    var request: URLRequest = new URLRequest("https://api.thinger.io/v2/users/***");
    request.data = new URLVariables();
    var postData: Object = {"in": true};
    request.data = JSON.stringify(postData);
    request.method = URLRequestMethod.POST;
    request.requestHeaders.push(header);
    try {
        loader.load(request);
    } catch (error: Error) {
        trace("Unable to load requested document.");
    }
}

输出：

openHandler：[event type =" open" bubbles = false casutable = false EventPhase = 2] ProgressHandler加载：44总计：44

错误打开URL'https://api.thinger.io/v2/users/phydeyby'

httpstatushandler：[httpstatusevent type =" httpstatus" bubbles = false 取消= false eventphase = 2状态= 400重定向= false responseurl = null]

ioErrorhandler：[ioerrorevent type =" ioError" bubbles = false 取消= false eventphase = 2 text ="错误＃2032：流错误。url：url： https://api.thinger.io/v2/users/phydeyby"]

错误在于解析您提供给urlvariobles构造函数的字符串。urlvariables实际上仅用于构建名称/值对。如果要发送JSON，请直接设置数据属性：

var postData:Object = { "in": true };
request.data = JSON.stringify( postData );
