在 as3 AIR 中发出 HTTP POST 请求

Question

我正在尝试通过 as3 AIR for mobile 发出与此 curl 请求等效的 HTTP POST 请求：

curl -d '{"firstname": "John", "lastname": “Doe"}' -H 'Content-Type: application/json' http://eve-demo.herokuapp.com/people

这是我的代码：

var urlVariables:URLVariables = new URLVariables();
urlVariables.firstname = "Jhon";
urlVariables.lastname = "Doe";

var request:URLRequest = new URLRequest();
request.url = "http://eve-demo.herokuapp.com/people";
request.contentType = "multipart/form-data";
request.method = URLRequestMethod.POST;
request.data = urlVariables;

var contentTypeHeader:URLRequestHeader = new URLRequestHeader("Content-Type", "application/json");
var acceptHeader:URLRequestHeader = new URLRequestHeader("Accept", "application/json");
var formDataHeader:URLRequestHeader = new URLRequestHeader("Content-Type", "multipart/form-data");

request.requestHeaders = [acceptHeader, formDataHeader];

postLoader = new URLLoader();
postLoader.dataFormat = URLLoaderDataFormat.BINARY;
postLoader.addEventListener(Event.COMPLETE, loaderCompleteHandler);
postLoader.addEventListener(HTTPStatusEvent.HTTP_STATUS, httpStatusHandler);
postLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
postLoader.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);

try
{
    postLoader.load(request);
}
catch (error:Error)
{
    trace("Unable to load post URL");
}

但我收到以下错误：

[HTTPStatusHandler]: [HTTPStatusEvent type="httpStatus" bubbles=false cancelable=false eventPhase=2 status=400 redirected=false responseURL=null]
[IOErrorHandler]: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032: Stream Error. URL: http://eve-demo.herokuapp.com/people" errorID=2032]

任何人对如何使用“multiform/form-data”（无需上传任何文件）发出 http post 请求有任何建议吗？？

谢谢

URLVariables 旨在与 url 编码的变量一起使用，而不是 JSON。尝试将 data 设置为 JSON 字符串：

var params:Object = { firstname: "John", lastname: "Doe" };
request.data = JSON.stringify(params);
