HTTPRequest.request与sendData，似乎不能让这个工作 [英] HTTPRequest.request with sendData, can't seem to get this to work

问题描述

我试着用Dart包装我的头，在这样做时，向HTTPRequest中添加一些数据，结果很糟糕。我需要发送一个参数与这个请求，所以我想sendData变量可能会帮助我做到这一点。文档是稀疏的，最好的这种方法，所以我知道这只是我的语法错了。任何想法为什么这不工作？

I'm trying to wrap my head around Dart, and in doing so got stumped with adding some data to an HTTPRequest. I need to send a parameter with this request, so I figured the "sendData" variable would probably help me do that. Documentation is sparse at best for this method, so for all I know it's just my syntax that's wrong. Any idea why this wouldn't work?

HttpRequest.request(url, sendData:{"rnd":rnd.millisecondsSinceEpoch}).then(onLoadSuccess).catchError(onLoadError);

目前它在html_dartium.dart中储存，位于

Currently it tanks out in html_dartium.dart at

void send([data]) native "XMLHttpRequest_send_Callback";

只告诉我String expected。它不会说出字符串的位置，所以我被骗了。

And only tells me "String expected." It doesn't say where the string is expected, so I'm stumped. Any ideas/thoughts?

推荐答案

现在无法测试，但您可能需要对sendData进行JSON.encode。

Can't test right now, but you might want to JSON.encode the sendData.

'如果指定， sendData 将以[ByteBuffer]，[Blob] ，[String]或[FormData]沿着
与HttpRequest。 '

'If specified, sendData will send data in the form of a [ByteBuffer], [Blob], [Document], [String], or [FormData] along with the HttpRequest. '
