我找到了一个
XMLHttpRequest的
reference
final req = new XMLHttpRequest();
req.open('GET','${Sections.home}/data/$name',false);
req.send();
_htmlBody = req.responseText;
但这是为了async = false,是否有一个async = true的工作示例？
在
https://code.google.com/p/dart/source/browse/branches/bleeding_edge/dart/samples/belay/bcap/bcap_client.dart有一个例子
原文链接：https://www.f2er.com/ajax/159999.htmlvoid privateInvoke(String ser,String method,String data,SuccessI ski,FailureI fki) {
if (urlRegex.hasMatch(ser)) {
var req = new XMLHttpRequest();
req.open(method,ser,true);
req.on.readyStateChange.add(void _(evt) {
if (req.readyState == 4) {
if (req.status == 200) {
ski(req.responseText);
} else {
fki(new BcapError(req.status,req.statusText));
}
}
});
req.send(data);
return;
} else {
super.privateInvoke(ser,method,data,ski,fki);
}
}
XMLHttpRequest request = new XMLHttpRequest();
request.on.readyStateChange.add((Event event) {
if (request.readyState == XMLHttpRequest.DONE && request.status == 200) {
callback("data:image/png;base64,${StringUtils.base64Encode(request.responseText)}");
}
});
...
request.open("POST",url,true,null,null);
request.setRequestHeader("Content-type","text/plain");
request.overrideMimeType("text/plain; charset=x-user-defined");
print("Chart request: ${data}");
request.send(data);
