好吧,所以之前我问过... SOAP Prototype AJAX SOAPAction 标头问题(不幸的是,无法超链接,“2”链接的代表不足...见下文)
从来没有成功过。我认为它与原型有关,它将返回一个 0 作为 onSuccess。我无法弄清楚 Content-type utf-8 格式。现在,如果我回到直接的 javascript 并使用 xmlhttprequest
<html xmlns="http://www.w3.org/1999/xhtml">
function getUVIndex() {
// In Firefox, we must ask the user to grant the privileges we need to run.
// We need special privileges because we're talking to a web server other
// than the one that served the document that contains this script. UniversalXPConnect
// allows us to make an XMLHttpRequest to the server, and
// UniversalBrowserRead allows us to look at its response.
// In IE, the user must instead enable "Access data sources across domains"
// in the Tools->Internet Options->Security dialog.
if (typeof netscape != "undefined") {
netscape.security.PrivilegeManager.
enablePrivilege("UniversalXPConnect UniversalBrowserRead");
}
// Create an XMLHttpRequest to issue the SOAP request. This is a utility
// function defined in the last chapter.
var request = new XMLHttpRequest();
// We're going to be POSTing to this URL and want a synchronous response
request.open("POST", "http://iaspub.epa.gov/uvindexalert/services/UVIndexAlertPort?wsdl", false);
request.onreadystatechange=function() {
if (request.readyState==4) {
var index = request.responseXML.getElementByTagName('index')[0].firstChild.data;
alert(request.responseText);
}
}
// Set some headers: the body of this POST request is XML
request.setRequestHeader("Content-Type", "text/xml");
// This header is a required part of the SOAP protocol
request.setRequestHeader("SOAPAction", '""');
// Now send an XML-formatted SOAP request to the server
request.send(
'<?xml version="1.0" encoding="utf-8"?>' +
'<soap:Envelope' +
' xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"' +
' xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"' +
' xmlns:tns="urn:uvindexalert" xmlns:types="urn:uvindexalert/encodedTypes"' +
' xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"' +
' xmlns:xsd="http://www.w3.org/2001/XMLSchema">' +
' <soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">' +
' <tns:getUVIndexAlertByZipCode>' +
' <in0 xsi:type="xsd:string">12306</in0>' +
' </tns:getUVIndexAlertByZipCode>' +
' </soap:Body>' +
'</soap:Envelope>'
);
// If we got an HTTP error, throw an exception
if (request.status != 200) throw request.statusText;
//return request.responseXML.childNodes[0].childNodes[1].childNodes[3].childNodes[5].textContent;
}
getUVIndex();
</script>
这永远不会调用 onreadystatechange。如果取消注释返回 request.responseXML.childNodes[0].childNodes[1].childNodes[3].childNodes[5].textContent;
它将检索所需的值,如果您在 Firebug 中,您将看到 readyState == 4 和 status == 200(不是我检查的)。我通常不需要被勺子喂食,但我只是不明白为什么我没有从听众那里得到我需要的值,或者为什么它从来没有被调用过。此外,这并不重要,但我正在批准 Firefox 上的跨域请求,它确实适用于移动设备,因此呼叫不需要确认跨域,它会自动执行此操作。
我希望有人可以看看这个,看看我忽略了什么。谢谢!
