好吧,以前我问... SOAP原型AJAX SOAPAction头问题(不能超链接是不幸的是,“2”的链接没有足够的代表......见下文)JavaScript的SOAP XMLHttpRequest的问题移动
从来没有制定出。我认为它与Prototype有关,它会返回0作为onSuccess。我无法弄清楚内容类型的utf-8格式。现在,如果我回去直javascript和使用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>
这从未调用的onreadystatechange。如果取消注释 返回request.responseXML.childNodes [0] .childNodes [1] .childNodes [3] .childNodes [5] .textContent;
它会检索所需的值,如果你在Firebug中,你会看到readyState == 4和状态== 200(不是我检查的)。我通常不需要用勺子喂食,但我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。另外,并不是说这个问题确实很重要,但我正在批准Firefox上的请求是跨域的,但它确实适用于移动设备,因此呼叫不需要跨域确认,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!
人!非常感谢。绞尽脑汁!我现在可以继续我的生活! – 2010-02-26 04:03:02
