电话间隙船员,
我在使用 android 访问 web 服务时遇到问题。我使用iOS访问它没有问题。随附的代码使用公共网络服务,因此如果您愿意,可以尝试该代码。
在 iOS 上,我们得到一个 xmlhttp.status == 200 并返回数据。在 Android 上,我们得到一个 xmlhttp.status == 0。
我们正在使用cordova-1.8.1.jar
我们在 res/xml/cordova.xml 中设置了白名单,如下所示:
<access origin=".*"/>
我提出这个问题是因为我怀疑我们的白名单不起作用。
这是代码:
function testweather(){
var xhr= new XMLHttpRequest();
xhr.onreadystatechange = function(){
alert(xhr.readyState);
if(xhr.readyState == 4){
if(xhr.status == 200){
$( "#result" ).append( xhr.responseText );
}
else{
alert("can't get response. a.status:"+xhr.status);
}
}
}
var url = "http://graphical.weather.gov/xml/SOAP_server/ndfdXMLserver.php";
xhr.open("POST", url,true);
xhr.setRequestHeader("SOAPAction", "http://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl#NDFDgenByDayLatLonList");
xhr.setRequestHeader("Content-Type", "text/xml;charset=UTF-8");
xhr.setRequestHeader("Content-Length", 1536);
xhr.setRequestHeader("Access-Control-Allow-Origin", "*");
xhr.setRequestHeader("Accept", "application/soap+xml, application/dime, multipart/related, text/*");
xhr.setRequestHeader("User-Agent", "IBM Web Services Explorer");
xhr.setRequestHeader("Cache-Control", "no-cache");
xhr.setRequestHeader("Pragma", "no-cache");
xhr.setRequestHeader("Connection", "close");
var soapEnv = '' +
'<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ndf="http://graphical.weather.gov/xml/DWMLgen/wsdl/ndfdXML.wsdl">' +

xhr.send( soapEnv );
