Senden einer Zertifikatanforderung und Installieren der Zertifikatantwort (Windows-Runtime-Apps mit JavaScript)
[ Dieser Artikel richtet sich an Windows 8.x- und Windows Phone 8.x-Entwickler, die Windows-Runtime-Apps schreiben. Wenn Sie für Windows 10 entwickeln, finden Sie weitere Informationen unter neueste Dokumentation]
Im folgenden Beispiel wird gezeigt, wie Sie eine Zertifikatanforderung an eine Zertifizierungsstelle senden, die Microsoft-Zertifikatdienste ausführt, und das ausgestellte Zertifikat installieren.
Hinweis Der myRequest-Wert ist eine Zeichenfolge, die von dem unter Erstellen einer Zertifikatanforderung beschriebenen Beispiel erstellt wird.
function submitCertificateRequest( myRequest ) {
var myMessage = "Submit certificate request to server ......";
// Use the XMLHttpRequest object to communicate with a helper service which bridges communication with Certificate Services.
var xmlHttpRequest = new XMLHttpRequest();
// State change event handler.
xmlHttpRequest.onreadystatechange = function() {
var xmlResult;
var certificate;
var errorObj;
var xmlElements;
// All of the data has been received.
if(xmlHttpRequest.readyState == 4) {
xmlResult = xmlHttpRequest.responseXML;
// Parse the xml message from the service to retrieve the certificate.
try {
xmlElements = xmlResult.getElementsByTagName("SubmitRequestResult");
if (1 != xmlElements.length) {
errorObj = new Error(0, "Server retunred more than 1 results");
throw errorObj;
}
else if (1 != xmlElements[0].childNodes.length) {
errorObj = new Error(0, "SubmitRequestResult element has more than 1 child nodes");
throw errorObj;
}
else if (3 != xmlElements[0].childNodes[0].nodeType) { //text node
errorObj = new Error(0, "SubmitRequestResult element's child node type " + xmlElements[0].childNodes[0].nodeType.toString() + " != 3");
throw errorObj;
}
else {
certificate = xmlElements[0].childNodes[0].nodeValue;
}
myMessage = myMessage + "\n\nReceived certificate from server, encoded certificate string =\n" + certificate;
sdkSample.displayStatus(myMessage);
}
catch (ex1) {
myMessage = myMessage + "\n\nCommunication with server failed. Error description = " + ex1.description;
// use a custom function (not shown) to display the error.
sdkSample.displayError(myMessage);
return;
}
// Call the installCertificate method to install the certificate in the app container.
try {
Windows.Security.Cryptography.Certificates.CertificateEnrollmentManager.installCertificate(certificate);
myMessage = myMessage + "\n\nCertificate installation succeeded. The certificate is in the app container certificate store";
sdkSample.displayStatus(myMessage);
}
catch (ex2) {
myMessage = myMessage + "\n\nCertificate installation failed.";
myMessage = myMessage + convertErrortoString(ex2);
sdkSample.displayError(myMessage);
}
}
}
var body = '<SubmitRequest xmlns="http://somename.org/"><strRequest>' + myRequest + '</strRequest></SubmitRequest>';
var url = "https://servername/CrossMachineEnrollmentService/SubmitRequest";
myRequest = "";
// Send the request.
xmlHttpRequest.open("POST", url, true);
xmlHttpRequest.setRequestHeader("Content-type", "text/xml");
xmlHttpRequest.send(body);
