Knockout.js 处理错误：尝试登录时HttpRequestMethodNotSupportedException

我正在尝试使用oracle jet登录页面，使用npm yoeman软件包管理器和grunt构建工具。 以下是从服务器引发的错误响应：

o、 s.s.o.provider.endpoint.TokenEndpoint:处理错误： HttpRequestMethodNotSupportedException，请求方法'GET'不支持 支持

但我使用Ajax方法作为POST

define(['ojs/ojcore','knockout', 'ojs/ojinputtext', 'ojs/ojbutton', 
'ojs/ojknockout-validation', 'ojs/ojmodel'
], function (oj, ko) {
/**
 * The view model for the main content view template
 */
function logintestContentViewModel() {
    var self = this;
    self.tracker = ko.observable();
    self.username = ko.observable("");
    self.password = ko.observable("");
    self.clickedButton = ko.observable();
    self.buttonClick = function(data, event)
    {
        //alert("call"+JSON.stringify(data));
        var trackerObj = ko.utils.unwrapObservable(self.tracker);


        alert("submittedValue====="+self.username());
        alert("password====="+self.password());
        //self.submittedValue();
        //change this to a valid ajax call.
        alert("ajax call initiated");


        self.url = "http://192.168.0.100:8080/oauth/token?grant_type=password";

        //this.url += "client_id=my-trusted-client&client_secret=clientpassword";
        $.ajax({

在本例中，您将POST作为“type”的值。尝试将“type”更改为“method”，看看是否有帮助

从jQuery.ajax API文档：

var menuId = $( "ul.nav" ).first().attr( "id" );
var request = $.ajax({
  url: "script.php",
  method: "POST",
  data: { id : menuId },
  dataType: "html"
});

request.done(function( msg ) {
  $( "#log" ).html( msg );
});

request.fail(function( jqXHR, textStatus ) {
  alert( "Request failed: " + textStatus );
});

console.log（textStatus）的输出是什么？请提供开发者工具控制台的日志错误显示请求方法“GET”不受支持，但在您的代码中，您的ajax代码类型为：“POST”

if you wanna post and get a response use this 

var dataVal2 = {your data};
 $.ajax({
type: "POST",
 url: "url",
 data: JSON.stringify(dataVal2),
contentType: "application/json; charset=utf-8", 
dataType: "json",
processData: true,
 success: function (data, status, jqXHR) { 
alert(data.result);
var projectId = data.result;
alert(projectId);
  },
 error: function (xhr) {  
alert(xhr.responseText);
 }

if you want a response by using GET method use this

var data = {your data};
                    $.getJSON("url", data).then(function (resData) {
                    self.DataResponse(resData); 
                    });
and your error function alike in post method
