我的页面已经工作了一段时间,突然之间它给了我这个跨域请求错误。奇怪的是我正在对文件发出相对请求,所以我不明白为什么会得到这个。

错误:

选项https://www.aliahealthcare.com/php/central.php?logout=true 来源https://aliahealthcare.com不受 Access-Control-Allow-Origin 的允许。

发送 jquery-1.7.2.min.js:4 f.extend.ajax jquery-1.7.2.min.js:4 logout aliahealthcare.com/:841 选择器 aliahealthcare.com/:901 (匿名函数) aliahealthcare.com/ :713 f.event.dispatch jquery-1.7.2.min.js:3 h.handle.i jquery-1.7.2.min.js:3

XMLHttpRequest 无法加载https://www.aliahealthcare.com/php/central.php?logout=true

Access-Control-Allow-Origin 不允许来源https://aliahealthcare.com 。aliahealthcare.com/:1

代码:

 function logout (){

      $.ajax({
           type: "GET",
           url: "/php/central.php",
                   data: { logout: 'true' },
                   success: function(msg) {
                     if(msg=='1'){ 

                     location.reload();

                    } 
                    else if(msg=='0') {
                        alert("Logout Failed! Please try again!") 
                    }
                  },
                  error:function(msg){
                    alert("Error"+msg);
                    }

         });
     }

输出ajax结果时的结果:

Object {readyState: 1, setRequestHeader: function, getAllResponseHeaders: function, getResponseHeader: function, overrideMimeType: function…} abort: function (a){a=a||"abort",p&&p.abort(a),w(0,a);return this} always: function (){i.done.apply(i,arguments).fail.apply(i,arguments);return this} complete: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this} done: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this} error: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this} fail: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this} getAllResponseHeaders: function (){return s===2?n:null} getResponseHeader: function (a){var c;if(s===2){if(!o){o={};while(c=bG.exec(n))o[c[1].toLowerCase()]=c[2]}c=o[a.toLowerCase()]}return c===b?null:c} isRejected: function (){return!!i} isResolved: function (){return!!i} overrideMimeType: function (a){s||(d.mimeType=a);return this} pipe: function (a,b,c){return f.Deferred(function(d){f.each({done:[a,"resolve"],fail:[b,"reject"],progress:[c,"notify"]},function(a,b){var c=b[0],e=b[1],g;f.isFunction(c)?i[a](function(){g=c.apply(this,arguments),g&&f.isFunction(g.promise)?g.promise().then(d.resolve,d.reject,d.notify):d[e+"With"](this===i?d:this,[g])}):i[a](d[e])})}).promise()} progress: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this} promise: function (a){if(a==null)a=h;else for(var b in h)a[b]=h[b];return a} readyState: 0 responseText: "" setRequestHeader: function (a,b){if(!s){var c=a.toLowerCase();a=m[c]=m[c]||a,l[a]=b}return this} state: function (){return e} status: 0 statusCode: function (a){if(a){var b;if(s<2)for(b in a)j[b]=[j[b],a[b]];else b=a[v.status],v.then(b,b)}return this} statusText: "error" success: function (){if(c){var a=c.length;n(arguments),j?l=c.length:e&&e!==!0&&(k=a,o(e[0],e[1]))}return this} then: function (a,b,c){i.done(a).fail(b).progress(c);return this} __proto__: Object

URL 之间的区别是“www.”,我认为这足以触发“跨域”。您说得对,相对请求导致不同的 URL 很奇怪;也许这与 JQuery 的 ajax 方法有关。您可以通过手动输入完整的主机名或使用window.location
