我正在尝试创建一个可编辑的SlickGrid(使用jquery-ui)并使用Dojo.

当我的页面包含
<script src="../../bower_components/dojo/dojo.js"></script>
<script src="../../bower_components/SlickGrid/lib/jquery-ui-1.11.3.js"></script>
<script src="../../mlads/fillDemo/FillDemo.js"></script>
控制台显示时

Error: multipleDefine
return mix(new Error(error), {src:"dojoLoader", info:info});  dojo.js (line 106)
src: dojoLoader   dojo.js (line 1896)
info: Object { pid="dijit",  mid="dijit/_WidgetsInTemplateMixin",  pack={...},  more...}

如果我注释掉jquery-ui行,那么错误就会消失.
FillDemo.js是我的源代码,它以

require(
[    "dojo/_base/declare",
     "dijit/_WidgetBase", 
     "dijit/_TemplatedMixin",
     "dijit/_WidgetsInTemplateMixin",
     "dijit/registry",
     "dijit/form/Button", 
     "dijit/form/DropDownButton",

我可以使用curl发布到我的Slack Incoming Webhook:

curl -X POST -H 'Content-type: application/json' --data '{"text":"Hello world"}' https://hooks.slack.com/services/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

但是当我使用时

$.ajax({
    url: "https://hooks.slack.com/services/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",
    data: '{"text": "Hello world"}',
    type: "POST",
    contentType: "application/json"
})
    .done(function (reply) {
        console.log("POST to Slack succeeded")
    })
    .fail(function (xhr, status, errorThrown) {
        console.log("Error in POST to Slack: " + errorThrown.toString())
    })

在我的应用程序的localhost:8090服务的页面中,我收到错误:

jquery.js:9536 OPTIONS https://hooks.slack.com/services/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 
400 (Bad Request)
XMLHttpRequest cannot load https://hooks.slack.com/services/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. 
Response for preflight has invalid HTTP status code 400

通常,我页面上的POST将转到我的服务器,该服务器为页面提供服务.所以我认为我的困惑与理解Webhooks如何工作有关.我认为同源政策禁止我发布到任意网址.但是为什么curl命令工作,我如何让我的页面做curl的工作呢？

我是否需要从服务器发送POST,而不是从客户端浏览器发送？
