如何解决 alfresco sdk 中 alfresco webscripts 中的 CORS 错误? [英] How to resolve CORS error in alfresco webscripts in alfresco sdk?

问题描述

我创建了一个 alfresco webscript，可以使用这样的 url 访问:

I have created a alfresco webscript which can be accessed using thus url :

http://localhost:9191/alfresco/s/search/item/{itemIid}例如:http://localhost:9191/alfresco/s/search/item/it0001

http://localhost:9191/alfresco/s/search/item/{itemIid} e.g. : http://localhost:9191/alfresco/s/search/item/it0001

当我直接从浏览器地址栏点击它时，它工作得很好，但是当我从我的 angular 服务中调用它时，我收到了 CORS 错误

when i hit directly from the browser address bar it work perfectly but when i invoke this from my angular service then i am getting CORS error

无法加载 http://localhost:9191/alfresco/s/search/item/it0001:对预检请求的响应未通过访问控制检查:请求的资源上不存在Access-Control-Allow-Origin"标头.因此，不允许访问源 'http://localhost:4201'.

Failed to load http://localhost:9191/alfresco/s/search/item/it0001: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4201' is therefore not allowed access.

我的角度部分是这样的:

My angular part is this :

convert1(itemId:string){
    var headers = new Headers();
    headers.set('Content-Type','*');
    headers.set('Access-Control-Allow-Origin','*');
    headers.append('Authorization','Basic zfsdfsdfsdfdsf=');    
    return  this.http.get(http://localhost:9191/alfresco/s/search/item/it0001,{headers:headers});   
}

在 alfresco-repo 方面，我在 webscript 代码中添加了以下内容，但这没有帮助.

In alfresco-repo side I have addedd following in webscript code but this has not helped.

response.setHeader("Access-Control-Allow-Origin", "*"); 

我可以在我的 alfresco-repo amp 插件中做哪些改变来避免这个错误.

what changes i can do in my alfresco-repo amp plugin so that this error can be avoided.

任何见解将不胜感激.

1. 在 alfresco/WEB-INF/lib 中添加了 cors-filter-2.5.jar、java-property-utils-1.9.1.jar 或 cors-filter-2.4.jar 和 java-property-utils-1.9.1.jar 或 cors-filter-1.9.3.jar 但它对我不起作用.

推荐答案

尝试以下步骤:

1. 进入 WEB-INF 下扩展的 alfresco webapp 目录并编辑 web.xml.
2. 搜索CORS 过滤器".
3. 取消注释过滤器.
4. 现在重新启动 Tomcat 并重试.
