使用 PATCH 方法更新 SAP BUSINESS ONE 服务层上的 salesOrderLines 时出现问题

Question

这是我收到的错误消息：

Access to XMLHttpRequest at 'http://192.168.0.4:50001/b1s/v1/Orders(334738)' from origin 'http://192.168.0.4:8000' has been blocked by CORS policy: Request header field b1s-replacecollectionsonpatch is not allowed by Access-Control-Allow-Headers in preflight response.

$.ajax({
        url: GlobalLink + "Orders("+DocEntry+")",  
        
        xhrFields: { withCredentials: true  },  
        headers:  { 'B1S-ReplaceCollectionsOnPatch' :true  } ,
     
         data: jdata,   
         type: "PATCH",    
          dataType : "json",     

Answer 1

您必须配置服务层以允许在 CORS 请求中使用此标头。可以通过网页界面“ServiceLayerController”来完成：

只需在此处添加标题“b1s-replacecollectionsonpatch”，用逗号分隔即可。
