我有一个带有 XSA 的 SAP HANA Express 服务器，我创建了一个带有 DB 和 NodeJS 模块的 MTA 应用程序，在 NodeJS 模块中我创建了一个连接到 DB 模块的 .xsodata。

XSO数据定义：

service {
    //Definición de servicios
    "SISGASTOS"."CATEGORIA" as "Categoria"
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_categoria");
    "SISGASTOS"."ESTADO" as "Estado"
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_estado");
    "SISGASTOS"."PROYECTO" as "Proyecto"
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_proyecto");
    "SISGASTOS"."TIPO_DOCUMENTO" as "TipoDoc"
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_tipo_documento");
    "SISGASTOS"."INFORME" as "Informe" 
        navigates ("Informe_Comentario" as "Comentarios", "Informe_Proyecto" as "Proyecto", "Informe_Estado" as "Estado","Informe_Gasto" as "Gastos", "Informe_Hist" as "Info_Historial")
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_informe");
    "SISGASTOS"."HIST_INFORME" as "Hist_Informe"
        navigates ("Hist_Informe_Estado" as "Estado")
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_hist_informe");
    "SISGASTOS"."COMENTARIO_INFORME" as "ComentarioInforme";
//      create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_comentario_informe");
    "SISGASTOS"."GASTO" as "Gasto" 
        navigates ("Gasto_Categoria" as "Categoria", "Gasto_TipoDoc" as "TipoDoc", "Gasto_Estado" as "Estado", "Gasto_Comentario" as "Comentarios", "Gasto_Anexo" as "Anexos", "Gasto_Hist" as "Gasto_Historial")  
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_gasto");
    "SISGASTOS"."HIST_GASTO" as "Hist_Gasto"
        navigates ("Hist_Gasto_Estado" as "Estado")
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_hist_gasto");
    "SISGASTOS"."COMENTARIO" as "Comentario"
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_comentario");
    "SISGASTOS"."ANEXO" as "Anexo"
        create events ( before "movilidad.rindegastos:Informe.xsjslib::crear_anexo");

    //Asociacion Historiales
    association "Hist_Gasto_Estado"
        principal "Hist_Gasto"("ID_ESTADO") multiplicity "1"
        dependent "Estado"("ID_ESTADO") multiplicity "1";
    association "Hist_Informe_Estado"
        principal "Hist_Informe"("ID_ESTADO") multiplicity "1"
        dependent "Estado"("ID_ESTADO") multiplicity "1";

    //Asociacion Informe    
    association "Informe_Comentario"
        principal "Informe"("ID_INFORME") multiplicity "1"
        dependent "ComentarioInforme"("ID_INFORME") multiplicity "*";
    association "Informe_Proyecto"

    association "Informe_Hist"
        principal "Informe"("ID_INFORME") multiplicity "1" 
        dependent "Hist_Informe"("ID_INFORME") multiplicity "*";

    //Asociación Gasto
    association "Gasto_Categoria" 
        principal "Gasto"("ID_CATEGORIA") multiplicity "1" 
        dependent "Categoria"("ID_CATEGORIA") multiplicity "1";
    association "Gasto_TipoDoc" 
        principal "Gasto"("ID_TIPO_DOCUMENTO") multiplicity "1" 
        dependent "TipoDoc"("ID_TIPO_DOCUMENTO") multiplicity "1";
    association "Gasto_Estado" 
        principal "Gasto"("ID_ESTADO") multiplicity "1" 
        dependent "Estado"("ID_ESTADO") multiplicity "1";   
    association "Gasto_Comentario" 
        principal "Gasto"("ID_GASTO") multiplicity "1" 
        dependent "Comentario"("ID_GASTO") multiplicity "*"; 
    association "Gasto_Anexo" 
        principal "Gasto"("ID_GASTO") multiplicity "1" 
        dependent "Anexo"("ID_GASTO") multiplicity "*";
    association "Gasto_Hist"
        principal "Gasto"("ID_GASTO") multiplicity "1" 
        dependent "Hist_Gasto"("ID_GASTO") multiplicity "*";
}

我们使用更新操作从 SAPUI5 应用程序调用服务。

        submitChanges: function() {
        this.getView().getModel("oModelDialogo").setProperty("/busy", true);
        this.getView().getModel().submitChanges({
            success: function(oResult) {
                this.getView().getModel("oModelDialogo").setProperty("/busy", false);
                console.log(oResult);
            }.bind(this),
            error: function(oError) {
                this.getView().getModel("oModelDialogo").setProperty("/busy", false);
                console.log(oError);
            }.bind(this)
        });
    },

但响应未实现 501：

--batch_1523471867867_0
Content-Type: application/http
Content-Transfer-Encoding: binary

HTTP/1.1 501 Not Implemented
Content-Type: application/json;charset=utf-8

{"error":{"code":501,"message":{"lang":"en-US","value":"Not implemented"}}}

读取、创建和删除操作正常，只有更新操作有问题。

编辑：

作为 0x17 建议，我将清单文件中的 defaultUpdateMethod 更改如下：

    "models": {
        "i18n": {
            "type": "sap.ui.model.resource.ResourceModel",
            "settings": {
                "bundleName": "Adjuntos.i18n.i18n"
            }
        },
        "": {
            "dataSource": "mainService",
            "preload": true,
            "settings": {
                "defaultBindingMode": "TwoWay",
                "defaultUpdateMethod": "sap.ui.model.odata.UpdateMethod.Put"
            }
        }
    },

这样更新请求就起作用了！谢谢。

你能请。检查更新操作期间发送的完整请求标头？我想如果请求方法设置为 MERGE 可能会发生这种情况

我假设您在应用程序中使用 OData V2 模型。但是，在（基于 Cloudfoundry 之外的）OData V2 API 的 HANA 版本中，默认情况下不支持 MERGE。

您可以将 defaultUpdateMethod 设置为 PUT（在 manifest.json 中）然后再试一次吗？您也可以像这样在控制器代码中进行更改

在此处输入图像描述

SCP Neo 与 SAP XSA（基于 cloudfoundry）中的 OData v2 API 存在细微差别。后者在 V2 API 方面不如前者强大，但它正在慢慢倾向于使用 OData V4 API（这很好）
