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:

我们使用更新操作从 SAPUI5 应用程序调用该服务。
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)
});
},
但是响应是 Not Implemented 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、创建和删除操作工作正常，只有更新操作有问题。
编辑:
按照 0x17 的建议，我在 list 文件中更改了 defaultUpdateMethod，如下所示:
"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"
}
}
},
这样更新请求就可以工作了!谢谢。
最佳答案
你可以吗？检查更新操作期间发送的完整请求 header ？我想如果请求方法设置为 MERGE，可能会发生这种情况
我假设您正在 ui5 中使用 OData V2 模型应用程序。然而，在 HANA xsa版本(基于 Cloudfoundry)OData V2 API，默认情况下不支持 MERGE。
您可以将defaultUpdateMethod 设置为PUT(在manifest.json 中)并重试吗？您还可以在 Controller 代码中进行相同的更改，如下所示
The OData v2 APIs in SCP Neo vs SAP XSA (based on cloudfoundry) have subtle differences. The latter is not as robust as the former when it comes to V2 APIs but it is slowly tilting towards the use of OData V4 APIs (which is good)
