如何从oData响应中恢复错误消息[SAPUI5] [英] How to recover a error message from oData response [SAPUI5]

问题描述

我遇到了这个问题，我搜寻了很多解决方法，但目前找不到任何解决方案...

I had this issue and i searched a lot how to fix it, but i can't find any solution at the moment...

嗯，这个问题是下一条错误消息，我可以写该错误，但我需要该批次的特定条目。

well, the issue is the next error message, i can write the error but i need a specific entry of this batch.

错误，消息框和批处理响应。

消息框中显示的代码：

{

headers：{
Content-Type： application / xml; charset = utf-8，
Content-Length： 1333，
DataServiceVersion： 1.0
}，

}

我需要仅恢复消息标签，但我不知道如何......

i need to recover the message tag only, but i don't know how....

我正在使用的代码是Sapui5 Fiori Apps的本机错误处理：

the code what i'm using is the native error handling for Sapui5 Fiori Apps:

    constructor: function(oComponent) {
        this._oResourceBundle = oComponent.getModel("i18n").getResourceBundle();
        this._oComponent = oComponent;
        this._oModel = oComponent.getModel();
        this._bMessageOpen = false;
        this._sErrorText = this._oResourceBundle.getText("errorText");

        this._oModel.attachMetadataFailed(function(oEvent) {
            var oParams = oEvent.getParameters();
            this._showServiceError(oParams.response);
        }, this);

        this._oModel.attachRequestFailed(function(oEvent) {
            var oParams = oEvent.getParameters("message");
            // An entity that was not found in the service is also throwing a 404 error in oData.
            // We already cover this case with a notFound target so we skip it here.
            // A request that cannot be sent to the server is a technical error that we have to handle though
            if (oParams.response.statusCode !== "404" || (oParams.response.statusCode === 404 && oParams.response.responseText.indexOf(
                    "Cannot POST") === 0)) {
                this._showServiceError(oParams.response);
            }
        }, this);
    },

    /**
     * Shows a {@link sap.m.MessageBox} when a service call has failed.
     * Only the first error message will be display.
     * @param {string} sDetails a technical error to be displayed on request
     * @private
     */
    _showServiceError: function(sDetails) {
        if (this._bMessageOpen) {
            return;
        }
        this._bMessageOpen = true;
        MessageBox.error(
            this._sErrorText, {
                id: "serviceErrorMessageBox",
                details: sDetails, 
                styleClass: this._oComponent.getContentDensityClass(),
                actions: [MessageBox.Action.CLOSE],
                onClose: function() {
                    this._bMessageOpen = false;
                }.bind(this)
            }
        );
    }

如果有人知道如何恢复该价值，我将非常感激。

if someone knows how to recover that value, I'll be very greatful.

问候。

推荐答案

i解决了此问题，更改了此部分代码的

i fixed this issue, changing this part of the code

if (oParams.response.statusCode !== "404" || (oParams.response.statusCode === 404 && oParams.response.responseText.indexOf(
                "Cannot POST") === 0)) {
            this._showServiceError(oParams.response);
        }
    }, this);

到

if (oParams.response.statusCode !== "404" || (oParams.response.statusCode === 404 && oParams.response.responseText.indexOf(
                    "Cannot POST") === 0)) {
                this._showServiceError($(oParams.response.responseText).find("message").first().text());

            }
        }, this);
