Saya cuba mengesahkan IBAN dalam wizard dalam SAPUI5. Saya menggunakan V2 ODataModel (sap.ui.model.odata.v2.ODataModel) 上使用 functionImport untuk ini.

Permintaan mengembalikan kod status 202 tetapi sebenarnya gagal. Berikut ialah respons (dari tab Rangkaian Firefox):

(buang semua kandungan sulit) Ini adalah hasil dalam konsol penyemak imbas:

Jadi ia perlu didaftarkan di suatu tempat. Kod saya untuk mendaftar panggilan balik adalah seperti berikut:

this.SERVICE.functionImport("CheckIBAN", XXX.Constants.HTTP_POST, XXX, true, {
            fnSuccess: jQuery.proxy(function (oData) {
                fnCallback(oData);
            }, this),
            fnError: fnError
        });

Sila ambil perhatian bahawa fungsi functionImport hanyalah pembalut di sekeliling sap.ui.model.odata.v2.ODataModel.callFunction dan melakukan operasi yang sama.

Tidak kira apa yang saya masukkan (input betul atau salah), ia sentiasa memanggil fnSuccess.

Bila dah guna ODataModel 的 read 函数（所以只是一个简单的 GET-request）时，一切正常，并且在发生错误时触发 fnError .
