我已经为测试目的创建了一个简单的表,并希望为此在get_entity
中实现SEGW
方法。
我有一个RFC,它获取两个键并返回匹配的条目。
SELECT SINGLE * FROM ZORDER
INTO ORDERRETURN
WHERE ORDERADVENCO = ORDERADVENCOINPUT AND
POSITIONADVENCO = POSITIONADVENCOINPUT.
我试图用/sap/opu/odata/sap/ZORDER_RFC_SRV/OrderSet(Orderadvencoinput='10100', Positionadvencoinput='10')
调用它,但是我得到了错误400: Bad request
。
我的元数据返回以下内容:

lv_ORDERADVENCO = ls_key-value.
READ TABLE lt_keys with key name = 'Positionadvenco' into ls_key.
lv_POSITIONADVENCO = ls_key-value.
SELECT SINGLE * FROM ZORDER

WHERE ORDERADVENCO = lv_ORDERADVENCO and
POSITIONADVENCO = lv_POSITIONADVENCO.
IF sy-subrc = 0.
er_entity-ORDERADVENCO = ls_order-ORDERADVENCO.
ENDIF.
endmethod.

但在这种情况下,lv_ORDERADVENCO
和lv_POSITIONADVENCO
似乎没有任何价值。这使得sy-subrc = 4
失败了。
更新:所以我现在用:
/sap/opu/odata/SAP/ZORDER_RFC_SRV_01/OrderSet(Orderadvenco='10100',Positionadvenco='10')
..。但是得到错误:
<code>/IWBEP/CX_MGW_BUSI_EXCEPTION</code>
<message>Resource not found for segment 'Order'</message>
另外,我的Orderadvenco和Positionadvenco似乎没有捕捉到我试图传递的值。
PS:我也实施了
/sap/opu/odata/SAP/ZORDER_SRV/OrderSet
它工作得很好,但有趣的是它调用:
<id>http://vhcala4hci.wdf.sap.corp:50000/sap/opu/odata/SAP/ZORDER_SRV/OrderSet(Orderadvenco='10100',Positionadvenco='10')</id>
但是,当我试图调用该链接时,它会失败,出现与上面相同的错误。

好吧,问题是,尽管有电话:
OrderSet(Orderadvenco='10100',Positionadvenco='10')
lt_keys包含:
所以我不得不改变:
READ TABLE lt_keys with key name = 'Orderadvenco' into ls_key.
READ TABLE lt_keys with key name = 'Positionadvenco' into ls_key.
至:
READ TABLE lt_keys with key name = 'ORDERADVENCO' into ls_key.
READ TABLE lt_keys with key name = 'POSITIONADVENCO' into ls_key.
其他错误:
OrderSet(Orderadvenco='10100',Positionadvenco='10') --我不得不删除这个空格。
谢谢@mash

查看您的$metadata文件会发现错误。您的实体类型'Order‘有两个关键属性:'Orderadvencoinput’和'Positionadvencoinput‘。当试图访问/sap/opu/odata/sap/ZORDER_RFC_SRV/OrderSet(Orderadvencoinput='10100',时,Positionadvencoinput='10')表IT_KEY_TAB (或者在您的例子中是lt_keys)会填充这两个键。但是,您尝试从表lt_keys中读取的是填充为'Orderadvenco‘和'Positionadvenco’的名称字段的行。因此,这两个读取表总是失败的,因此ls_key仍然是初始的,因此lv_ORDERADVENCO和lv_POSITIONADVENCO是初始的。因此,SELECT将失败,subrc= 4。网关要做的一件常见事情是抛出400个HTTP,因为请求的资源OrderSet(Orderadvencoinput='10100',Positionadvencoinput='10')没有被填充(er_entity再次为首字母)。
您应该做的是将$metadata中的确切属性名称放入READ语句中。
