ABAP 随机时间戳解码问题 SOTR_MESS 032

场景：我们这边有个推企业API的接口，因为接口逻辑是必须按主体去推送。当按主体推送的时候就会涉及到批量的问题，为了方便记录传输记录，每次我都会生成一个新的token。

生成token的参数中涉及到一个timestamp，也就是时间戳。这个时间戳是JAVA的时间戳，在使用ABAP生成的时候我做了个转码：代码如下

    data time type tzntstmpl.
    data str1 type string.
    data str2 type string.
    data tstmp1 type p.
    data tstmp2 type p.
    data secs type tzntstmpl.

    TYPES:BEGIN OF TY_DATA,
            TSTMP1 LIKE TSTMP1,
            TSTMP2 LIKE TSTMP1,
            STR1 TYPE STRING,
            STR2 TYPE STRING,
            TIME_13 TYPE STRING,
            MESSAGE TYPE STRING,
          END OF TY_DATA.

    DATA:LS_DATA TYPE TY_DATA.
    DATA:LT_ZAFL_LOG TYPE TABLE OF ZAFL_LOG,
         LS_ZAFL_LOG LIKE LINE OF LT_ZAFL_LOG.

    TRY.
      GET TIME STAMP FIELD TIME.
    CATCH CX_ROOT INTO DATA(LS_ROOT) .
      LS_DATA-MESSAGE = LS_ROOT->GET_LONGTEXT( ).
    ENDTRY.



    tstmp1 = time.
    tstmp2 = '19700101000000'.

    try.
        secs = cl_abap_tstmp=>subtract(
          tstmp1 = tstmp1
          tstmp2 = tstmp2
        ).
      catch cx_parameter_invalid_range .

      catch cx_parameter_invalid_type .

    endtry.

    str1 = secs.
    str2 = time.
    TIME_13 = str1(10) && str2+15(3).

接着，诡异的事情出现了，如果调一次的时候基本没什么问题，但是当批量调的时候就会出现token生成失败的问题。后面做了日志发现

当 GET TIME STAMP FIELD TIME. 生成的TIME 以60结尾的时候，比如"20220812111160",通过cl_abap_tstmp=>subtract去获取时间戳就会有问题，报错是SOTR_MESS 032。

具体原因是在：TSTMP2SECS 的42行做时间戳解析的时候报异常了

解决办法：
在异常报错处wait一个非整秒，然后重新执行

    data time type tzntstmpl.
    data str1 type string.
    data str2 type string.
    data tstmp1 type p.
    data tstmp2 type p.
    data secs type tzntstmpl.

    TYPES:BEGIN OF TY_DATA,
            TSTMP1 LIKE TSTMP1,
            TSTMP2 LIKE TSTMP1,
            STR1 TYPE STRING,
            STR2 TYPE STRING,
            TIME_13 TYPE STRING,
            MESSAGE TYPE STRING,
          END OF TY_DATA.

    DATA:LS_DATA TYPE TY_DATA.
    DATA:LT_ZAFL_LOG TYPE TABLE OF ZAFL_LOG,
         LS_ZAFL_LOG LIKE LINE OF LT_ZAFL_LOG.

    TRY.
      GET TIME STAMP FIELD TIME.
    CATCH CX_ROOT INTO DATA(LS_ROOT) .
      LS_DATA-MESSAGE = LS_ROOT->GET_LONGTEXT( ).
    ENDTRY.



    tstmp1 = time.
    tstmp2 = '19700101000000'.

    try.
        secs = cl_abap_tstmp=>subtract(
          tstmp1 = tstmp1
          tstmp2 = tstmp2
        ).
      catch cx_parameter_invalid_range .
          WAIT UP TO '0.18' SECONDS.
          GET TIME STAMP FIELD TIME.
          tstmp1 = time.

          secs = cl_abap_tstmp=>subtract(
            tstmp1 = tstmp1
            tstmp2 = tstmp2
          ).

      catch cx_parameter_invalid_type .
          WAIT UP TO '0.18' SECONDS.
          GET TIME STAMP FIELD TIME.
          tstmp1 = time.

          secs = cl_abap_tstmp=>subtract(
            tstmp1 = tstmp1
            tstmp2 = tstmp2
          ).
    endtry.

    str1 = secs.
    str2 = time.
    TIME_13 = str1(10) && str2+15(3).
