如何在7.02之前的ABAP中编码JSON [英] How to encode JSON in ABAP before 7.02

问题描述

正如霍斯特·凯勒(Horst Keller)在其 ABAP和JSON 帖子，"ABAP本地支持7.0.2和7.03/7.31版(内核补丁116)JSON".

As Horst Keller mentioned in his ABAP and JSON post, "with Releases 7.02 and 7.03/7.31 (Kernelpatch 116) JSON is supported natively in ABAP".

在我看来太通用的情况下，大概是7.02，因为下面的行:

Appartently 7.02 in my case of too generic because the line below:

writer = cl_sxml_string_writer=>create( type = if_sxml=>co_xt_json ).

返回错误:"The field CO_XT_JSON is unknown, but there is a field with the similar name CO_XT_XOP".

那么有什么方法可以轻松生成JSON?

关于类 CL_TREX_JSON_SERIALIZER :我在开发移动sap应用程序时也使用了该类，但发现创建的 JSON不是是有效的，因此我开始进行谷歌搜索，发现此 http://jsonlint.com/验证您的json是否有效.当然，您在调试时会遇到很多麻烦，原因是它确实起作用，而又没有弄清序列化程序已损坏.问候，zY

About the class CL_TREX_JSON_SERIALIZER: I also used this class during developping a mobile sap application and I found the created JSON not being valid, thus I started googling and found this http://scn.sap.com/community/mobile/blog/2012/09/24/serialize-abap-data-into-json-format (which also explains how to create a valid JSON serializer). Validate your json with json lint http://jsonlint.com/ to see if it is valid.. otherwise, thats for sure, you get a lot of trouble in debugging why it doenst work and dont get the point that the serializer is corrupt. regards, zY
