decode Json string

toolater · 2015-02-04 01:13:21

I receive some Json data from webserver , but the contents were encoded into Utf8,
"title":"\u5317\u4eac\u706b\u8f66\u7ad9\u552e\u7968\u5458\u8d2a\u6c61140\u4f59\u4e07\u9000\u7968\u6b3e \u5224\u521110\u5e74",
can I decode it?

Thank you for help

Yes.

Thank you for reply, but the problem is I can not find the document how to decode by using mORMot .

The easiest is to use SynCommons.pas, then a TDocVariant:

var doc: variant;
begin
  doc := _JsonFast('{"title":"\u5317\u4eac\u706b\u8f66\u7ad9\u552e\u7968\u5458\u8d2a\u6c61140\u4f59\u4e07\u9000\u7968\u6b3e \u5224\u521110\u5e74"}');
  writeln(doc.title);
end;

Ensure you convert the JSON as expected into our RawUTF8 string, using e.g.

begin
  doc := _JsonFast(StringToUTF8(aStringContainingJson));
...

If you're just trying to work out what the data is, I think https://json-csv.com decodes UTF8, then you can at least view the data there.

I know what the data is, it is just some Asiatic Unicode characters.
When I run the above code, doc.title contains '北京火车站售票员贪污140余万退票款判刑10年'.
So conversion does just work.
