BCB的TJSONObject是不是太弱了点?

Jonix 2011-05-12 10:27:53
我故意在 Value 中加了一个双引号,生成的Json文居然没有进行自动转换,
造成的问题就是解析失败。

好弱的东东啊,大家用的时候,要小心啊。

哪位有第三方的 JSON 读写类可用吗?

这是我常用的,国外开源的c写的json代码,我用效率还算可以,大数据量没有测试过。

自己写了一个JSON类,性能竟然高出TJSONObject约20%。

C++Builder自带的JSON类确实太弱了,不建议使用。

我翻了它的源码,然后加了以下代码后,就可以使用了。
但是比较活见鬼,在赋入值时需要这段代码,解析的时候,
这个类居然会自然转换了 !?


String SetJsonString(String Value)
{
TReplaceFlags Flags = TReplaceFlags() << rfReplaceAll;
Value = StringReplace(Value, "\\", "\\\\", Flags);
Value = StringReplace(Value, "\n", "\\n", Flags);
Value = StringReplace(Value, "\"", "\\\"", Flags);
Value = StringReplace(Value, "/", "\\/", Flags);
Value = StringReplace(Value, "\b", "\\b", Flags);
Value = StringReplace(Value, "\f", "\\f", Flags);
Value = StringReplace(Value, "\n", "\\n", Flags);
Value = StringReplace(Value, "\r", "\\r", Flags);
Value = StringReplace(Value, "\t", "\\t", Flags);

return Value;
}
