是否有用于JSON的流API? [英] Is there a streaming API for JSON?

问题描述

DOM是解析JSON的唯一方法吗?

Is DOM the only way to parse JSON?

推荐答案

某些JSON解析器确实提供了增量(流")解析器；对于Java，至少在json.org页的以下解析器中提供了这样的接口:

Some JSON parsers do offer incremental ("streaming") parser; for Java, at least following parsers from json.org page offer such an interface:

• 杰克逊(拉接口)
• Json简单(SAX风格的推送界面)

• Jackson (pull interface)
• Json-simple (SAX-style push interface)

(除了另一个答案所引用的Software Monkey的解析器之外)

(in addition to Software Monkey's parser referred to by another answer)

实际上，这么多JSON解析器不提供此简单的低级接口是很奇怪的-毕竟，它们已经需要实现低级解析，所以为什么不公开它.

Actually, it is kind of odd that so many JSON parsers do NOT offer this simple low-level interface -- after all, they already need to implement low-level parsing, so why not expose it.

编辑(2011年6月):Gson也有自己的流API (带有gson 1.6)

EDIT (June 2011): Gson too has its own streaming API (with gson 1.6)
