如何在Java中将带有'hashtags'的字符串转换为json? [英] How do I convert a string with 'hashtags' to json in java?

问题描述

我在Java中有一个字符串，看起来可能像这样:

I have a String in java that might look like this:

String str = "Hello this is #David's first comment #excited"

我想将此字符串转换为json对象，但是当我使用以下代码时会引发错误:

I want to convert this string to a json object, but it throws an error when I use the below:

JSONObject json = new JSONObject(str);

我发现由于#"符号而引发错误.
还有没有其他麻烦将字符串转换为json的其他方法?

I have found out that it throws an error due to the '#' symbol.
Is there any other way to convert the string to json, without much hassle ?

推荐答案

问题不仅仅在于'#'符号；这是因为您尝试解析该字符串，就好像它已经是JSON.您可能想要这样的东西:

The problem is not so much the '#' symbols; it's that you are trying to parse the string as if it's already JSON. You probably want something like this:

JSONObject json = new JSONObject();
json.put("firstString", str);
String jsonString = json.toString();

或更简单地说(如果您想要的只是带引号的JSON字符串:

or, more briefly (if all you want is a quoted JSON string:

String jsonString = JSONObject.valueToString(str);
