我有一个包含冒号分隔数据的文本文件。我如何将其转换为JSON对象？我在文件中有以下文字：

<Access-Control-Allow-Headers>

下面的代码是在java中。根据您的要求，您可能需要进行一些更改。

   import java.io.BufferedReader;
    import java.io.FileInputStream;
    import java.io.IOException;
    import java.io.InputStreamReader;

    public class Main {
        public static void main(String[] args) throws IOException {
            readFile();
        }

        public static void readFile() throws IOException {
            FileInputStream fileInputStream = null;
            try {
                fileInputStream = new FileInputStream("d:/input.txt");
                BufferedReader  br = new BufferedReader(new InputStreamReader(fileInputStream));
                String line = null;
                String obj = new String("[");
                while ((line = br.readLine()) != null) {
                    if (line.split(":").length > 1) {
                        Entry entry = new Entry(line.split(":")[0], line.split(":")[1]);
                        obj = obj +" \n "+ entry.toString();
                    }
                }
                obj = obj.replaceAll("\"BEGIN\":\"VCARD\"", "{");
                obj = obj.replaceAll("\"END\":\"VCARD\"", "},");
                obj = obj.substring(0, obj.lastIndexOf(","));
                obj = obj + "\n]";

                System.out.println(obj);
                br.close();
            } catch ( Exception e) {
                System.out.println(e);
            } finally {
                fileInputStream.close();
            }
        }
    }

    class Entry {
        private String key;
        private String value;
        Entry (String key, String value) {
            this.key = key;
            this.value = value;
        }

        @Override
        public String toString() {
            return "\""+ key + "\"" +  ":" +  "\"" +  value + "\"";
        }
    }

输出类似于json格式。
