我需要将这些分隔的数据转换为JSON格式。请建议。

Answer 1

您可以通过一些拆分和替换操作来执行此操作。以下是Java中的内容示例，您可以将其转换为调用toJsonArr方法的json格式。

public static String toJsonArr(String src){
    StringBuilder builder = new StringBuilder();
    String objArray[] = src.split("\\|R\\|\\|L\\|");
    builder.append("[");
    for(String obj : objArray){
        builder.append(toJsonObj(obj)).append(",");
    }

    //remove last comma ,
    String str = builder.substring(0, builder.length()-1);

    return str+"]";
}

public static String toJsonObj(String src){
    StringBuilder builder = new StringBuilder();
    String elemArray[] = src.split("\\|L\\|");
    builder.append("{");
    for(String elem : elemArray){
                    //for empty lines
        if(elem.trim().length()!=0)
            builder.append(toJsonElem(elem)).append(",");
    }

    //remove last comma ,
    String str = builder.substring(0, builder.length()-1);

    return str+"}";
}

public static String toJsonElem(String src){
    StringBuilder builder = new StringBuilder();
    builder.append("\"").append(src.trim().replaceAll("\\|\\|", "\":\"")).append("\"");
    return builder.toString();
}
