打印台出的为:
这边我写了一个方法进行处理,这里举出一个典型的例子以获取CommodityUnit的row和获取InvoiceDate时间为例
public static String getHashMapByJson(String jsonResult) {
JSONObject jsonObject = new JSONObject(jsonResult);
//将json格式转化为指定的map集合
Map>>>map=(Map)jsonObject.toMap();
String words_result = map.get("words_result").toString();
String s = map.get("words_result").get("CommodityUnit").get(0).get("row").toString();
Map>map1=(Map)jsonObject.toMap();
//获取发票日期
String invTime = map1.get("words_result").get("InvoiceDate");
return invTime;
}
最后在测试段成功获取
测试端代码如下,
测试的时间调用方法调取方法
String invTime = BaiDuOCR.getHashMapByJson(jsonResult);
System.out.println(invTime);
打印内容如下:
测试CommodityUnit的row调用的方法
String s = BaiDuOCR.getHashMapByJson(jsonResult);
System.out.println(s);
运行成功
