它的值是20个字典,每个字典的 Key 是推文的 ID,Value 是推文的详情。这个时候,我们再人工去修改一下代码,也能方便地提取一条推文的全部字段。 如何获取 JsonPathFinder 的源代码我已经放到 Github 上面了。地址为:GitHub - kingname/JsonPathFinder: A tools to find the path of a specific key in deep nes...

So, let’s find all values for a given key: public List<String> getValuesForGivenKey(String jsonArrayStr, String key) { JSONArray jsonArray = new JSONArray(jsonArrayStr); return IntStream.range(0, jsonArray.length()) .mapToObj(index -> ((JSONObject)jsonArray.get(index)).optString(...
// 定义JSON键值对的正则表达式Stringpattern="\"(\\w+)\":\"(.*?)\"";// 创建Pattern对象Patternr=Pattern.compile(pattern);// 创建Matcher对象Matcherm=r.matcher(json);// 匹配并提取JSON键值对while(m.find()){System.out.println("Key: "+m.group(1));System.out.println("Value: "+m....
Again, you should be aware that JSON_VALUE returns NVARCHAR, so unless you add CAST the index will be created on text. Interestingly, JSON parsing is faster than the deserialization of some special types, such as XML and spatial. You can find more information atbit.ly/2kthrrC. In summary...
