Iterate over a large JSON Array with JSONPath

纵然是瞬间 提交于 2020-01-28 10:17:46
问题 I have a simple Java app that needs to traverse a large JSON array (with around 20K items), and within each array, I parse a sub-array. Each item looks like this: {"index":0,"f1":[2,16,16,16,16,16,32,16],"f2":[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0],"startTime":0.0} I am using JSONPath to iterate over each item. What I do is first I read the length, and simply iterate over

Parse only one field in a large JSON string

问题 I have a JSON string of the following format: { "foo": "small_vale" "baz": "large_value" "bar": "another_large_value" } How can I efficiently extract foo while ignoring the rest of the fields? Basically, I'm using Gson and I defined a "lean class" like that: MyClass { private String foo; } If I'm ensuring that foo appears first in the JSON string, would Gson still scan the whole string, or is it smart enough to stop? Should I use JsonPath instead? 回答1: To answer on this question we need to

1、需求背景 在实际的接口测试时,传参有时候可能需要很多,也可能我们就是想要一份完整的参数,必填项和非必填项都包含在内,好比如下的 json : { "store" : { "book" : [ { "category" : "reference" , "author" : "Nigel Rees" , "title" : "Sayings of the Century" , "price" : 8.95 } , { "category" : "fiction" , "author" : "Evelyn Waugh" , "title" : "Sword of Honour" , "price" : 12.99 } , { "category" : "fiction" , "author" : "Herman Melville" , "title" : "Moby Dick" , "isbn" : "0-553-21311-3" , "price" : 8.99 } , { "category" : "fiction" , "author" : "J.

FastJson 之 JSONPath的使用

转载自: https://springboot.io/t/topic/309 叙述 jsonpath,类似于xpath。都是通过一种字符串表达式,来快捷检索json里面的数据。在非常复杂的json结构中,对于一些获取和判断操作,不需要层层的去get。可以通过简洁的JsonPath表达式获取到结果。 解析 JSONPath 构造方法 public JSONPath(String path) public JSONPath(String path, SerializeConfig serializeConfig, ParserConfig parserConfig) 静态属性/方法 public static Object eval(Object rootObject, String path) public static Object extract(String json, String path, ParserConfig config, int features, Feature... optionFeatures) public static Object extract(String json, String path) * 根据path检索值 * extract,按需计算, 性能会更好 public static int size(Object rootObject,

性能测试-JMeter断言之JSON断言

人走茶凉 提交于 2020-01-07 17:58:29
前面一节我们学习了JMeter断言之响应断言,今天我们来学习JMeter另一种断言方法: JSON断言。 JSON用于描述文本数据结构,有如下形式: 1.对象(object) 对象是一组无序的名称/值对。对象以{(左大括号)开始,以}(右 大括号)结束。每个名称后面跟着:冒号, 名称/值对之间用逗号分隔。 比如: {"name":"zhangsan","sex":1,"age":25} 2.数组(Array) 数组是值的有序集合。数组以[(左中括号)开始,以](右中括号) 结束。值之间用逗号分隔。 比如: { "man":[{"name":"zhangsan","sex":1,"age":21}, {"name":"lisi","sex":0,"age":18}, {"name":"wangwu","sex":0,"age":25}] } 3.值(value) 值可以是字符串、数字、true/false、null、对象或数组。 4.字符串(string) 字符串是由零个或多个Unicode字符组成的序列,用双引号括起来, 使用反斜杠转义。 字符表示为单个字符串。字符串非常类似于C或Java中的字符串。 5.数字(number) 一系列0-9的数字组合,可以为负数或者小数。还可以用e或者E表示 为指数形式; 数字非常类似于C或Java数字,但只是不使用八进制和十六进制格式。 6
