I am getting the error in JsonObject: org.json.JSONException: Value Authorization of type java.lang.String cannot be converted to JSONObject In my android application, I just pass the API key and URL id to get the JSON response in the following URL. I display the JSON content using JSON array. But if I: public class AndroidAPiActivity extends Activity { /* * FlickrQuery = FlickrQuery_url * + FlickrQuery_per_page * + FlickrQuery_nojsoncallback *

How to add that object to my array with java? 回答1: As others have suggested, you can simply use the add method in the JsonArray builder. import javax.json.*; public class JsonExample { public static void main(String[] args) { JsonObject personObject = Json.createObjectBuilder() .add("name", Json.createObjectBuilder() .add("given", "John") .add("middle", "Edward") .add("surname"

第一种是formdata形式，在header参数里可以直接看到 代码demo如下： url=‘http://posturl‘;JSONObject postData = new JSONObject(); postData.put("shopid", 1); JSONObject json = restTemplate.postForEntity(url, postData, JSONObject. class ).getBody(); 使用RestTemplate发送multipart/form-data格式的数据 String url = ‘http://posturl‘; MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>(); map.add("shopid","1"); HttpHeaders headers = new HttpHeaders(); headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED); HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map,

json有两种数据结构，分别是有序的jsonArray和无序的jsonObject。 使用gson解析gson数据首先要导入gson的jar包 jsonArray 文件： { } jsonObject文件： { } java代码： package testJson; import java.io.FileNotFoundException; import java.io.FileReader; import com.google.gson.JsonArray; import com.google.gson.JsonIOException; import com.google.gson.JsonObject; import com.google.gson.JsonParser; import com.google.gson.JsonSyntaxException; public class TestJson { public static void main(String[] args) { try { //解析jsonArray数据 // JsonParser parser=new JsonParser(); //创建JSON解析器 // JsonObject object; //创建JsonObject对象 // object = (JsonObject) parser

JSONObject对同一个key重新put时，新值就会取代旧值，没有set之类的方法 构建json string时，所有的引号都要转义 package xx; import com.alibaba.fastjson.JSON; import com.alibaba.fastjson.JSONObject; // 对JSONObject中的指定字段重新赋值 public class testJsonReplace { public static void main(String[] args) { String query_jsonstr = "{\"timezone\":\"GMT+0\",\"action\":\"front_BRAND\",\"format\":\"true\",\"lan\":\"en_us\",\"column\":[\"day\",\"impressions\",\"clicks\",\"ctr\",\"brand_estimated_ecpm\",\"pay_out\"],\"dimension\":[\"day\"],\"filter\":{\"posid\":{\"op\":\"in\",\"value\":\"2454105\"}},\"start\":1528761600000,\"end\":1529452800000}";

首先导入核心包fastJson和commons-io包 <!-- fastJson --> <dependency> <groupId> com.alibaba </groupId> <artifactId> fastjson </artifactId> <version> 1.2.47 </version> </dependency> <!-- https://mvnrepository.com/artifact/commons-io/commons-io --> <dependency> <groupId> commons-io </groupId> <artifactId> commons-io </artifactId> <version> 2.4 </version> </dependency> 我的json数据是放在resources下 核心代码 package com.shengxun.service.impl ; import com.alibaba.fastjson.JSONArray ; import com.alibaba.fastjson.JSONObject ; import com.shengxun.domian.CmpNo ; import org.apache.commons.io.FileUtils ; import org

采用的jar包信息： <groupId>org.json</groupId> <artifactId>json</artifactId> <version>20160810</version> JSONObject json对象，使用大括号{}(如:{key:value}),其实就是一个键值对 JSONArray json数组，采用中括号[],数组元素就是json对象。 示例： [{key1:{key2-0:'value1-0',key2-1:'value1-1'}},{}] 这个字符串就是一个JSONArray格式,可以在创建JSONArray对象的时候将String字符串传递到构造函数中，如下代码: import org.json.JSONArray; /** { } 输出： {"key2-1":"value1-1","key2-0":"value1-0"} 再看插入数据的例子： import org.json.JSONArray; /** { } 输出： [{"key1":{"key2-1":"value1-1","key2-0":"value1-0"},"zhu":"huiming"},{},"zzzz"] 文章来源: 熟悉JSONObject和JSONArray
