通过JSON处理网络信息

build.gradle中引用如下

dependencies{
	implementation 'net.sf.json-lib:json-lib:2.2.3:jdk15'
    //json object
    implementation 'commons-beanutils:commons-beanutils:1.9.3'
    implementation 'commons-collections:commons-collections:3.2.1'
    implementation 'commons-lang:commons-lang:2.6'
    implementation 'net.sf.ezmorph:ezmorph:1.0.6'
}

通过Map的键值映射保存信息

private Map<String, Object> getTodayWeather(String datas) {
    //datas为从Web端获取的String
    Map<String, Object> map = new HashMap<String, Object>();
    JSONObject jsonData = JSONObject.fromObject(datas);
    //将String转换为jsonData
    JSONObject info = jsonData.getJSONObject("data");
    //获取名为data的数据块
    JSONObject ObserveInfo = info.getJSONObject("observe");
    //获取data数据块内部的observe数据块
    map.put("Degree", ObserveInfo.getString("degree").toString());
    //获取键值为degree的数据,并保存在Map中(键值为"Degree")
    return map;
}

通过Map获取信息

 String text = responseText;
 Map<String,Object> map = getTodayWeather(text);
//处理获取的信息
 String DegreeText=(map2.get("Degree") + "℃" );
//通过Map得到数据
