{
“appid_app”:“appid_app”,
“appid”:“appid”,
“appsecret_app”:“appsecret_app”,
“appsecret”:“appsecret”,
“partner_app”:“partner_app”,
“partner”:“partner”,
“partnerkey_app”:“partnerkey_app”,
“partnerkey”:“partnerkey”,
“redirect_uri”:“redirect_uri”,
“notifyurl”:“notifyurl”,
“website”:“website”
}

STR的字符串Json值如上
JSONObject jsonObject = JSONObject.fromObject(str);
String appid=jsonObject.getString(“appid”);
System.out.println(“appid:”+appid);

如果是数组就转换成字符串，或者.getJSONObject(0)
