},
result:4be26bc400d3c
}
访问这些数据最简单的方法是什么?我正在使用GSON模块。
解决方案
你去哪里
Type type = new TypeToken< Map< String,String>>(){}。getType();
映射< String,String> myMap = gson.fromJson({'k1':'apple','k2':'orange'},type);
I'm requesting data from a server which returns data in the JSON format. Casting a HashMap into JSON when making the request wasn't hard at all but the other way seems to be a little tricky. The JSON response looks like this:
{
"header" : {
"alerts" : [
{
"AlertID" : "2",
"TSExpires" : null,
"Target" : "1",
"Text" : "woot",
"Type" : "1"
},
{
"AlertID" : "3",
"TSExpires" : null,
"Target" : "1",
"Text" : "woot",
"Type" : "1"
}
],
"session" : "0bc8d0835f93ac3ebbf11560b2c5be9a"
},
"result" : "4be26bc400d3c"
}
What way would be easiest to access this data? I'm using the GSON module.
解决方案
Here you go
Type type = new TypeToken<Map<String, String>>(){}.getType();
Map<String, String> myMap = gson.fromJson("{'k1':'apple','k2':'orange'}", type);
