我把Json转换NutMap出现错误

我在将字符串json转换成NutMap时报错,求解

@org.junit.Test
	public void test6(){
		String str = "content:{\"access_token\":\"3FL1_0oHp5mjBiy8O-rwfj-Yu4R6lVK_QyEb9c_RW4DFltHC3FqgYjFs74seHvDF_jkHM8lEAKOsbJdoqskRjP3740VSe54_itcc3GV4mI02N0lt7Dheln6aQ5gJSQWpZEUhAEAOTJ\",\"expires_in\":7200}";
		NutMap nm = (NutMap) Json.fromJson(str);
		System.out.println(nm);
	}

日志:

org.nutz.json.JsonException: !Json syntax error nearby [row:1,col:1 char 'c'], reason: 'Unexpect String = content:{"access_token":"3FL1_0oHp5mjBiy8O-rwfj-Yu4R6lVK_QyEb9c_RW4DFltHC3FqgYjFs74seHvDF_jkHM8lEAKOsbJdoqskRjP3740VSe54_itcc3GV4mI02N0lt7Dheln6aQ5gJSQWpZEUhAEAOTJ","expires_in":7200}'

贴错了贴错了.这是代码

@org.junit.Test
	public void test6(){
		String str = "{\"access_token\":\"3FL1_0oHp5mjBiy8O-rwfj-Yu4R6lVK_QyEb9c_RW4DFltHC3FqgYjFs74seHvDF_jkHM8lEAKOsbJdoqskRjP3740VSe54_itcc3GV4mI02N0lt7Dheln6aQ5gJSQWpZEUhAEAOTJ\",\"expires_in\":7200}";
		NutMap nm = (NutMap) Json.fromJson(str);
		System.out.println(nm);
	}

这是真实报错日志:
