Anyone know the number to 911 ? " Most Popular By Peter Wade Mar 4, 2017 The Deadpool 2 teaser trailer that has been playing exclusively in theaters before Logan was officially released by Ryan Reynolds on Saturday. As expected, Deadpool is still a second-rate hero and a fan of butt jokes, struggling to even get his super hero suit on Superman-style in a phone booth while a senior citizen is being mugged nearby.

问题：
我正在尝试从这个 JSON 中提取一些字段。但是有些字段是高度嵌套的，有些是单嵌套的。
例如，使用“帖子”字段，我可以获得标题、作者、语言键的值。但是，当我尝试获取国家、位置、人员、组织、情绪的值时，使用以下代码，我得到所有这些值。我的代码sn-p如下。
JsonArray postArray = result.getAsJsonObject().getAsJsonArray("posts");
System.out.println(postArray);
for(JsonElement o : postArray) {
System.out.println(o.getAsJsonObject().get("title"));
System.out.println(o.getAsJsonObject().get("author"));
System.out.println(o.getAsJsonObject().get("language"));
System.out.println(o.getAsJsonObject().get("country"));
System.out.println(o.getAsJsonObject().get("locations"));
System.out.println(o.getAsJsonObject().get("persons"));
System.out.println(o.getAsJsonObject().get("organizations"));
System.out.println(o.getAsJsonObject().get("sentiment"));
System.out.println ("--------------------------------------");
}
如何打印与所有字段/键对应的值？
【问题讨论】：
-
你的 json 在哪里？
-
而不是多次调用
o.getAsJsonObject()，只需在循环开始时调用一次，并将其存储在一个变量中 -
你的 json 格式错误
-
对 Json 无能为力。这是我从其他来源得到的。
