当我回显json_encode（$ json）时会出现错误，但是我的输出在 file.json 中复制并且工作正常。
请帮忙。

问题可能与您获得的响应以及您要解析的内容有关。您正在考虑从响应的根开始使用Object，而实际上数据可能是一个数组。 我建议你使用列表作为回调中的类型。喜欢或许类似的东西
@GET("/persons.json")
void contacts(Callback<List<person>> cb);
编辑：刚看到some better explanation in the thread
希望有所帮助

感谢您的帮助 问题现在解决了。 json很好，但隐藏的角色就在那里 我把charset变成了utf8而没有bom，现在正在工作。
