You don't have to call .parseJSON(). Your response has already been parsed. You're getting that error because the object you pass to jQuery.parseJSON() is being converted to the string "[object Object]". The unexpected token is that "o" in "object".

您不必调用. parsejson()。你的反应已经被解析了。您将得到这个错误，因为您传递给jQuery.parseJSON()的对象被转换为字符串“[object object]”。意想不到的标记是“对象”中的“o”。
