使用 Jsoup 获取网站查询数据时，一直提示 Content-Type 失败，详细错误信息如下所示：
1 org.jsoup.UnsupportedMimeTypeException: Unhandled content type. Must be text/*, application/xml, or application/xhtml+xml 2 .

查看 Content-Type 设置如下所示：
Jsoup.connect(url).header("Content-Type", "application/javascript; charset=utf-8")
更换设置信息，错误依然存在；重查 Jsoup 的文档时，发现有个忽略 ContentType 的设置，更改后如下所示：
Jsoup.connect(url).ignoreContentType(true)
再次，请求地址后，错误信息消失，即可成功获取相应的数据信息。
