刚开始制作程序将数据上传到智能表中。问题是我收到错误＆＃34;无效的Accept标头。媒体类型不受支持。 ＆＃34;它发生在这里
connection = (HttpURLConnection) new URL(GET_SHEETS_URL).openConnection();
connection.addRequestProperty("Authorization", "Bearer " + accessToken);
这是我从smartsheet github

答案 0 :(得分：1)
错误消息Invalid Accept header是您的线索。您需要设置相应的Accept标头，在本例中为application/json。
在您设置connection变量的行下方添加以下行。
connection.setRequestProperty("Accept", "application/json");
此外，您可能有兴趣使用可用于Smartsheet的现有SDK，listed here。
