344

它包括 344 和 0。

但如果我跟随

json 返回没问题 ( http://thawing-shelf-3867.herokuapp.com/Rockstars?format=json )

如何修复它。非常感谢你

Answer 1

json 不包含额外的数字 - 如果单击“查看 json 数据源”，您将看到预期的 json。所以，错误的不是 json 格式。

如果您查看响应（例如，使用 Chrome 开发工具的网络响应选项卡），您会看到额外的数字在 html 标记之外。在将 ServiceStack 响应传递给客户端之前，有些东西正在向它添加额外的字符。我会专注于您的配置设置。也许这与 Heroku 上的 nginx 中未正确设置字符编码有关？
