Question

我的DSS服务有问题，因为我找不到任何问题的答案而感到沮丧。我的服务有一个sqlserver数据源，映射配置我的输出为JSON，并在使用内容类型application / json测试服务时，我收到一个错误。以下是dss碳原木。我以前遇到过这个问题，解决办法就是启用Escape Non Printable Characters，但即使我启用了它，我仍然会收到以下错误。请帮忙。

它也发生在我身上，解决方案是检查我是否添加了＆＃34;输出映射＆＃34;是一个正确的JSON。

复制粘贴你的＆＃34;输出映射＆＃34; http://www.jsoneditoronline.org/处的JSON，看看格式是否正确

结果中配置了JSON输出的DSS错误
