我试图提出“registerSensor”请求。看到下面的xml文件。 但不幸的是，我只收到一个异常，关于一个NULL GET请求。 什么混淆我最深的是，我发送和POST方法读取的事实。从服务器请求（ogc）“Sensor Observation Service”（传感器观察服务）请求
我知道这个问题可能不适合那个论坛，但我不知道在哪里寻找....（如果你只是给出任何建议，除了ogc dokus之外，我甚至会很高兴）
我测试了它自己的服务器上两次，并点击：http：//giv-sos.uni-muenster.de：8080/52nSOSv3/
我的要求：

异常回应，我从服务器获取：

的exceptionCode =“InvalidRequest”是很明显的，但还是让我困惑，我无法找到与它线索的数独....
我很高兴每个答案！
