我試圖提出「registerSensor」請求。看到下面的xml文件。 但不幸的是，我只收到一個異常，關於一個NULL GET請求。 什麼混淆我最深的是，我發送和POST方法讀取的事實。從服務器請求（ogc）「Sensor Observation Service」（傳感器觀察服務）請求
我知道這個問題可能不適合那個論壇，但我不知道在哪裏尋找....（如果你只是給出任何建議，除了ogc dokus之外，我甚至會很高興）
我測試了它自己的服務器上兩次，並點擊：http：//giv-sos.uni-muenster.de：8080/52nSOSv3/
我的要求：

異常回應，我從服務器獲取：

的exceptionCode =「InvalidRequest」是很明顯的，但還是讓我困惑，我無法找到與它線索的數獨....
我很高興每個答案！
有沒有人有想法？ – user972851
