Linux下onvif客户端获取ipc摄像头 GetStreamUri：rtsp地址（h264、h265）

GetStreamUri：rtsp地址

鉴权：但是在使用这个接口之前是需要鉴权的。ONVIF协议规定，部分接口需要鉴权，部分接口不需要鉴权，在调用需要鉴权的接口时不使用鉴权，会导致接口调用失败。实现鉴权的方式之一可以调用gSOAP源码中的 soap_wsse_add_UsernameTokenDigest()函数。要安装依赖库OpenSSL

ps：一般情况是如果一开始用的是_tr2（h265），那么获取信息的时候应该就会一直用tr2（h265）通道。但是有些摄像头比较奇葩，一开始走的都是_tr2，也就是h265的通道（如get_profiles），但是在获取onvif的uri（rtsp地址）的时候本该走_tr2（h265）通道，却走了_trt（h264）的通道才能获取，我这个摄像头就是如此。

当然有些h265的摄像头走的是trt（h264）通道，并不会用到_tr2（h265）的通道。

编译：gcc -o test get_Uri_test.c stdsoap2.c soapC.c md5.c dom.c mecevp.c smdevp.c threads.c wsaapi.c wsseapi.c soapClient.c -I import/ -DWITH_OPENSSL -lssl -lcrypto -ldl -pthread

结果：
