Iot Hub 连接字符串在 azure-iot-sdk-c 示例中不起作用
Iot Hub connection string not working in azure-iot-sdk-c samples
我在 raspberry pi 3，raspbian OS 工作，我正在使用 azure-iot-sdk-c
我遵循了此处的 github 说明：https://github.com/Azure/azure-iot-sdk-c，我下载并正确构建了 iothub_client/samples 文件夹中的所有示例
错误是，当我将连接字符串放在 iothub_client_sample_http.c
这里：
static const char* connectionString = "[device connection string]";
和运行它，我得到很多这样的错误：
Error: Time:Mon Dec 19 14:23:36 2016
File:/home/pi/Desktop/azure-iot-sdk-c/c-utility/adapters/httpapi_curl.c
Func:HTTPAPI_ExecuteRequest Line:576 Failure in HTTP communication:

File:/home/pi/Desktop/azure-iot-sdk-c/iothub_client/src/iothubtransporthttp.c
Func:DoEvent Line:1626 unexpected HTTP status code (401)
这是我的连接结构：
static const char* connectionString = "HostName=<myiothub>;DeviceId=<mydevice>;SharedAccessKey=<myaccesskey>";
如果我直接使用 Azure 门户提供的字符串，为什么会出现 401？
我已经尝试了每个连接字符串（hubowner、服务和设备），但仍然给我 401 :C
我生成了 SAS 密钥并将其用作连接字符串，一切正常。
static const char* connectionString ="HostName=<myiothub>;CredentialType=SharedAccessSignature;DeviceId=<mydevice>;SharedAccessSignature=SharedAccessSignature sr=<iothub>&sig=<saskey>&se=<time>&skn=device"
的预构建版本生成了 SAS
这是有效的，因为，如 Control access to IoT Hub 中所述：
The only way that IoT Hub authenticates a specific device is using the
device identity symmetric key. In cases when a shared access policy is
used to access device functionality, the solution must consider the
component issuing the security token as a trusted subcomponent.
