这是该函数的代码,非常简单:
[FunctionName("negotiate")]
public static SignalRConnectionInfo Run(
[HttpTrigger(AuthorizationLevel.Anonymous)]
HttpRequest req,
[SignalRConnectionInfo(
ConnectionStringSetting = "Endpoint=https://myowntestserver.service.signalr.net;AccessKey=mymaskedaccesskey=;Version=1.0;",
HubName = "tracking")]
SignalRConnectionInfo connectionInfo)
{
return connectionInfo;
}
在Visual Studio 2017上运行此代码时,出现以下错误消息:
[2019-03-27 3:39:14 PM]错误索引方法'negotiate'
[2019-03-27 3:39:14 PM] Microsoft.Azure.WebJobs.Host:错误索引方法 '谈判'。 Microsoft.Azure.WebJobs.Host:无法解析该值 属性“ SignalRConnectionInfoAttribute.ConnectionStringSetting”。 确保设置存在并且具有有效值。
local.settings.json文件如下:
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"FUNCTIONS_WORKER_RUNTIME": "dotnet"
}
}
这是host.json文件:
{
"version": "2.0"
}
项目文件包含以下nuget包:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netcoreapp2.2</TargetFramework>
<AzureFunctionsVersion>v2</AzureFunctionsVersion>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.Azure.WebJobs.Extensions.ServiceBus" Version="3.0.3" />
<PackageReference Include="Microsoft.Azure.WebJobs.Extensions.SignalRService" Version="1.0.0" />
<PackageReference Include="Microsoft.NET.Sdk.Functions" Version="1.0.26" />
</ItemGroup>
<ItemGroup>
<None Update="host.json">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</None>
<None Update="local.settings.json">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
<CopyToPublishDirectory>Never</CopyToPublishDirectory>
</None>
</ItemGroup>
</Project>
在所有这些看起来正确的配置之后,不确定为什么我们会收到上面引用的错误消息。
答案 0 :(得分:0)
通过按照以下示例更新local.settings.json文件来解决此问题:
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"AzureWebJobsDashboard": "UseDevelopmentStorage=true",
"AzureSignalRConnectionString": "Endpoint=Endpoint=https://myowntestserver.service.signalr.net;AccessKey=mymaskedaccesskey=;Version=1.0;""
},
"Host": {
"LocalHttpPort": 7071,
"CORS": "*"
}
}
此外,应从属性中删除SignalRConnectionInfo.ConnectionStringSetting。
