我开始修补Azure SignalR,但遇到了带有negiotate触发器的问题。我遵循了this官方Microsoft指南:
这里输入我的代码:
local.settings.json
{
"IsEncrypted": false,
"Values": {
"AzureSignalRConnectionString": "Endpoint=https://my.service.signalr.net;AccessKey=myKey=;Version=1.0;",
"FUNCTIONS_WORKER_RUNTIME": "node"
},
"Host": {
"LocalHttpPort": 7071,
"CORS": "*",
"CORSCredentials": true
}
}
function.json
{
"disabled": false,
"bindings": [
{
"authLevel": "anonymous",
"type": "httpTrigger",
"direction": "in",
"methods": [
"get"
],
"name": "req",
"route": "negotiate"
},
{
"type": "http",
"direction": "out",
"name": "res"
},
{
"type": "SignalRConnectionInfo",
"name": "connectionInfo",
"hubName": "jitsi",
"ConnectionStringSetting": "Endpoint=https://my.service.signalr.net;AccessKey=myKey;Version=1.0;",
"direction": "in"
}
]
}
index.js
module.exports = async function (context, req, connectionInfo) {
context.res.body = connectionInfo;
};
它在本地运行良好(不幸的是,指南结束了)。但是,如果我访问协商http-trigger的URL,则会收到“内部服务器错误500”。日志包含以下输出。
2020-04-23T08:47:32 Welcome, you are now connected to log-streaming service. The default timeout is 2 hours. Change the timeout with the App Setting SCM_LOGSTREAM_TIMEOUT (in seconds).

Unable to resolve the value for property 'SignalRConnectionInfoAttribute.ConnectionStringSetting'. Make sure the setting exists and has a valid value.
您可以在我的代码中看到,我确实提供了ConnectionStringSetting
。
有人建议,这是由于ConnectionStringSetting
中的大小写为'C'。据说其他人要编辑local.settings.json。这些都对我没有影响,我找不到有关此问题的任何有用信息。
编辑1:我设定为"hubName":"jitsi"
。 jitsi
是我的SignalR服务的名称。如在“ jitsi.service.signalr.net”中。我不确定这是否正确。也许那是问题的一部分?
编辑2:我尝试没有为ConnectionStringSetting
设置任何值(以便将其设置为默认值)。给了我同样的错误。我还完全删除了local.settings.json
的所有内容,然后重新部署以查看会发生什么。与以前相同的行为。我的猜测是,该服务仅将文件用于本地使用(因此命名)。因此,在local.settings.json
为空的情况下,没有其他地方可以定义AzureSignalRConnectionString
的值。我做了一些挖掘,显然(根据this线程),您应该在[]下定义它
'配置'->'应用程序设置'
所以我用]创建了一个新设置>
名称:Azure__SignalR__ConnectionString
值:myMaskedConnectionString
导致以下错误:
The SignalR Service connection string must be set either via an 'AzureSignalRConnectionString' app setting, via an 'AzureSignalRConnectionString' environment variable, or directly in code via SignalROptions.ConnectionString or SignalRConnectionInfoAttribute.ConnectionStringSetting.
我开始修补Azure SignalR,但遇到了带有negiotate触发器的问题。我遵循了这份官方的Microsoft指南:这是我的代码:local.settings.json {“ IsEncrypted”:false,“ ...
我找到了解决此问题的方法:
起初我很困惑,以为local.settings.json
将用作功能的实时/非本地版本的配置。事实并非如此。它仅用于本地执行(可以通过文件名猜测)
