问题描述
我目前有一个使用 ServiceBusTrigger 绑定的天蓝色函数
[ServiceBusTrigger("%TopicName%", "%SubscripionName%", Connection = "MyConnection")]字符串 catclogueEventMsgs、ILogger 日志、ExecutionContext 上下文)
使用这个 local.settings.json 文件
"值": {…我的连接":端点=sb://testxxxxxxxxxxxxxxxxxx订阅名称":测试订阅名称""主题名称": "测试主题名称",}
如何在 appsettings.json 文件中表示这一点.会像下面这样吗?
"值": {我的连接":端点=sb://testxxxxxxxxxxxxxxxxxx订阅名称":测试订阅名称""主题名称": "测试主题名称",}
我可以使用例如MySubs"对象来代替使用Values"对象吗?
"MySubs": {我的连接":端点=sb://testxxxxxxxxxxxxxxxxxx订阅名称":测试订阅名称""主题名称": "测试主题名称",}
如果可以使用上述设置,我如何在 ServiceBusTrigger 绑定中表示?我会改成这个吗?
[ServiceBusTrigger("%MySubs.TopicName%", "%MySubs.SubscripionName%", Connection = "MySubs.MyConnection")]字符串 catclogueEventMsgs、ILogger 日志、ExecutionContext 上下文)
您确实可以读取 Values
数组之外的设置,如下所示:
WeatherApiConfig.cs
公共类 WeatherApiConfig{公共字符串 WeatherApiUrl { 获取;放;}公共字符串 WeatherApiKey { 获取;放;}}

Azure Functions V2 的新功能,
I currently have an azure function using the ServiceBusTrigger binding
[ServiceBusTrigger("%TopicName%", "%SubscripionName%", Connection = "MyConnection")]
string catclogueEventMsgs, ILogger log, ExecutionContext context)
which uses this local.settings.json file
"Values": {
…
"MyConnection": "Endpoint=sb://testxxxxxxxxxxxxxxxxxx
"SubscriptionName": "testsubscriptionName"
"TopicName": "testtopicName",
}
How do I represent this in the appsettings.json file. Will it be like the below?
"Values": {
"MyConnection": "Endpoint=sb://testxxxxxxxxxxxxxxxxxx
"SubscriptionName": "testsubscriptionName"
"TopicName": "testtopicName",
}
Instead of using a "Values" object can I use eg "MySubs" object like the below?
"MySubs": {
"MyConnection": "Endpoint=sb://testxxxxxxxxxxxxxxxxxx
"SubscriptionName": "testsubscriptionName"
"TopicName": "testtopicName",
}
If its possible to use the above settings, how do I represent this in the ServiceBusTrigger binding? would i change it to this?
[ServiceBusTrigger("%MySubs.TopicName%", "%MySubs.SubscripionName%", Connection = "MySubs.MyConnection")]
string catclogueEventMsgs, ILogger log, ExecutionContext context)
You CAN indeed read settings outside the Values
array as follows:
WeatherApiConfig.cs
public class WeatherApiConfig
{
public string WeatherApiUrl { get; set; }
public string WeatherApiKey { get; set; }
}
New for Azure Functions V2, we have an appropriate way to handle DI as shown below:
Startup.cs
[assembly: FunctionsStartup(typeof(BlazingDemo.Api.Startup))]
namespace BlazingDemo.Api
{
public class Startup : FunctionsStartup
{
public override void Configure(IFunctionsHostBuilder builder)
{
var config = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("local.settings.json", optional: true, reloadOnChange: true)
.AddEnvironmentVariables()
.Build();
var apiConfig = new WeatherApiConfig();
config.Bind(nameof(WeatherApiConfig), apiConfig);
builder.Services.AddSingleton(apiConfig);
builder.Services.AddHttpClient();
}
}
}
Local.settings.json
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"FUNCTIONS_WORKER_RUNTIME": "dotnet"
},
"WeatherApiConfig": {
"WeatherApiUrl": "http://api.openweathermap.org/data/2.5/weather",
"WeatherApiKey": "**removed**"
}
}
Note: The key for me was to add
.SetBasePath(Directory.GetCurrentDirectory())
inStartup.cs
since it couldn't find the file without it.
In production I use the function app's Application Settings
section to configure these two properties as follows:
