遵循本教程chain-azure-functions-data-using-bindings,使用 JavaScript 时它可以工作,但是使用 .net 作为运行时堆栈创建了一个新的函数应用程序,添加了所需的 cosmos db 映射,当使用 https等查询参数发送 GET 请求时://azurefuncurl?code=abc&id=docs appinsights 显示 azure 函数/主机由于 System.InvalidOperationException 而无法启动
尝试通过官方文档:azure-functions/configInput-Usage,没有运气
函数.json
{
"bindings": [
{
"authLevel": "function",
"name": "req",
"type": "httpTrigger",
"direction": "in",

}
运行.csx
#r "Newtonsoft.Json"
using System.Net;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Primitives;
using Newtonsoft.Json;
public static async Task<IActionResult> Run(HttpRequest req, ILogger log, dynamic bookmark)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string name = req.Query["id"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;
return name != null
? (ActionResult)new OkObjectResult($"Hello, {name}")
: new BadRequestObjectResult("Please pass a name on the query string or in the request body");
}
异常消息:
Error indexing method 'Functions.find-bookmark' Unable to resolve binding parameter 'id'. Binding expressions must map to either a value provided by the trigger or a property of the value the trigger is bound to, or must be a system binding expression (e.g. sys.randguid, sys.utcnow, etc.).
