我在VS2017中创建了一个基本功能应用,并尝试运行 下面的问题。
Microsoft.Azure.WebJobs.Host:错误索引方法'Fun 章节1.运行'。 Microsoft.Azure.WebJobs.Host:无法绑定参数“ log”以键入TraceWriter。确保绑定支持参数类型。如果你是 使用绑定扩展名(例如ServiceBus,Timer等),确保已在启动代码(例如config)中调用了扩展名的注册方法。“
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.Azure.WebJobs.Host;
namespace FunctionAppLatest
{
public static class Function1
{
[FunctionName("Function1")]
public static async Task<HttpResponseMessage> Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)]HttpRequestMessage req, TraceWriter log)
{
log.Info("C# HTTP trigger function processed a request.");
// parse query parameter
string name = req.GetQueryNameValuePairs()
.FirstOrDefault(q => string.Compare(q.Key, "name", true) == 0)
.Value;
if (name == null)
{
// Get request body
dynamic data = await req.Content.ReadAsAsync<object>();
name = data?.name;
}
return name == null
? req.CreateResponse(HttpStatusCode.BadRequest, "Please pass a name on the query string or in the request body")
: req.CreateResponse(HttpStatusCode.OK, "Hello " + name);
}
}
}
答案 0 :(得分:3)
Azure中的Function 2.0不再使用TraceWriter
。
请替换为ILogger log
您需要使用log.info
代替log.LogInformation("C# HTTP trigger function processed a request.");
