C＃-Azure函数问题

Question

我是编码新手，并不熟悉C＃。 但是，我有一个PHP脚本，试图将其转换为C＃以在Azure Function中使用，它将每15分钟触发一次。 我具有代码的第一部分和功能，它可以在Azure Function控制台中编译并产生成功，但不会在输出中提供结果。 下面是代码：

using System;
using System.Collections.Generic;
using System.Web;
using System.Net;
using System.Net.Http;
using System.Text;
using System.Text.RegularExpressions;

public static void Run(TimerInfo myTimer, TraceWriter log)
{
log.Info($"C# Timer trigger function executed at: {DateTime.Now}");    
}
{
using (var httpClientHandler = new HttpClientHandler())
{
httpClientHandler.AllowAutoRedirect = false;

using (var httpClient = new HttpClient(httpClientHandler))    
{
var response = 
httpClient.GetAsync("https://auth.bullhornstaffing.com/oauth/authorize?
client_id=****type=code&username=*****&password=*****&action=Login").Result;
if (response.StatusCode == HttpStatusCode.Found)
{
var redirectUrl = response.Headers.Location;
var startIndex = redirectUrl.Query.IndexOf("code=") + 5;
var endIndex = redirectUrl.Query.IndexOf("&", startIndex);
var authorizationCode = (redirectUrl.Query.Substring(startIndex, endIndex - 
startIndex));
}
}
}
    }

如果删除varauthorizationCode，则会收到错误消息，提示它没有名称空间，如果返回它或响应，则不会得到任何输出。

帮助将不胜感激。

Answer 1

httpClient.GetAsync是一个异步语句，这意味着代码将继续运行而无需等待webrequest完成。 等待GetAsync，然后您可以继续：

var task = httpClient.GetAsync("https://auth.bullhornstaffing.com/oauth/authorize?client_id=****type=code&username=*****&password=*****&action=Login");
task.Wait();
var response = task.Result;

还有两个括号太多（第12和13行），我想您想访问httpContent的ContentLocation吗？

也许那是正确的：

using System;
using System.Net;
using System.Net.Http;

public static void Run(TimerInfo myTimer, TraceWriter log)
{
    log.Info($"C# Timer trigger function executed at: {DateTime.Now}");    

    using (var httpClientHandler = new HttpClientHandler())
    {
        httpClientHandler.AllowAutoRedirect = false;

        using (var httpClient = new HttpClient(httpClientHandler))
        {
            log.Info("get async...");
            var task = httpClient.GetAsync("https://auth.bullhornstaffing.com/oauth/authorize?client_id=****type=code&username=*****&password=*****&action=Login");
            task.Wait();

            var response = task.Result;
            var httpContent = response.Content;
            log.Info("Result: " + httpContent.Headers.ContentLocation);

            if (response.StatusCode == HttpStatusCode.Found)
            {
                var redirectUrl = httpContent.Headers.ContentLocation;
                var startIndex = redirectUrl.Query.IndexOf("code=") + 5;
                var endIndex = redirectUrl.Query.IndexOf("&", startIndex);
                var authorizationCode = (redirectUrl.Query.Substring(startIndex, endIndex - startIndex));
            }
        }
    }
}
