Когда я отправляю запрос в свою функцию Azure, я получаю следующее исключение:

Внутреннее исключение System.NullReferenceException, обработанное в System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw: at AlidadeUtilities.OnUnzipHttpTriggered +d__0.MoveNext (AlidadeUtilities, Версия = 1.0.0.0, Культура = нейтральная, PublicKeyToken = nullAlidadeUtilities, Версия = 1.0.0.0, Культура = нейтральная, PublicKeyToken = null: C: \ tfs \ Corolar \ Alidade \ AlidadeUtilities \ DEV \ AlidadeUtilgeHitPlay_Up \ UI\ OnUnzipHttpTriggered.csAlidadeUtilities, версия = 1.0.0.0, культура = нейтральная, PublicKeyToken = ноль: 26)

Строка 26 моего кода:

var requestBody = new StreamReader(req.Body).ReadToEnd();

Окружающий код:

public static class OnUnzipHttpTriggered
{
    [FunctionName("OnUnzipHttpTriggered")]
    public static async Task<IActionResult> Run(
        [HttpTrigger(AuthorizationLevel.Function, "post", Route = null)] HttpRequest req,
        ILogger log)
    {
        log.LogInformation("C# HTTP trigger function processed a request.");

        var requestBody = new StreamReader(req.Body).ReadToEnd();
        var data = JsonConvert.DeserializeObject<ZipFileMetaData>(requestBody);
        var storageAccount =
        CloudStorageAccount.Parse(Environment.GetEnvironmentVariable("StorageConnectionString"));

Что я делаю не так?

Примером запроса может быть POST с телом JSON.

Как можноreq.Body быть нулевым?

вот полное сообщение об ошибке:

Первый изменяет класс запроса на HttpRequestMessage вместо просто HttpRequest

. Тело сообщения должно быть прочитано с использованием

var msg = req.Content.ReadAsStringAsync().Result;

Нет прямого req.Body, который высвязывает доступ, и поэтому вы получаете исключение нулевой ссылки.Если вам нужны message и messageHeaders, тогда десериализируйте сообщение в и вы получите оба значения.

  class Content{
    public dynamic MessageBody { get; set; }
    public dynamic MessageHeader { get; set; }
  }
  var message = JsonConvert.DeserializeObject<Content>(msg);
  var messageContext = message.MessageHeader;

Пример триггера также можно увидеть в docs
