获取Http Post方法返回的值

Question

我的web api中有一个post方法,它返回一个字符串,我从客户端调用该方法.我如何获得返回的值.

发布方法

    public String Post(Models.SQNotificationDataAccessRepository.NotificationEntry notificationEntry)
    {
        String externalReferenceID = String.Empty;
        if (notificationEntry == null)
        {
            throw new HttpResponseException(HttpStatusCode.BadRequest);
        }

        externalReferenceID= dbTransactionLayer.PopulateEsiTable(notification);

        return externalReferenceID;
    }

客户

        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("http://localhost:12819/");
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));


            Notification notification = new Notification()
            {
                id = 102,
                To = new String[] { "jamesBond@yahoo.com", "cmsds@email.com" },
                Title = "Notification WebService Client Test",
                MessageBody = "The message body will go there",
                DelieveryType = "Email",
                Response = true
            };



            HttpResponseMessage response = await client.PostAsJsonAsync("api/NotificationEntry/Post",notification);
            var result = response;

            Console.WriteLine("Successfully delivered:" + result.ToString);
        }

Answer 1

PostAsJsonAsync返回一个HttpResponseMessage,该Content属性具有应包含响应主体的属性.所以你可能会这样做:

var response = await client.PostAsJsonAsync("api/NotificationEntry/Post",notification);
var result = await response.Content.ReadAsStringAsync();

Console.WriteLine("Successfully delivered:" + result);

然后result应该包含您正在寻找的价值.如果string返回的内容不是其他内容,result则会包含该内容的序列化版本.所以它可以被解析/反序列化/等.如所须.
