Question

您好，我想从其api运行推送应用程序中心。但是我不知道如何制作正确的格式。

我想通过此api https://appcenter.ms/api/v0.1/apps/KacangIjo/ShopDiaryApp/push/notifications

postasync

标头需要的是： X-API-Token =“ {api token}”和内容类型=“ application / json”

对于正文（内容），我要输入：

{
    "notification_content" : {
        "name" : "Campaign Name",
        "title" : "Expired Warning",
        "body" : "You have items that almost expired"
    }
}

我很难为HttpClient编写正确的格式。我试过了，没有工作..

Content = new Content
{
   Name = "Campaign Name",
   Title = "Expired Warning",
   Body = "You have items that almost expired"
};
using (var client = new HttpClient { Timeout = TimeSpan.FromSeconds(30) })
{
   var myContent = JsonConvert.SerializeObject(data);
   client.DefaultRequestHeaders.Add("X-API-Token", "{my api token}");
   client.DefaultRequestHeaders.Accept.Add(new 
   MediaTypeWithQualityHeaderValue("application/json"));
   var builder = new UriBuilder(new Uri("https://appcenter.ms/api/v0.1/apps/KacangIjo/ShopDiaryApp/push/notifications"));
   HttpResponseMessage response = await client.PostAsync(builder.Uri, content);
};

但是我知道这是代码：

 {
        "notification_content" : {
            "name" : "Campaign Name",
            "title" : "Expired Warning",
            "body" : "You have items that almost expired"
        }
    }

与转换json格式的方法不同：

Content = new Content
{
    Name = "Campaign Name",
    Title = "Expired Warning",
    Body = "You have items that almost expired"
};

可以为我提供正确的序列化Json格式吗？以及httpclient标头和正文的正确格式？我已经找到了很多样本，但是仍然对我想要的样本一无所知。非常感谢您的帮助：）

您需要按照与所需的JSON类似的方式来构造对象。

创建如下所示的类。

public class NotificationContent
{
    [JsonProperty("name")]
    public string Name { get; set; }

    [JsonProperty("title")]
    public string Title { get; set; }

    [JsonProperty("body")]
    public string Body { get; set; }
}

public class PostObject
{
    [JsonProperty("notification_content")]
    public NotificationContent NotificationContent { get; set; }
}

上面是正确的结构，现在当您调用JsonConvert.SerializeObject时，您的json将是

 {
    "notification_content" : {
        "name" : "Campaign Name",
        "title" : "Expired Warning",
        "body" : "You have items that almost expired"
    }
}

下面是http呼叫的代码

using (var client = new HttpClient { Timeout = TimeSpan.FromSeconds(30) })
    {
        PostObject postObject = new PostObject
        {
            NotificationContent = new NotificationContent
            {
                Name = "Campaign Name",
                Title = "Expired Warning",
                Body = "You have items that almost expired"
            }
        };

        var myContent = JsonConvert.SerializeObject(postObject);
        client.DefaultRequestHeaders.Add("X-API-Token", "{my api token}");
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

        var builder = new UriBuilder(new Uri("https://appcenter.ms/api/v0.1/apps/KacangIjo/ShopDiaryApp/push/notifications"));

        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, builder.Uri);
        request.Content = new StringContent(myContent, Encoding.UTF8, "application/json");//CONTENT-TYPE header

        HttpResponseMessage response = await client.SendAsync(request);
    };

具有自定义标头和主体C＃的application / json的HttpClient postasync
