离子推送通知API在C＃中使用的WebAPI [英] Ionic push notification api in c# with WebApi

问题描述

我试图发送使用离子推送通知API推送通知，使用C＃与的WebAPI。
从离子网站蟒的例子是可以正常使用的，但我不能让它工作在C＃，尽管它似乎要求是相同的。
这是我的code：

I'm trying to send a push notification using the ionic push notifications api, using c# with WebApi. The python example from ionic website is working perfectly, but I can't get it working in c#, although it seems that the requests are the same. This is my code:

 using (var client = new HttpClient())
            {

                client.BaseAddress = new Uri("https://push.ionic.io/api/v1/");
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Add("X-Ionic-Application-Id", IONIC_APP_ID);
                //client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
                var keyBase64 = "Basic " + IONIC_PRIVATE_KEY_BASE_64;
                client.DefaultRequestHeaders.Add("Authorization", keyBase64);
                client.DefaultRequestHeaders.Add("Accept-Encoding", "identity");
                //client.DefaultRequestHeaders.Add("Content-Type", "application/json");


                var response = client.PostAsJsonAsync("push", json).Result;
                if (response.IsSuccessStatusCode)
                {
                    int a = 6;
                }
            }

我不断收到错误的请求（400），没有进一步的解释。

I keep getting bad request (400), with no further explanation.

推荐答案

确定，解决它！
问题是与Content-Type头的PostAsJsonAsync方式默认内容类型是应用/ JSON的;字符集= UTF-8，而API期待应用/ JSON

OK, solved it! The problem was with the Content-Type header, the "PostAsJsonAsync" method default content-type is "application/json; charset=utf-8", while the api is expecting "application/json".

本作品：

        using (var client = new HttpClient())
        {

            client.BaseAddress = new Uri(API_URL);
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Add("X-Ionic-Application-Id", IONIC_APP_ID);
            var keyBase64 = "Basic " + IONIC_PRIVATE_KEY_BASE_64;
            client.DefaultRequestHeaders.Add("Authorization", keyBase64);
            HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, api);
            request.Content = new StringContent(json, Encoding.UTF8, "application/json");
            var response = client.SendAsync(request).Result;                
        }

有关的清晰度，调用函数是：

For clarity, the calling function is :

public void Send(string regId, string msg, int notificationId)
    {
        dynamic data = new ExpandoObject();
        data.tokens = new List<string>() {regId};
        data.notification = new ExpandoObject() as dynamic;
        data.notification.alert = msg;

        string json = Newtonsoft.Json.JsonConvert.SerializeObject(data);
        log.InfoFormat("Sending notifcation to {0}, message is {1} ", regId, msg);
        SendToIonic("push", json);           

    }
