Question

这里sendasync()函数是如何使用的我不知道。

我使用foreach循环然后每次获取手机号码和消息相同但主要问题是SendAsync是如何使用我不知道。

[WebMethod(true)]
public static string SendMessage(List<int> ids, string message)
{
    foreach (var id in ids)
    {
        HttpClient client = new HttpClient();
        using (mapsEntityDataContext db = new mapsEntityDataContext())
        {
            tbl_inq edit = db.tbl_inqs.SingleOrDefault(x => x.Inq_Id == id);
            var mobile = edit.Contact;

            client.BaseAddress = new Uri("http://sms.hspsms.com/sendSMS?username=hspdemo&message=" + message + "&sendername=HSPSMS&smstype=TRANS&numbers=" + mobile + "&apikey=66e12418-8b67-4c2a-9a08-4fd459bfa84c");
            client.SendAsync();
        }
        //client.SendAsync();
    }

    return "sucess";
}

有多种方法可以执行GET和POST请求：

方法A：logging.level.root=OFF

目前首选方法。异步。运行.NET 4.5;可通过NuGet获得的其他平台的便携版本。

使用HttpClient POST

System.Net.Http;

}

GET

using (var client = new HttpClient())
{
    var values = new Dictionary<string, string>
    {
   { "thing1", "hello" },
   { "thing2", "world" }
};

var content = new FormUrlEncodedContent(values);

var response = await client.PostAsync("http://www.example.com/recepticle.aspx", content);

var responseString = await response.Content.ReadAsStringAsync();

方法B：第三方库

RestSharp

经过试验和测试的库，用于与REST API交互。便携。可通过NuGet获取。

Flurl.Http

较新的图书馆提供流畅的API和测试助手。引擎盖下的HttpClient。便携。可通过NuGet获取。

  using (var client = new HttpClient())
{
    var responseString = await   client.GetStringAsync("http://www.example.com/recepticle.aspx");
}

POST

using Flurl.Http;

GET

var responseString = await "http://www.example.com/recepticle.aspx"
    .PostUrlEncodedAsync(new { thing1 = "hello", thing2 = "world" })
    .ReceiveString();

方法C：遗产

var responseString = await "http://www.example.com/recepticle.aspx"
    .GetStringAsync();

POST

using System.Net;
using System.Text;  // for class Encoding

GET

var request = (HttpWebRequest)WebRequest.Create("http://www.example.com/recepticle.aspx");

var postData = "thing1=hello";
    postData += "&thing2=world";
var data = Encoding.ASCII.GetBytes(postData);

request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;

using (var stream = request.GetRequestStream())
{
    stream.Write(data, 0, data.Length);
}

var response = (HttpWebResponse)request.GetResponse();

var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

方法D：WebClient（现在也是遗产）

var request = (HttpWebRequest)WebRequest.Create("http://www.example.com/recepticle.aspx");

var response = (HttpWebResponse)request.GetResponse();

var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

POST

using System.Net;
using System.Collections.Specialized;

GET

using (var client = new WebClient())
{
    var values = new NameValueCollection();
    values["thing1"] = "hello";
    values["thing2"] = "world";

    var response = client.UploadValues("http://www.example.com/recepticle.aspx", values);

    var responseString = Encoding.Default.GetString(response);
}

如何发送消息？
