程序模拟HTTP请求

string strContent = "client_id=client&client_secret=secret&grant_type=client_credentials";
HttpContent content = new StringContent(strContent, Encoding.UTF8, "application/x-www-form-urlencoded");

public async void GetResponse()
{
HttpClient client = new HttpClient();
Url = "http://xxxx";
ClientInfo info = new ClientInfo();
Json = JsonConvert.SerializeObject(info, Settings);
HttpContent content = new StringContent(Json, Encoding.UTF8, "application/json");
using (var response = await client.PostAsync(Url, content))
{
var result = await response.Content.ReadAsStringAsync();
Console.WriteLine(result);
}
}

using (HttpClient client = new HttpClient())
{
using (var response = client.GetAsync(url))
{
response.Result.EnsureSuccessStatusCode();
var name = response.Result.Content.Headers.ContentDisposition.FileName.Replace("\"", "");
var buff = response.Result.Content.ReadAsByteArrayAsync().Result;
string filename = Path.Combine(path, name);
using (FileStream fs = new FileStream(filename, FileMode.OpenOrCreate))
{
fs.Write(buff, 0, buff.Length);
}
}
}
