[英]How do i make an async GET with authentication in c#?
I need to make this code async, also visual studio is telling me that the HttpWebResponse that I'm using is deprecated, though it's the only way I can make the data download work:我需要使此代码异步,而且 visual studio 告诉我我正在使用的 HttpWebResponse 已被弃用,尽管这是我可以使数据下载工作的唯一方法:
for (int i = 2; i <= Pages; i++)
{
var request = (HttpWebRequest)WebRequest.Create("https://MYAPIPATH=" + i);
request.Headers.Add("Authorization", "Basic " + encoded);
request.Method = "GET";
request.ContentType = "application/x-www-form-urlencoded";
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
var MyResult = JsonConvert.DeserializeObject<RootObject_DataFeed>(responseString);
string Products = JsonConvert.SerializeObject(MyResult.Products);
File.WriteAllText(pathProducts + i + ".json", Products);
using (Stream file = File.OpenWrite(pathProducts + i + ".json"))
{
wresp.GetResponseStream().CopyTo(file);
}
}
What I want to do is to make the download faster downloading multiple files at once (since there are around 3000 Pages)我想要做的是让下载速度更快,一次下载多个文件(因为大约有 3000 页)
I would recomend you to use http client that supports auth mechanism.我建议您使用支持身份验证机制的 http 客户端。 eg
例如
string authUserName = "user";
string authPassword = "password";
string url = "https://someurl.com";
var httpClient = new HttpClient();
var authToken = Encoding.ASCII.GetBytes($"{authUserName}:{authPassword}");
httpClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(authToken));
var response = await httpClient.GetAsync(url);
response.EnsureSuccessStatusCode();
return await response.Content.ReadAsStringAsync();
and then you can dod the same actions with your string content然后你可以用你的字符串内容做同样的动作
