Speichern einer HTTP-Antwort auf eine Datei

Question

Ich kann die HTTP-Antwort nicht in einer Textdatei speichern. Ich kann eine Anfrage machen und ich kann sehen, dass es durchläuft und ich bekomme die Antwort, die ich will, aber es speichert nicht in einer Datei. Mein Code ist unten, ich habe die andere Lösung, die ich ausprobiert habe, auskommentiert.

protected void Button1_Click(object sender, EventArgs e) 
    { 
     string input = TextBox1.Text; 
     string sURL; 
     sURL = "http://api.urlvoid.com/api1000/key/host/" + input + "/"; 
     HttpWebRequest wrGETURL = (HttpWebRequest)WebRequest.Create(sURL); 
     HttpWebResponse wrResponse = (HttpWebResponse)wrGETURL.GetResponse(); 
     StreamWriter SW = new StreamWriter(@"C:\Users\user\Desktop\API_Call_Test.txt"); 
     Stream DataStream = wrResponse.GetResponseStream(); 
     StreamReader SR = new StreamReader(DataStream); 
     string AllResponse = SR.ReadToEnd(); 
     //var file = File.Open(@"C:\Users\user\Desktop\API_Call_Test.txt", FileMode.Create); 
     SW.Write(DataStream); 
     //DataStream.CopyTo(file); 
     wrResponse.Close(); 

    } 

Die Wireshark Analyse des TCP-Stream:

GET /api1000/key/host/mo.gov/        HTTP/1.1 
    Host: api.urlvoid.com 
    Connection: Keep-Alive 

    HTTP/1.1 200 OK

Answer 1

Nun, das so etwas wie unten wäre. Ich denke du kannst es gut anpassen.

string url = "http://www.google.com"; 
string file = "response.txt"; 
string content = string.Empty; 

// set up request/response 
var request = (HttpWebRequest) WebRequest.Create(url); 
var response = (HttpWebResponse) request.GetResponse(); 
var stream = response.GetResponseStream(); 

// read response content 
using (var reader = new StreamReader(stream ?? new MemoryStream(), Encoding.UTF8)) 
    content = reader.ReadToEnd(); 

// write to file on desktop 
File.WriteAllText(
    Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), file), 
    content, 
    Encoding.UTF8);

Sie sind nicht die Anforderungsdaten zu schreiben und Sie müssen einen Leser-Stream-Daten zu lesen:

protected void Button1_Click(object sender, EventArgs e) 
{ 
    string input = TextBox1.Text; 
    string sURL; 
    sURL = "http://api.urlvoid.com/api1000/key/host/" + input + "/"; 
    HttpWebRequest wrGETURL = (HttpWebRequest)WebRequest.Create(sURL); 
    using (Stream stm = wrGETURL.GetRequestStream()) 
    { 
     using (StreamWriter stmw = new StreamWriter(stm)) 
     { 
      stmw.Write(input); 
     } 
    } 
    using (StreamReader responseReader = new StreamReader(wrGETURL.GetResponse().GetResponseStream())) 
    { 
     string resultString = responseReader.ReadToEnd(); 
     if (File.Exists(@"C:\Users\user\Desktop\API_Call_Test.txt")) 
      File.Delete(@"C:\Users\user\Desktop\API_Call_Test.txt"); 
     File.Create(@"C:\Users\user\Desktop\API_Call_Test.txt").Close(); 
     File.WriteAllText(@"C:\Users\user\Desktop\API_Call_Test.txt", resultString); 
    } 
}
