[英]Get http web request send error in c# code
我正在使用 HttpWebRequest 來獲取響應並將 stream 作為 json 文檔保存到我的驅動器上。 當我通過 Postman 進行測試時,一切正常,但是當我運行下面的 C# 代碼時出現錯誤。
C#:
string url = "https://myapi.com/api/v1/city";
var result = "";
string json = string.Empty;
HttpWebRequest hwrequest = WebRequest.CreateHttp(url);
hwrequest.Method = "GET";
hwrequest.Accept = "application/json";
hwrequest.Credentials = new System.Net.NetworkCredential("user", "password");
using (var response = hwrequest.GetResponse())
using (var stream = new StreamReader(response.GetResponseStream()))
{
result = stream.ReadToEnd();
}
JavaScriptSerializer jss = new JavaScriptSerializer
{
MaxJsonLength = Int32.MaxValue
};
json = jss.Serialize(result);
using (StreamWriter sw = new StreamWriter(File.Create(@"C:\temp\city.json")))
{
sw.Write(json);
}
錯誤:
基礎連接已關閉。 發送時發生意外錯誤。
API 看起來像立即顯示 json 而不是“發送”響應的那些。
你可以試試這個嗎?
在此之后,您將能夠以任何您喜歡的方式使用 json 格式的 output。
private string apiRead()
{
string xml = "";
string remoteUrl = "https://myapi.com/api/v1/city";
WebClient myWebClient = new WebClient();
string credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes(webUser + ":" + webPassw)); // if you use basic authorization in base64 format
myWebClient.Headers[HttpRequestHeader.Authorization] = string.Format("Basic {0}", credentials);
try
{
byte[] myDataBuffer = myWebClient.DownloadData(remoteUrl);
xml = Encoding.ASCII.GetString(myDataBuffer);
}
catch (Exception)
{
xml = "";
}
return xml;
}
