我正在制作一个类似邮递员的应用程序,我正在尝试使用 HttpWebRequest
实现基本身份验证,但我总是以403 forbidden error
结尾,我想这意味着我做错了什么。
我目前正在使用WebHeaderCollection
来存储我的标头。我像这样构建我的授权标头:
法典:
private WebHeaderCollection AddAuthorization(WebHeaderCollection wc)
{
if (expanderBasique.IsExpanded && !String.IsNullOrEmpty(BasiqueUserName.Text) && !String.IsNullOrEmpty(BasiquePassword.Password))
{
String username = BasiqueUserName.Text.Trim();
String password = BasiquePassword.Password.Trim();
String encoded = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("ISO-8859-1").GetBytes(username + ":" + password));
wc.Add("Authorization", "Basic " + encoded);
}
return wc;
}
然后我将我的集合链接到 HttpWebRequest:
法典:
private async Task<WebResponse> ExecuteHttpWebRequest()
{
var selectedMethode = Methode.SelectedItem as TextBlock;
string method = selectedMethode.Text;
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(Query.Text);
WebHeaderCollection myWebHeaderCollection = webRequest.Headers;
myWebHeaderCollection = BuildHeaderCollection(myWebHeaderCollection);
myWebHeaderCollection = AddAuthorization(myWebHeaderCollection);
webRequest.PreAuthenticate = true;
webRequest.Method = method;
if (webRequest.Method == "POST" || webRequest.Method == "PUT" || webRequest.Method == "PATCH")
{
byte[] data = Encoding.ASCII.GetBytes(Body.Text);
webRequest.ContentLength = data.Length;
using (var stream = webRequest.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
}
return await webRequest.GetResponseAsync();
}
我使用自己的凭据使用 GitHub API 尝试此代码:https://api.github.com/user
使用邮递员或 restER 等其他应用程序,我得到了我想要的结果,但我总是以我自己的 403 错误告终。
我真的很想坚持使用HttpWebRequest。
我尝试了堆栈溢出的各种解决方案,但没有成功:这里或这里
编辑 :
根据FaizanRabbani的评论,我通过将UserAgent属性设置为httpwebrequest来解决问题:
法典:
private async Task<WebResponse> ExecuteHttpWebRequest()
{
var selectedMethode = Methode.SelectedItem as TextBlock;
string method = selectedMethode.Text;
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(Query.Text);
WebHeaderCollection myWebHeaderCollection = webRequest.Headers;
myWebHeaderCollection = BuildHeaderCollection(myWebHeaderCollection);
myWebHeaderCollection = AddAuthorization(myWebHeaderCollection);
webRequest.PreAuthenticate = true;
webRequest.Method = method;
webRequest.UserAgent = "something";
if (webRequest.Method == "POST" || webRequest.Method == "PUT" || webRequest.Method == "PATCH")
{
byte[] data = Encoding.ASCII.GetBytes(Body.Text);
webRequest.ContentLength = data.Length;
using (var stream = webRequest.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
}
return await webRequest.GetResponseAsync();
}
