我正在嘗試在我的項目中實現HTTP客戶端，我無法登錄到我的帳戶，我得到了Forbidden !, IdHTTP工作正常，什麼是缺失或錯誤我的代碼？如何在Delphi中使用HTTP客戶端登錄到網站xe
NetHTTPClient1性質：
Connectiontimeout = 30000
AllowCookies = True
HandleRedirects = True
UserAgent = Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.76 Mobile Safari/537.36
NetHTTPRequest1屬性：
Method String = POST
URL = https://www.instagram.com/accounts/web_create_ajax/attempt/
代碼：
procedure TForm2.Button1Click(Sender: TObject);
var
Params : TStrings;
lHTTP: TIdHTTP;
IdSSL : TIdSSLIOHandlerSocketOpenSSL;
N: Integer;
Token,email,S: string;
Reply: TStringList;
Cookie: TIdCookie;
begin
lHTTP := TIdHTTP.Create(nil);
try
IdSSL := TIdSSLIOHandlerSocketOpenSSL.Create(lHTTP);
IdSSL.SSLOptions.Method := sslvTLSv1;
IdSSL.SSLOptions.Mode := sslmClient;
lHTTP.IOHandler := IdSSL;
lHTTP.ReadTimeout := 30000;
lHTTP.HandleRedirects := True;
lHTTP.Request.UserAgent := 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.76 Mobile Safari/537.36';
lHTTP.Get('https://www.instagram.com', TStream(nil));
Cookie := lHTTP.CookieManager.CookieCollection.Cookie['csrftoken', 'www.instagram.com'];
if Cookie <> nil then
Token := Cookie.Value;
finally
end;
try
Params := TStringList.Create;
Params.Add('username=' +'myusername');
Params.Add('password=' + 'mypassword');
NetHTTPClient1.CustomHeaders['X-CSRFToken'] := Token;
NetHTTPClient1.CustomHeaders['X-Instagram-AJAX'] := '1';
NetHTTPClient1.CustomHeaders['X-Requested-With'] := 'XMLHttpRequest';
NetHTTPClient1.CustomHeaders['Referer'] := 'https://www.instagram.com/';
Memo1.Lines.Add(NetHTTPRequest1.Post('https://www.instagram.com/accounts/login/ajax/', Params).StatusText);
finally
end;
///login with IdHTTP///Wroks//
try
lHTTP.Request.CustomHeaders.Values['X-CSRFToken'] := Token;
lHTTP.Request.CustomHeaders.Values['X-Instagram-AJAX'] := '1';
lHTTP.Request.CustomHeaders.Values['X-Requested-With'] := 'XMLHttpRequest';
lHTTP.Request.Referer := 'https://www.instagram.com/';
lHTTP.Request.ContentType := 'application/x-www-form-urlencoded';
lHTTP.Request.UserAgent := 'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.76 Mobile Safari/537.36';
Reply := lHTTP.Post('https://www.instagram.com/accounts/login/ajax/', Params);
Memo1.Lines.Add(Reply);
end;
那麼，對於初學者來說，你不能真正開始使用'TIdHTTP'登錄，然後用'TNetHTTPClient'完成登錄，它們不會像Cookie一樣共享彼此的狀態信息。如果您要顯示完整的適用於您的登錄的「TIdHTTP」代碼，然後有人可以幫助您將該登錄名轉換爲「TNetHTTPClient」，那將會更加有用。 –
