【问题描述】:
以下代码请求 OAuth2 令牌。它适用于 Indy 10.0.52,但适用于 Indy 10 SVN 5412,由于请求凭据无效,它会生成 400 Bad Request 错误。
WXYZUserID := Trim( GetSettingsValue( mySQLQuery, wcsWXYZUserID, ''));
WXYZPassword := Trim( GetSettingsValue( mySQLQuery, wcsWXYZPassword, ''))
WXYZSecret := Trim( GetSettingsValue( mySQLQuery, wcsWXYZSecret, ''));
OAuthURL := Trim( GetSettingsValue( mySQLQuery, wcsOAuthURL, ''));
WxyzHttp := TIdHttp.Create(nil);
Serial := TStringList.Create;
if (WXYZUserID <> '') and (WXYZPassword <> '') and (WXYZSecret <> '') then
Serial.Add('grant_type=password&username=' + WXYZUserID + '&password=' + WXYZPassword )
Else
Serial.Add('grant_type=password&username=****-*****&password=***************');
Output := TMemoryStream.Create;
Serial.SaveToStream(Output);
WxyzHttp.ConnectTimeout := 60000;
IdLogFile := TIdLogFile.Create;
IdLogFile.Filename := 'Logs/WxyzHTTP' + FOrmatDateTime('yyyymmdd_hhnnsszzz',now) + '.log';
IdLogFile.Active := True;
IdSSLIOHandlerSocketOpenSSL1 := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
IdSSLIOHandlerSocketOpenSSL1.SSLOptions.Method := sslvSSLv23;
IdSSLIOHandlerSocketOpenSSL1.Intercept := IdLogFile;
WxyzHttp.IOHandler := IdSSLIOHandlerSocketOpenSSL1;
if (WXYZUserID <> '') and (WXYZPassword <> '') and (WXYZSecret <> '') then
WxyzHttp.Request.CustomHeaders.Values['Authorization'] := 'Basic ' + WXYZSecret
Else
WxyzHttp.Request.CustomHeaders.Values['Authorization'] := 'Basic ****************************************************************';
WxyzHttp.Request.ContentType := 'application/x-www-form-urlencoded; charset="utf-8"';
Try
Token := WxyzHttp.Post( OAuthURL, Output );
Except
On E: Exception do
Begin
DbgWebCatLog( wcmtDbg, 'GetSerialToken', E.ClassName + ' error raised, with message: ' + E.Message, '' );
Token := '';
end;
end;
我添加了代码来捕获 IdLogFile 日期。 Indy 10.0.52 版本的日志包含以下包含凭据的行。
Sent 05/01/2017 18:34:35: grant_type=password&username=*************_*****-*****&password=***}%25**(**(***
出于安全考虑,我已将所有字母数字字符替换为“*”。 “%25”字符原本是实际密码中的“%”。有些东西将原来的“%”翻译成“%25”,但没有改变任何其他特殊字符。
对 Indy 10 SVN 5412 日志的初始检查检测到来自服务器的消息,指示存在无效的请求凭据。此外,对应于上述行中的所有特殊字符表明所有特殊字符都已被编码。 grant_type、用户名和密码是使用 tStringList 呈现的,我发现它会导致 urlencoding。我更改了代码以使用流呈现相同的数据,现在没有任何内容被编码;甚至“%”都没有被翻译成“%25”,我继续收到无效的请求凭据消息。
所以我的问题是,为什么 Indy 10.0.52 只会将“%”字符转换为“%25”,我如何在 Indy 10 SVN 5412 中复制这种行为?
以下是有效的 Indy 10.0.52 版本的完整日志。
