Indy 10 - IdHTTP.Get 引发“无法加载 SSL 库”

Question

In my application I am using IdHTTP.Get. A part of the code:

var
  IdHTTP: TIdHTTP;
begin
  IdHTTP := TIdHTTP.Create(nil);
  Output := IdHTTP.Get(url);
  ...
  IdHTTP.Free;

Using IdHTTP.Version gives me the version: 10.6.2.5263

I have downloaded the OpenSSL from here , both libeay32.dll and ssleay32.dll are in the same folder of my application.

This problem occured since I am using a new laptop with Windows 10. I hope someone can tell me how to solve this problem!

Answer 1

If you need to access an https url, you must add some code, to complete the creacion of the TidHTTP component.

Try use something like this:

// create components
HTTPs := Tidhttp.Create(nil);
IdSSL := TIdSSLIOHandlerSocket.Create(nil);
// try..finally for free
try
  // ini
  HTTPs.ReadTimeout := 30000;
  HTTPs.IOHandler := IdSSL;
  IdSSL.SSLOptions.Method := sslvTLSv1;
  IdSSL.SSLOptions.Method := sslvTLSv1;
  IdSSL.SSLOptions.Mode := sslmUnassigned;
  ...

You need to add IdSSLOpenSSL to uses clause.

Having 32 bit target platform for your application in a 64 bit system will also cause this problem. I don't know how to properly fix this but an easy way is to compile exe for same system your OS is.

Answer 3

I've exactly the same problem. Have you a solution to share ? My application worked with a previous version of Windows 10 and not now. But there is no problem if I compile in 32 bit. The problem occurs only when compiling in 64 bit.

Thanks
