获取“ facebook代码”以从服务器端获取长期访问令牌。 Django的

Question

I'm trying to follow this doc to get a long-lived user token. (see "Generating Long-Lived User Tokens from Server-Side Long-Lived Tokens")

The diagram is quite explicit, and I thought it should be easy.

But the problem comes when I try to get the "code."

As you can see, this should be the request:

https://graph.facebook.com/oauth/client_code?access_token=...&client_secret=...&redirect_uri=...&client_id=...

But the problem is that since I'm on the Server side, I'm not able to redirect the user since that's a client work. (Isn't it?)

So, since I got this error:

{
  "error": {
    "message": "Missing redirect_uri parameter.",
    "type": "OAuthException",
    "code": 191,
    "fbtrace_id": "EqPakhHX9i6"
  }
}

I tried this:

&redirect_uri=https://www.google.com/& (to see if it eats that URI)

But no chance.

I was looking for similar questions, but people use to use the client side, and I don't have any access to the Client. Actually, the client is waiting for this code from me, as the diagram shows.

So, I don't have any idea how I can do it.

Maybe someone here had the same problem.

仅将下一个网址与cURL一起使用：

https://graph.facebook.com/oauth/access_token?grant_type=fb_exchange_token&client_id={client-id}&client_secret={secret-id}&fb_exchange_token={short-token}
