发送POST服务器？ （instagram api） [英] Send POST serverside? (instagram api)

问题描述

查看 http://instagram.com/developer/authentication/ - 推荐的方式通信是服务器端。

Looking at http://instagram.com/developer/authentication/ - The recommended way of communication is serverside.

我理解我如何做step1和step2。但在第3步他们希望我POST数据直接服务器？ （我理解我如何做一个post请求从jQuery）但是，甚至可以直接从PHP / CodeIgniter？

I understand how I do step1 and step2. But in step3 they want me POST data directly serverside? (I understand how I could do a post request from jQuery) But is it even possible to do directly from PHP/CodeIgniter?

这基本上是step3：

This is basically step3:

在上一步中，您将收到一个代码，您将有
进行交换，以便为用户接收access_token 。为了使
进行这个交换，你只需要POST这个代码，连同
一些应用程序标识参数到我们的access_token端点。

In the previous step, you’ll have received a code which you’ll have to exchange in order to receive an access_token for the user. In order to make this exchange, you simply have to POST this code, along with some app identification parameters to our access_token endpoint.

我有这些信息:(来自Instagram的回复）

I have all this info: (from response from Instagram)

client_id: your client id
client_secret: your client secret
grant_type: authorization_code is currently the only supported value
redirect_uri: the redirect_uri you used in the authorization request. Note: this has to be the same value as in the authorization request.
code: the exact code you received during the authorization step.

推荐答案

后端可以像浏览器一样做POST。

A backend can do a POST just like the browser. Much of the internet is server-to-server communication in this manner.

以下是PHP中的一个示例POST请求（使用Curl）

Here's an example POST request in PHP (using Curl)

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,"http://www.example.com/site.html");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "postvar1=value1&postvar2=value2");

// receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec ($ch);

curl_close ($ch);

另一种设置POST参数而不是手动创建param字符串的方法：

An alternative way to set the POST parameters instead of manually creating the param string:

curl_setopt($ch, CURLOPT_POSTFIELDS, 
         http_build_query(array('postvar1' => 'value1')));
