1. Configuring Access URLs in nginx.conf

When you access api1.yingtrader.com/boquote, the boquote.php code is executed.

650) this.width=650; "src=" Http://s4.51cto.com/wyfs02/M00/82/3A/wKiom1dOs3XisFbWAAD-ptQhK4g266.png "title=" Picture 10.png "alt=" Wkiom1dos3xisfbwaad-ptqhk4g266.png "/>

2. Nginx to implement AJAX cross-domain requests

To enable cross-domain requests on Nginx , you need to add the add_header access-control* directive.

As shown below:

location/{

Add_header ' access-control-allow-origin ' http://other.subdomain.com ';

Add_header ' access-control-allow-credentials ' true ';

Add_header ' Access-control-allow-methods ' POST, GET, OPTIONS, PUT, DELETE, HEAD ';

...

...

The rest of your configuration here

...

...

}

Comments are as follows:

First instruction: Authorizing requests from other.subdomain.com

Second instruction: When the flag is true, responds to whether the request can be exposed

The third day directive: Specifies the method of the request, which can be get,POST , etc.

If you need to allow access from any domain, you can configure this:

Add_header ' Access-control-allow-origin ' *;

3. writing the PHP code

⑴ get POST parameters via $_post

Error_reporting (e_all^e_notice^e_warning);

... .. ... ..

$login = $_post[' UserAccount ');

$volume = $_post[' volume ');

... .. ... ..

⑵ return JSON data

... .. ... ..

$ret = Array ();

if (' OK ' = = $resarr [0]) {

$ret = [' success ' = ' tradesuccess '];

}else{

$ret = [' Error ' = ' tradefail '];

}

echo Json_encode ($ret);
