|
### Generates an asynchronous resolver function from a [PAC file][pac-wikipedia]
|

|
|
|
||
|
|
This module accepts a JavaScript String of code, which is meant to be a
|
||
|
|
[PAC proxy file][pac-wikipedia], and returns a generated asynchronous
|
||
|
|
`FindProxyForURL()` function.
|
||
|
|
|
||
|
|
|
||
|
|
Installation
|
||
|
|
------------
|
||
|
|
|
||
|
|
Install with `npm`:
|
||
|
|
|
||
|
|
``` bash
|
||
|
|
$ npm install pac-resolver
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
Example
|
||
|
|
-------
|
||
|
|
|
||
|
|
Given the PAC proxy file named `proxy.pac`:
|
||
|
|
|
||
|
|
``` js
|
||
|
|
function FindProxyForURL(url, host) {
|
||
|
|
if (isInNet(myIpAddress(), "10.1.10.0", "255.255.255.0")) {
|
||
|
|
return "PROXY 1.2.3.4:8080";
|
||
|
|
} else {
|
||
|
|
return "DIRECT";
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
You can consume this PAC file with `pac-resolver` like so:
|
||
|
|
|
||
|
|
``` js
|
||
|
|
var fs = require('fs');
|
||
|
|
var pac = require('pac-resolver');
|
||
|
|
|
||
|
|
var FindProxyForURL = pac(fs.readFileSync('proxy.pac'));
|
||
|
|
|
||
|
|
FindProxyForURL('http://foo.com/').then((res) => {
|
||
|
|
console.log(res);
|
||
|
|
// "DIRECT"
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|

### pac(String jsStr[, Object options]) → Function
|
||
|
|
|
||
|
|
Returns an asynchronous `FindProxyForURL()` function based off of the given JS
|
||
|
|
string `jsStr` PAC proxy file. An optional `options` object may be passed in which
|
||
|
|
respects the following options:
|
||
|
|
|
||
|
|
* `filename` - String - the filename to use in error stack traces. Defaults to `proxy.pac`.
|
||
|
|
* `sandbox` - Object - a map of functions to include in the sandbox of the
|
||
|
|
JavaScript environment where the JS code will be executed. i.e. if you wanted to
|
||
|
|
include the common `alert` function you could pass `alert: console.log`. For
|
||
|
|
async functions, you must set the `async = true` property on the function
|
||
|
|
instance, and the JS code will be able to invoke the function as if it were
|
||
|
|
synchronous.
