proxy-verifier

Check that proxies are working, verify their anonymity level (transparent, anonymous, or elite), lookup their geographic location by IP address, check for other capabilities such as tunneling and available protocols (HTTP/S, SOCKS4/5).

testAll

testAll(proxy[, options], cb)

Runs all test methods for the given proxy. The options argument is passed through to every test method.

Usage:

var ProxyVerifier = require('proxy-verifier');

var proxy = {
    ipAddress: '127.0.0.1',
    port: 8888,
    protocol: 'http'
};

ProxyVerifier.testAll(proxy, function(error, result) {

    if (error) {
        // Some unusual error occurred.
    } else {
        // The result object will contain success/error information.
    }
});

Sample result:

{
    anonymityLevel: 'elite',
    protocols: {
        http: {
            ok: true
        }
    },
    tunnel: {
        ok: true
    }
}

testProtocol

testProtocol(proxy[, options], cb)

Check that the proxy works with the specified protocol. The options argument is passed through to the request() method which uses request.

Usage:

var ProxyVerifier = require('proxy-verifier');

var proxy = {
    ipAddress: '127.0.0.1',
    port: 8080,
    protocol: 'http'
};

ProxyVerifier.testProtocol(proxy, function(error, result) {

    if (error) {
        // Some unusual error occurred.
    } else {
        // The result object will contain success/error information.
    }
});

Sample result when the proxy is working:

{
    ok: true
}

Sample result when the proxy is not working:

{
    ok: false,
    error: {
        message: 'socket hang up',
        code: 'ECONNRESET'
    }
}

testProtocols

testProtocols(proxy[, options], cb)

Check that the proxy works with the specified protocols. The options argument is passed through to the request() method which uses request.

Usage:

var ProxyVerifier = require('proxy-verifier');

var proxy = {
    ipAddress: '127.0.0.1',
    port: 8080,
    protocols: ['http', 'https']
};

ProxyVerifier.testProtocols(proxy, function(error, results) {

    if (error) {
        // Some unusual error occurred.
    } else {
        // The results object contains a result object for each protocol.
    }
});

Sample results when the proxy is working for all its protocols:

{
    http: {
        ok: true
    },
    https: {
        ok: true
    }
}

Sample results when the proxy is not working for any of the protocols:

{
    http: {
        ok: false,
        error: {
            message: 'socket hang up',
            code: 'ECONNRESET'
        }
    },
    https: {
        ok: false,
        error: {
            message: 'socket hang up',
            code: 'ECONNRESET'
        }
    }
}

testAnonymityLevel

testAnonymityLevel(proxy[, options], cb)

Check the anonymity level of the proxy. The options argument is passed through to the request() method which uses request.

Usage:

var ProxyVerifier = require('proxy-verifier');

var proxy = {
    ipAddress: '127.0.0.1',
    port: 8080,
    protocol: 'http'
};

ProxyVerifier.testAnonymityLevel(proxy, function(error, anonymityLevel) {

    if (error) {
        // Some unusual error occurred.
    } else {
        // anonymityLevel will be a string equal to "transparent", "anonymous", or "elite".
    }
});

Anonymity levels explained:

• transparent - The proxy does not hide the requester's IP address.
• anonymous - The proxy hides the requester's IP address, but adds headers to the forwarded request that make it clear that the request was made using a proxy.
• elite - The proxy hides the requester's IP address and does not add any proxy-related headers to the request.

testTunnel

testTunnel(proxy[, options], cb)

Check to see if the proxy supports HTTP tunneling. The options argument is passed through to the request() method which uses request.

Usage:

var ProxyVerifier = require('proxy-verifier');

var proxy = {
    ipAddress: '127.0.0.1',
    port: 8888,
    protocol: 'http'
};

ProxyVerifier.testTunnel(proxy, function(error, result) {

    if (error) {
        // Some unusual error occurred.
    } else {
        // The result object will contain success/error information.
    }
});

Sample result when the proxy supports tunneling:

{
    ok: true
}

Sample result when the proxy does not support tunneling:

{
    ok: false,
    error: {
        message: 'socket hang up',
        code: 'ECONNRESET'
    }
}

test

Use this method to create your custom tests. Example usage:

ProxyVerifier.test(proxy, {
    testUrl: 'https://www.google.com/?q=test',
    testFn: function(data, status, headers) {

        // Check the response data, status, and headers.

        // Throw an error if the test failed.
        throw new Error('Test failed!');

        // Do nothing if the test passed.
    }
}, function(error, results) {
    // Do something with error or results.
});

Contributing

There are a number of ways you can contribute:

• Improve or correct the documentation - All the documentation is in this readme.md file. If you see a mistake, or think something should be clarified or expanded upon, please submit a pull request
• Report a bug - Please review existing issues before submitting a new one; to avoid duplicates. If you can't find an issue that relates to the bug you've found, please create a new one.
• Request a feature - Again, please review the existing issues before posting a feature request. If you can't find an existing one that covers your feature idea, please create a new one.
• Fix a bug - Have a look at the existing issues for the project. If there's a bug in there that you'd like to tackle, please feel free to do so. I would ask that when fixing a bug, that you first create a failing test that proves the bug. Then to fix the bug, make the test pass. This should hopefully ensure that the bug never creeps into the project again. After you've done all that, you can submit a pull request with your changes.

Before you contribute code, please read through at least some of the source code for the project. I would appreciate it if any pull requests for source code changes follow the coding style of the rest of the project.

Now if you're still interested, you'll need to get your local environment configured.

Configure Local Environment

Step 1: Get the Code

First, you'll need to pull down the code from GitHub:

git clone https://github.com/chill117/proxy-verifier.git

Step 2: Install Dependencies

Second, you'll need to install the project dependencies as well as the dev dependencies. To do this, simply run the following from the directory you created in step 1:

npm install

Tests

This project includes an automated regression test suite. To run the tests:

npm test
