cordovaHTTP

Cordova / Phonegap plugin for communicating with HTTP servers. Supports iOS and Android.

Advantages over Javascript requests

• Background threading - all requests are done in a background thread.
• SSL Pinning - read more at LumberBlog.

Updates

Please check CHANGELOG.md for details about updating to a new version.

Installation

The plugin conforms to the Cordova plugin specification, it can be installed using the Cordova / Phonegap command line interface.

phonegap plugin add cordova-plugin-http

cordova plugin add cordova-plugin-http

Usage

AngularJS

This plugin creates a cordovaHTTP service inside of a cordovaHTTP module. You must load the module when you create your app's module.

var app = angular.module('myApp', ['ngRoute', 'ngAnimate', 'cordovaHTTP']);

You can then inject the cordovaHTTP service into your controllers. The functions can then be used identically to the examples shown below except that instead of accepting success and failure callback functions, each function returns a promise. For more information on promises in AngularJS read the AngularJS docs. For more info on promises in general check out this article on html5rocks. Make sure that you load cordova.js or phonegap.js after AngularJS is loaded.

Not AngularJS

This plugin registers a cordovaHTTP global on window

Sync Functions

getBasicAuthHeader

This returns an object representing a basic HTTP Authorization header of the form {'Authorization': 'Basic base64encodedusernameandpassword'}

var header = cordovaHTTP.getBasicAuthHeader("user", "password");

useBasicAuth

This sets up all future requests to use Basic HTTP authentication with the given username and password.

cordovaHTTP.useBasicAuth("user", "password");

setHeader

Set a header for all future requests. Takes a header and a value.

cordovaHTTP.setHeader("Header", "Value");

Async Functions

These functions all take success and error callbacks as their last 2 arguments.

enableSSLPinning

Enable or disable SSL pinning. This defaults to false.

To use SSL pinning you must include at least one .cer SSL certificate in your app project. You can pin to your server certificate or to one of the issuing CA certificates. For ios include your certificate in the root level of your bundle (just add the .cer file to your project/target at the root level). For android include your certificate in your project's platforms/android/assets folder. In both cases all .cer files found will be loaded automatically. If you only have a .pem certificate see this stackoverflow answer. You want to convert it to a DER encoded certificate with a .cer extension.

As an alternative, you can store your .cer files in the www/certificates folder.

cordovaHTTP.enableSSLPinning(true, function() {
    console.log('success!');
}, function() {
    console.log('error :(');
});

acceptAllCerts

Accept all SSL certificates. Or disable accepting all certificates. This defaults to false.

cordovaHTTP.acceptAllCerts(true, function() {
    console.log('success!');
}, function() {
    console.log('error :(');
});

validateDomainName

Whether or not to validate the domain name in the certificate. This defaults to true.

cordovaHTTP.validateDomainName(false, function() {
    console.log('success!');
}, function() {
    console.log('error :(');
});

post

Execute a POST request. Takes a URL, parameters, and headers.

success

The success function receives a response object with 3 properties: status, data, and headers. Status is the HTTP response code. Data is the response from the server as a string. Headers is an object with the headers. Here's a quick example:

{
    status: 200,
    data: "{'id': 12, 'message': 'test'}",
    headers: {
        "Content-Length": "247"
    }
}

Most apis will return JSON meaning you'll want to parse the data like in the example below:

cordovaHTTP.post("https://google.com/", {
    id: 12,
    message: "test"
}, { Authorization: "OAuth2: token" }, function(response) {
    // prints 200
    console.log(response.status);
    try {
        response.data = JSON.parse(response.data);
        // prints test
        console.log(response.data.message);
    } catch(e) {
        console.error("JSON parsing error");
    }
}, function(response) {
    // prints 403
    console.log(response.status);
    
    //prints Permission denied 
    console.log(response.error);
});

failure

The error function receives a response object with 3 properties: status, error and headers. Status is the HTTP response code. Error is the error response from the server as a string. Headers is an object with the headers. Here's a quick example:

{
    status: 403,
    error: "Permission denied",
    headers: {
        "Content-Length": "247"
    }
}

get

Execute a GET request. Takes a URL, parameters, and headers. See the post documentation for details on what is returned on success and failure.

cordovaHTTP.get("https://google.com/", {
    id: 12,
    message: "test"
}, { Authorization: "OAuth2: token" }, function(response) {
    console.log(response.status);
}, function(response) {
    console.error(response.error);
});

uploadFile

Uploads a file saved on the device. Takes a URL, parameters, headers, filePath, and the name of the parameter to pass the file along as. See the post documentation for details on what is returned on success and failure.

cordovaHTTP.uploadFile("https://google.com/", {
    id: 12,
    message: "test"
}, { Authorization: "OAuth2: token" }, "file:///somepicture.jpg", "picture", function(response) {
    console.log(response.status);
}, function(response) {
    console.error(response.error);
});

downloadFile

Downloads a file and saves it to the device. Takes a URL, parameters, headers, and a filePath. See post documentation for details on what is returned on failure. On success this function returns a cordova FileEntry object.

cordovaHTTP.downloadFile("https://google.com/", {
    id: 12,
    message: "test"
}, { Authorization: "OAuth2: token" }, "file:///somepicture.jpg", function(entry) {
    // prints the filename
    console.log(entry.name);
    
    // prints the filePath
    console.log(entry.fullPath);
}, function(response) {
    console.error(response.error);
});
