@nativescript-community/https

The definitive way to hit HTTP based APIs in Nativescript.

Easily integrate the most reliable native networking libraries with the latest and greatest HTTPS security features.

Android: version 4.x using okhttp 4.x changing minSDKVersion to 21! If lower needed stick to 3.x

Plugin version 2.0.0 bumps AFNetworking on iOS to 4.0.0 which no longer relies on UIWebView. Make sure to run pod repo update to get the latest AFNetworking pod on your development machine.

A drop-in replacement for the default http module.

FAQ

What the flip is SSL pinning and all this security mumbo jumbo?

How to make your apps more secure with SSL pinning.

Do I have to use SSL pinning?

No. This plugin works out of the box without any security configurations needed. Either way you'll still benefit from all the features listed above.

Installation

tns plugin add @nativescript-community/https

Examples

Hitting an API using GET method

import * as Https from '@nativescript-community/https';
Https.request({
    url: 'https://httpbin.org/get',
    method: 'GET',
    timeout: 30, // seconds (default 10)
})
    .then(function (response) {
        console.log('Https.request response', response);
    })
    .catch(function (error) {
        console.error('Https.request error', error);
    });

Configuration

Installing your SSL certificate

Create a folder called assets in your projects app folder like so <project>/app/assets. Using chrome, go to the URL where the SSL certificate resides. View the details then drag and drop the certificate image into the assets folder.

Enabling SSL pinning

import { knownFolders } from 'file-system';
import * as Https from '@nativescript-community/https';
let dir = knownFolders.currentApp().getFolder('assets');
let certificate = dir.getFile('httpbin.org.cer').path;
Https.enableSSLPinning({ host: 'httpbin.org', certificate });

Once you've enabled SSL pinning you CAN NOT re-enable with a different host or certificate file.

Disabling SSL pinning

import * as Https from '@nativescript-community/https';
Https.disableSSLPinning();

All requests after calling this method will no longer utilize SSL pinning until it is re-enabled once again.

useLegacy

There is a new option called useLegacy. You can set of every request options. When using that option the request will behave more like {N} http module.

• the content returned by a request is not the resulting string but an object. It follows HTTPContent format for the most part. You can call toJSON or toFile. The only difference is that toFile returns a Promise<File> which means that it is async and run in a background thread!
• an error return a content too allowing you to read its content.

Cookie

By default basic Cookie support is enabled to work like in {N} http module. In the future more options will be added

Enabling Cache

import { knownFolders, path } from '@nativescript/core/file-system';
import * as Https from '@nativescript-community/https';
Https.setCache({
    diskLocation: path.join(knownFolders.documents().path, 'httpcache'),
    diskSize: 10 * 1024 * 1024, // 10 MiB
});

/// later on when calling your request you can use the cachePolicy option

Multipart form data

If you set the Content-Type header to "multipart/form-data" the request body will be evaluated as a multipart form data. Each body parameter is expected to be in this format:

{
	data: any
    parameterName: string,
    fileName?: string
    contentType?: string
}

if fileName and contentType are set then data is expected to be either a NSData on iOS or a native.Array<number> on Android.

Options

export interface HttpsSSLPinningOptions {
    host: string;
    certificate: string;
    allowInvalidCertificates?: boolean;
    validatesDomainName?: boolean;
    commonName?: string;
}
import { HttpRequestOptions } from 'tns-core-modules/http';
export interface HttpsRequestOptions extends HTTPOptions {
    useLegacy?: boolean;
    cachePolicy?: 'noCache' | 'onlyCache' | 'ignoreCache';
    onProgress?: (current: number, total: number) => void;
}

SSLPinning Option	Description
host: string	This must be the request domain name eg sales.company.org.
commonName?: string	Default: options.host, set if certificate CN is different from the host eg *.company.org (Android specific)
certificate: string	The uri path to your .cer certificate file.
allowInvalidCertificates?: boolean	Default: false. This should always be false if you are using SSL pinning. Set this to true if you're using a self-signed certificate.
validatesDomainName?: boolean	Default: true. Determines if the domain name should be validated with your pinned certificate.

Requests Option	Description
useLegacy?: boolean	Default: false. [IOS only] set to true in order to get the response data (when status >= 300)in the content directly instead of response.body.content.
`cachePolicy?: 'noCache'	'onlyCache'
onProgress?: (current: number, total: number) => void	[IOS only] Set the progress callback.

Webpack / bundling

Since you're probably shipping a certificate with your app (like our demo does), make sure it's bundled by Webpack as well. You can do this by adding the certificate(s) with the CopyWebpackPlugin.

iOS Troubleshooting

Please educate yourself on iOS's App Transport Security before starting beef!

If you try and hit an https route without adding it to App Transport Security's whitelist it will not work! You can bypass this behavior by adding the following to your projects Info.plist:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

This plugin does not add NSAllowsArbitraryLoads to your projects Info.plist for you.

Android troubleshooting

If you app crashes with a message that it's doing too much networkin on the main thread, then pass the option allowLargeResponse with value true to the request function.
