Cordova Advanced HTTP
Cordova / Phonegap plugin for communicating with HTTP servers. Supports iOS and Android. This is a fork of Wymsee's Cordova-HTTP plugin.
Advantages over Javascript requests
- Background threading - all requests are done in a background thread.
- Handling of HTTP code 401 - read more at Issue CB-2415.
- 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-advanced-http
cordova plugin add cordova-plugin-advanced-http
Usage
Without AngularJS
This plugin registers a global object located at cordova.plugin.http.
With 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.
Synchronous 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");
setDataSerializer
Set the data serializer which will be used for all future POST and PUT requests. Takes a string representing the name of the serializer.
cordovaHTTP.setDataSerializer("urlencoded");
You can choose one of these two:
urlencoded: send data as url encoded content in body (content type "application/x-www-form-urlencoded")json: send data as JSON encoded content in body (content type "application/json")
Caution: urlencoded does not support serializing deep structures whereas json does.
clearCookies
Clear the cookie store.
cordovaHTTP.clearCookies();
Asynchronous 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, data, 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);
});
put
Execute a PUT request. Takes a URL, data, and headers. See the post documentation for details on what is returned on success and failure.
delete
Execute a DELETE request. Takes a URL, parameters, and headers. See the post documentation for details on what is returned on success and failure.
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);
});
