HeB-MobileCordova Advanced HTTP
Cordova / Phonegap plugin for communicating with HTTP servers. Supports iOS, Android and Browser.
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
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-httpUsage
Plain Cordova
This plugin registers a global object located at cordova.plugin.http.
With Ionic-native wrapper
Check the Ionic docs for how to use this plugin with Ionic-native.
Synchronous Functions
getBasicAuthHeader
This returns an object representing a basic HTTP Authorization header of the form {'Authorization': 'Basic base64encodedusernameandpassword'}
var header = cordova.plugin.http.getBasicAuthHeader('user', 'password');useBasicAuth
This sets up all future requests to use Basic HTTP authentication with the given username and password.
cordova.plugin.http.useBasicAuth('user', 'password');setHeader
Set a header for all future requests to a specified host. Takes a hostname, a header and a value (must be a string value).
cordova.plugin.http.setHeader('Hostname', 'Header', 'Value');You can also define headers used for all hosts by using wildcard character "*" or providing only two params.
cordova.plugin.http.setHeader('*', 'Header', 'Value');
cordova.plugin.http.setHeader('Header', 'Value');The hostname also includes the port number. If you define a header for www.example.com it will not match following URL http://www.example.com:8080.
// will match http://www.example.com/...
cordova.plugin.http.setHeader('www.example.com', 'Header', 'Value');
// will match http://www.example.com:8080/...
cordova.plugin.http.setHeader('www.example.com:8080', 'Header', 'Value');setDataSerializer
Set the data serializer which will be used for all future PATCH, POST and PUT requests. Takes a string representing the name of the serializer.
cordova.plugin.http.setDataSerializer('urlencoded');You can choose one of these:
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")utf8: send data as plain UTF8 encoded string in body (content type "plain/text")
This defaults to urlencoded. You can also override the default content type headers by specifying your own headers (see setHeader).
Caution: urlencoded does not support serializing deep structures whereas json does.
setRequestTimeout
Set how long to wait for a request to respond, in seconds.
cordova.plugin.http.setRequestTimeout(5.0);setFollowRedirect
Configure if it should follow redirects automatically. This defaults to true.
cordova.plugin.http.setFollowRedirect(true);getCookieString
Returns saved cookies (as string) matching given URL.
cordova.plugin.http.getCookieString(url);setCookie
Add a custom cookie. Takes a URL, a cookie string and an options object. See ToughCookie documentation for allowed options.
cordova.plugin.http.setCookie(url, cookie, options);clearCookies
Clear the cookie store.
cordova.plugin.http.clearCookies();Asynchronous Functions
These functions all take success and error callbacks as their last 2 arguments.
setServerTrustMode
Set server trust mode, being one of the following values:
default: default SSL trustship and hostname verification handling using system's CA certslegacy: use legacy default behavior (< 2.0.3), excluding user installed CA certs (only for Android)nocheck: disable SSL certificate checking and hostname verification, trusting all certs (meant to be used only for testing purposes)pinned: trust only provided certificates
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. Include your certificate in the www/certificates folder. All .cer files found there will be loaded automatically.
:warning: Your certificate must be DER encoded! If you only have a PEM encoded certificate read this stackoverflow answer. You want to convert it to a DER encoded certificate with a .cer extension.
// enable SSL pinning
cordova.plugin.http.setServerTrustMode('pinned', function() {
console.log('success!');
}, function() {
console.log('error :(');
});
// use system's default CA certs
cordova.plugin.http.setServerTrustMode('default', function() {
console.log('success!');
}, function() {
console.log('error :(');
});
// disable SSL cert checking, only meant for testing purposes, do NOT use in production!
cordova.plugin.http.setServerTrustMode('nocheck', function() {
console.log('success!');
}, function() {
console.log('error :(');
});disableRedirect (deprecated)
This function was deprecated in 2.0.9. Use "setFollowRedirect" instead.
setSSLCertMode (deprecated)
This function was deprecated in 2.0.8. Use "setServerTrustMode" instead.
enableSSLPinning (obsolete)
This function was removed in 2.0.0. Use "setServerTrustMode" to enable SSL pinning (mode "pinned").
acceptAllCerts (obsolete)
This function was removed in 2.0.0. Use "setServerTrustMode" to disable checking certs (mode "nocheck").
validateDomainName (obsolete)
This function was removed in v1.6.2. Domain name validation is disabled automatically when you set server trust mode to "nocheck".
removeCookies
Remove all cookies associated with a given URL.
cordova.plugin.http.removeCookies(url, callback);sendRequest
Execute a HTTP request. Takes a URL and an options object. This is the internally used implementation of the following shorthand functions (post, get, put, patch, delete, head, uploadFile and downloadFile). You can use this function, if you want to override global settings for each single request. Check the documentation of the respective shorthand function for details on what is returned on success and failure.
:warning: You need to encode the base URL yourself if it contains special characters like whitespaces. You can use encodeURI() for this purpose.
The options object contains following keys:
method: HTTP method to be used, defaults toget, needs to be one of the following values:get,post,put,patch,head,delete,upload,download
data: payload to be send to the server (only applicable onpost,putorpatchmethods)params: query params to be appended to the URL (only applicable onget,head,delete,uploadordownloadmethods)serializer: data serializer to be used (only applicable onpost,putorpatchmethods), defaults to global serializer value, see setDataSerializer for supported valuesresponseType: expected response type, defaults totext, needs to be one of the following values:text: data is returned as decoded string, use this for all kinds of string responses (e.g. XML, HTML, plain text, etc.)jsondata is treated as JSON and returned as parsed objectarraybuffer: data is returned as ArrayBuffer instanceblob: data is returned as Blob instance
timeout: timeout value for the request in seconds, defaults to global timeout valuefollowRedirect: enable or disable automatically following redirectsheaders: headers object (key value pair), will be merged with global valuesfilePath: file path(s) to be used during upload and download see uploadFile and downloadFile for detailed informationname: name(s) to be used during upload see uploadFile for detailed information
Here's a quick example:
const options = {
method: 'post',
data: { id: 12, message: 'test' },
headers: { Authorization: 'OAuth2: token' }
};
cordova.plugin.http.sendRequest('https://google.com/', options, function(response) {
// prints 200
console.log(response.status);
}, function(response) {
// prints 403
console.log(response.status);
//prints Permission denied
console.log(response.error);
});post
Execute a POST request. Takes a URL, data, and headers.
cordova.plugin.http.post('https://google.com/', {
test: 'testString'
}, {
Authorization: 'OAuth2: token'
}, function(response) {
console.log(response.status);
}, function(response) {
console.error(response.error);
});success
The success function receives a response object with 4 properties: status, data, url, and headers. status is the HTTP response code as numeric value. data is the response from the server as a string. url is the final URL obtained after any redirects as a string. headers is an object with the headers. The keys of the returned object are the header names and the values are the respective header values. All header names are lowercase.
Here's a quick example:
{
status: 200,
data: '{"id": 12, "message": "test"}',
url: 'http://example.net/rest'
headers: {
'content-length': '247'
}
}Most apis will return JSON meaning you'll want to parse the data like in the example below:
cordova.plugin.http.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 4 properties: status, error, url, and headers (url and headers being optional). status is a HTTP response code or an internal error code. Positive values are HTTP status codes whereas negative values do represent internal error codes. error is the error response from the server as a string or an internal error message. url is the final URL obtained after any redirects as a string. headers is an object with the headers. The keys of the returned object are the header names and the values are the respective header values. All header names are lowercase.
Here's a quick example:
{
status: 403,
error: 'Permission denied',
url: 'http://example.net/noperm'
headers: {
'content-length': '247'
}
}:warning: An enumeration style object is exposed as cordova.plugin.http.ErrorCode. You can use it to check against internal error codes.

}, { Authorization: 'OAuth2: token' }, function(response) {
console.log(response.status);
}, function(response) {
console.error(response.error);

console.log(entry.name);
// prints the filePath
console.log(entry.fullPath);
}, function(response) {
console.error(response.error);
