• reason why , post calls failed ?

  you had missed cordova whitelist plugin.it required make or post request. installation command

  cordova plugin add cordova-plugin-whitelist

  navigation whitelist

controls urls webview can navigated to. applies top-level navigations only.

quirks: on android applies iframes non-http(s) schemes.

by default, navigations file:// urls, allowed. allow others urls, must add tags config.xml:

 <!-- allow links example.com --> <allow-navigation href="http://example.com/*" />  <!-- wildcards allowed protocol, prefix      host, or suffix path --> <allow-navigation href="*://*.example.com/*" />  <!-- wildcard can used whitelist entire network,      on http , https.      *not recommended* --> <allow-navigation href="*" />  <!-- above equivalent these 3 declarations --> <allow-navigation href="http://*/*" /> <allow-navigation href="https://*/*" /> <allow-navigation href="data:*" />
