Cordova Ajax requests Cross-domain problem collation

first, by default, Cordova cannot directly use Ajax to request access to other data in the page.

Exception 1:

Ripple.js:51 refused to connect to ' Http://localhost:59201/api/category/getlistbyparent? Projectcode=lc_app_v1 ' because it violates the following Content Security Policy directive: "Default-src ' self ' data:gap: Https://ssl.gstatic.com ' Unsafe-eval ' ". Note that ' connect-src ' was not explicitly set, so ' default-src ' is used as a fallback.

Solution:

page-level configuration , allowing the page's connect to request the other data

Set the Content-security-policy CONNECT-SRC *;

Examples are as follows:

<meta http-equiv= "Content-security-policy" content= "default-src ' self ' data:gap:https://ssl.gstatic.com ' Unsafe-eval '; Style-src ' self ' unsafe-inline '; MEDIA-SRC *;CONNECT-SRC *; " >

Exception 2:

and exception 3 issues with Internet Server error:

Ser/get%3fjson rippleapi.herokuapp.com

Solution:

Ripple Configuration

Ipple settings There is a cross Domain Proxy in the upper right corner, with three choices, Disabled, local, and remote, which can be literally seen to be disabled, locally and remotely accessible, if you are accessing the native API. It is generally set to disabled. If you access the remote host's API, it is generally set to either remote or disabled.

Exception 4: Common Ajax cross-domain issues, this is primarily server-side configuration, can be consulted: Enable ASP. WEBAPI support for JSONP and Cors cross-domain access
