Perfect solution to api and WebService cross-origin problems, apiwebservice cross-Origin

In many cases, cross-origin problems occur when you call a webapi through ajax. If you want to use ajax to call the same WebService, you also need an Interface Cross-origin problem. The solution is as follows:

1. IIS configuration

Open IIS and select the published webapi or WebService. Select website> HTTP Response Header> Add .. The procedure is as follows:

The name and value to be added are

<add name="Access-Control-Allow-Methods" value="OPTIONS,POST,GET"/><add name="Access-Control-Allow-Headers" value="x-requested-with,Content-Type"/><add name="Access-Control-Allow-Origin" value="*" />

2. Add tags directly in web. config.

<system.webServer>　　
Remember. Only one method can be used. Otherwise, an error is returned.
