CORS - Cross-Origin Resource Sharing. How to configure?

צריך להוסיף ל web.config של Web API:

<system.webServer>
    <httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Headers" value="*" />
        <add name="Access-Control-Allow-Methods" value="*" />
      </customHeaders>
    </httpProtocol>
  </system.webServer>

וב Client:

fetch('http://localhost/WebApi/api/values', {
      method: 'POST', // or 'PUT'
      headers: {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Headers': '*',
        'Content-Type': 'application/json;charset=UTF-8'
      },
      body: JSON.stringify(data),
    }).then((response) => response.json())
      .then((data) => {this.title = data;});
