具有React JS和ASP Web API的CORS

Question

我在使用React JS和ASP Web API创建应用程序时遇到了问题 Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:53248/api/home/saveData. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

我的React组件代码是

submitData(event) {
    fetch("http://localhost:53248/api/home/saveData", {
        method: 'POST',
        headers: {
            'Accept': 'application/json',
            'Content-Type': 'application/json'
        },
        body: JSON.stringify({
            // userName: this.state.userName,
            // password: this.state.password,
            email: this.state.email
        })
    }).then((Response) => Response.json())
        .then((findresponse) => {
            if (findresponse.result == 'authenticated')
                alert("1");
            else
                alert("2");
    })
}

此问题的任何帮助。
