Question

这是我在sign-up.ts

中的代码

let link = "http://localhost/signup.php";
    this.http.post(link, signupdata)
      .subscribe(data => {
        console.log("Success");
      },error => {
        console.log("Error");
      });

当我提交表单时，我在控制台中收到以下错误

XMLHttpRequest cannot load http://localhost/signup.php. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8100' is therefore not allowed access.

帮我解决这个问题。

Answer 1

您可以通过安装Chrome扩展程序SUM and AVERAGE functions

来尝试

工作原理：

Allow-Control-Allow-Origin: *

注意：您必须在使用其他网站时禁用此功能。

Answer 2

将这些行放在signup.php脚本的顶部：

header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE');
header('Access-Control-Allow-Credentials: true');
