起源的“http：// localhost”的已被阻止通过CORS政策错误笨只是，我认为这是关于配置页

Question

我收到了如下的错误路径：

origin 'http://localhost' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost' is therefore not allowed access. 

此错误时才会发生该设计集成在codeigniter中。

Answer 1

您需要添加标题在您requested页：

// headers 
    header("Access-Control-Allow-Origin: *"); 
    header("Access-Control-Allow-Methods: POST"); 
    header("Access-Control-Allow-Headers: Origin, Methods, Content-Type"); 

编辑

在 codeigniter

：

$this->output 
     ->set_content_type("Access-Control-Allow-Origin: *") 
     ->set_content_type("Access-Control-Allow-Methods: POST") 
     ->set_content_type("Access-Control-Allow-Headers: Origin, Methods, Content-Type")
