现在,我遇到了CORS(跨域资源共享)问题,尤其是在尝试向瘦API发送授权时.我试图删除jquery上的授权标头,它的工作原理就像一个魅力！但是我需要通过api密钥的授权,我不知道如何绕过预检模式(OPTIONS).这是JavaScript代码.

$.ajax({
    type:'GET',
    url:baseApi+'/code/account',
    crossDomain:true,
    xhrFields:{
        withCredentials:true
    },
    beforeSend:function(xhr){
        $overlay.css('display','block');
        xhr.setRequestHeader("Authorization",boot._header);
    },
    complete:function(xhr){
        // complete scope        
    }
});

在苗条的框架上,我将白名单来源域(www.example.com)设置为Access-Control-Allow-Origin.这是完整的配置

if (isset($_SERVER['HTTP_ORIGIN'])) {
    if($_SERVER['HTTP_ORIGIN'] == "http://www.example.com"){
        header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
    }
    header('Access-Control-Allow-Credentials: true');
    header('Access-Control-Max-Age: 86400');    // cache for 1 day
}

if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_METHOD']))
        header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");

    if (isset($_SERVER['HTTP_ACCESS_CONTROL_REQUEST_HEADERS']))
        header("Access-Control-Allow-Headers: Authorization, authorization, Content-Type");
}

这是完整的请求和响应头

响应标题

我尝试了其他人的可能解决方案,但没有机会解决此问题.始终显示404,其中包含调用的OPTIONS方法,而不是应有的GET方法.

解决方法:

经过研究和调查,我最终按照@Mika Tuupola的建议,将CORS中间件用于Slim.但是由于我使用的是Slim v2,因此此回购https://github.com/palanik/CorsSlim适合我.如果您使用的是Slim v3,请使用由我们的救助者创建的此回购https://github.com/tuupola/cors-middleware.希望能帮助到你！
