放入和删除数据错误err_spdy_protocol_error

Question

我试图通过fetch从Web服务中删除和删除数据，但是我收到以下错误

净:: ERR_SPDY_PROTOCOL_ERROR

const Headers = { 'Content-Type': 'application/json', 'Access-Control-Request-Method': '*'};

const url =＆＃39; https://tesisweb.000webhostapp.com/genTesis/api/public/coo/1＆＃39;;

const req = new Request(serverUrl + url, {method: 'PUT', headers: Headers, body: obj});

return fetch(req)
    .then(status)
    .then((response) => {

        return response.json();

    });

在BackEnd我使用php slim和eloquent

Middelware

    $corsOptions = array(
"origin" => "*",
"exposeHeaders" => array("Content-Type", "X-Requested-With", "X-authentication", "X-client"),
"allowMethods" => array('GET', 'POST', 'PUT', 'DELETE', 'OPTIONS')

）; $ cors = new \ CorsSlim \ CorsSlim（$ corsOptions）;

$ APP-＆gt;添加（$ CORS）;
