サーバーに画像をアップロードします。サーバーにアップロード中に502エラーが表示されます。以下は、私がtext/htmlのを示すエラーのContent-Typeで サーバーに画像をアップロード中にエラーが発生しました
{ status code: 502, headers {
Connection = "keep-alive";
"Content-Length" = 181;
"Content-Type" = "text/html";
Date = "Mon, 09 Oct 2017 10:47:49 GMT";
Server = "nginx/1.4.6 (Ubuntu)";
} }
Content-Typeの境界を削除した場合、私のサーバは105エラーをスローします。バックエンドの開発者は、content-typeが一致しないと言っています。
