java - 不支持 HTTP 版本 :505

Question

我编写了 selenium/Java 脚本来查找网站上损坏的图像。在 34 个图像中，有 2 个图像抛出 505 错误代码(不支持 HTTP 版本)。

这是我的代码

    HttpURLConnection huc = null;
    int respCode = 200;
    huc = (HttpURLConnection) (new URL(url).openConnection());
    huc.setRequestMethod("HEAD");

    huc.setConnectTimeout(2000);
    huc.connect();
    respCode = huc.getResponseCode();

    if (respCode >= 400) {
        System.out.println(url + " is a broken with error code:" + respCode);
    } else {
        System.out.println(url + " is a good");
    }

505 Errors:

Answer 1

问题出在 URL 上，它包含空格。您可以使用 Java URL 编码器作为通用解决方案:Java URL encoding of query string parameters

在您的情况下，只需替换 %20 中的空格，如下所示:

        String url = "https://s7d4.scene7.com/is/image/DuPontCorteva/IMG-Soja-CampoDeSojaConFocoYDesenfoque-0_71-1%20Desktop(new)?$callToActionCard_tablet$";
    HttpURLConnection huc = null;
    int respCode = 200;
    huc = (HttpURLConnection) (new URL(url).openConnection());
    huc.setRequestMethod("HEAD");

    huc.setConnectTimeout(2000);
    huc.connect();
    respCode = huc.getResponseCode();

    if (respCode >= 400) {
        System.out.println(url + " is a broken with error code:" + respCode);
    } else {
        System.out.println(url + " is a good");
    }

输出:
