Question

我已经编写了Selenium / Java脚本来查找网站上的损坏图像。在34张图像中，有2张图像抛出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");
    }

Answer 1

问题与URL一起使用，它包含空格。您可以将Java URL编码器用于一般解决方案：Java URL encoding of query string parameters

对于您而言，只需按以下步骤替换％20中的空格：

        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：

https://s7d4.scene7.com/is/image/DuPontCorteva/IMG-Soja-CampoDeSojaConFocoYDesenfoque-0_71-1%20Desktop(new)?$callToActionCard_tablet$ is a good

Answer 2

鉴于您使用了Selenium和Java，应该将OkHttp库“免费”作为Selenium transitive dependencies的一部分。

因此，您可以将图像检查逻辑修改为：

OkHttpClient client = new OkHttpClient().newBuilder().build();
Request request = new Request.Builder().url(url).method("HEAD", null).build();
Response response = client.newCall(request).execute();
int respCode = response.code();

由于特殊的URL Encoding导致您当前的请求失败，OkHttp客户端会自动处理characters which are not allowed in URLs

您可能还想obtain browser cookies并将其添加到您的请求中，因为端点可能需要基于cookie的身份验证

不支援HTTP版本：505
