Java |存储来自 URL 的图像 | java.io.IOException：URL 403

Question

其他图像有效，但显然不是这个。

https://www.kingjamesbibleonline.org/Inspirational-Images/large/Isaiah_55-6.jpg

代码：

public static void imageFromURL(URL url, String saveAs) throws IOException {
    HttpURLConnection httpURLCon = (HttpURLConnection) url.openConnection();
    httpURLCon.addRequestProperty("User-Agent", "Mozilla/4.76");
    BufferedImage c = ImageIO.read(url.openStream());
    File outputFile = new File("C:.../resources/" + saveAs);
    ImageIO.write(c, "jpg", outputFile);
}

错误信息：

java.io.IOException: Server returned HTTP response code: 403 for URL: https://www.kingjamesbibleonline.org/Inspirational-Images/large/Isaiah_55-6.jpg
    at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1840)
    at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1441)
    at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:254)
    at java.net.URL.openStream(URL.java:1045)
    at MainActivity.imageFromURL(MainActivity.java:41)
    at MainActivity.main(MainActivity.java:49)

尝试过其他解决方案，例如：

HttpURLConnection httpcon = (HttpURLConnection) url.openConnection(); 
httpcon.addRequestProperty("User-Agent", "Mozilla/4.76");

uc = url.openConnection();
uc.addRequestProperty("User-Agent", 
"Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)");

URLConnection conn = url.openConnection();
conn.setRequestProperty("User-Agent", "Mozilla/5.0");

您已经打开了与图像 URL 的连接并将其存储在 httpURLCon 中。

重新使用该连接，因为这是您为其设置了用户代理的连接：

HttpURLConnection httpURLCon = (HttpURLConnection) url.openConnection();
httpURLCon.addRequestProperty("User-Agent", "Mozilla/4.76");
BufferedImage c = ImageIO.read(httpURLCon.getInputStream());
