Java:使用HTTPBasic身份验证获取URL

问题描述 投票:9回答:4

我正在执行一些简单的HTTP身份验证,并得到一个

java.lang.IllegalArgumentException: Illegal character(s) in message header value: Basic OGU0ZTc5ODBk(...trimmed from 76 chars...)
(...more password data...)

我认为这是由于我的用户名和密码非常长,编码器用\n将其包装为76个字符。有什么办法可以解决这个问题?该网址仅支持HTTP基本身份验证。

这是我的代码:

private class UserPassAuthenticator extends Authenticator {
    String user;
    String pass;
    public UserPassAuthenticator(String user, String pass) {
        this.user = user;
        this.pass = pass;
    }

    // This method is called when a password-protected URL is accessed
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(user, pass.toCharArray());
    }
}

private String fetch(StoreAccount account, String path) throws IOException {
    Authenticator.setDefault(new UserPassAuthenticator(account.getCredentials().getLogin(), account.getCredentials().getPassword()));

    URL url = new URL("https", account.getStoreUrl().replace("http://", ""), path);
    System.out.println(url);

    URLConnection urlConn = url.openConnection();
    Object o = urlConn.getContent();
    if (!(o instanceof String)) 
        throw new IOException("Wrong Content-Type on " + url.toString());

    // Remove the authenticator back to the default
    Authenticator.setDefault(null);
    return (String) o;
}
java http authentication url http-authentication

这似乎是bug in Java

您是否尝试过使用其他HTTP客户端,例如Apache的库?

或者不是使用身份验证器,而是手动设置标题?

URL url = new URL("http://www.example.com/");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestProperty("Authorization", "Basic OGU0ZTc5ODBkABcde....");

令牌值是encodeBase64(“ username:password”)。

这对我有用。

HttpsURLConnection con = null;con =(HttpsURLConnection)obj.openConnection();字符串编码= Base64.getEncoder()。encodeToString(“ username:password” .getBytes(StandardCharsets.UTF_8));con.setRequestProperty(“ Authorization”,“ Basic” + encoding.replaceAll(“ \ n”,“”));

[我发现非法字符是由“授权:基本”引起的,已编码其中应为“授权”,“基本” +编码

从“授权:基本”更改为“授权”,“基本” +编码解决了标题问题中的非法字符。
