通过身份验证将Java post xml文件发送到url

我目前使用下面的Linux Shell脚本

shell_exec("wget --output-document=/var/www/html/kannel/rresults/".$file.".res --post-file=/var/www/html/kannel/rbilling/".$file." --http-user=user1 --http-password=pass1 --header=\"Content-Type: text/xml\" 77.203.65.164:6011");

此shell脚本使用linux中的

wget

执行带有基本身份验证的url，并上载文件

我想将其转换为java，以便：

连接

鉴定

Post XML文件

另外，是否可以进行一次身份验证，然后发布任意数量的文件

更新。。。。。。。。。。。。。。。。。。。。 我试过下面的代码

我尝试了上面的代码，但出现了错误：

验证字符串：optiweb:optiweb
Base64编码的身份验证字符串：b3B0aXdlYjpvcHRpd2Vi
线程“main”java.io.IOException中的异常：服务器返回了URL:77.203.65.164:6011的HTTP响应代码：500
位于sun.net.www.protocol.http.HttpURLConnection.getInputStream（HttpURLConnection.java:1403）
位于URLUploader.main（URLUploader.java:32）

有什么问题吗？

您可以使用它

您需要在请求中提供正确的http基本身份验证头。在Java中，您可以通过对username:password进行编码并将其与请求一起传递：

URL url = new URL(urlString);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
conn.setRequestProperty ("Authorization", Base64.encode(username+":"+password));

OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());

writer.write(data);
writer.flush();
String line;
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
while ((line = reader.readLine()) != null) {
  System.out.println(line);
}
writer.close();
reader.close();

其中“数据”包含要发布到服务器的内容

您是强调一次身份验证，还是每次都进行身份验证就可以了？我希望它进行一次身份验证，然后进行多个帖子和响应。它也可以是http摘要身份验证，因此您的答案仅适用于http基本身份验证

wget

支持两种身份验证方法。您好，所以我可以使用这个：writer.write（“/var/www/html/newfile.xml”）？这行得通吗？不，那只是发布字符串“/var/www/html/newfile.xml”。您需要做的是（通过FileInputReader或类似的东西）读入文件并将其发布到字节数组中并使用它？我知道我听起来很懒，但是你能帮我把这部分添加到你的代码样本中吗？
