我有一些工作的java代码执行以下操作:
URL myUrl = new URL("http://localhost:8080/webservice?user=" + username + "&password=" + password + "&request=x");
HttpURLConnection myConnection = (HttpURLConnection) myUrl.openConnection();
myConnection.setRequestMethod("POST");
// code continues to read the response stream
但是,我注意到我的网络服务器访问日志包含所有连接用户的明文密码。我想从访问日志中获取此信息,但网络服务器管理员声称需要在我的代码中更改,而不是通过webserver配置。
我尝试将代码更改为以下内容:
URL myUrl = new URL("http://localhost:8080/webservice");
HttpURLConnection myConnection = (HttpURLConnection) myUrl.openConnection();
myConnection.setRequestMethod("POST");
// start of new code
myConnection.setDoOutput(true);
myConnection.addRequestProperty("username", username);
myConnection.addRequestProperty("password", password);
myConnection.addRequestProperty("request", "x");
// code continues to read the response stream
现在访问日志不包含用户名/密码/请求方法。但是,Web服务现在抛出一个异常,表明它没有收到任何用户名/密码。
我的客户端代码出错了什么?我也尝试使用“setRequestProperty”而不是“addRequestProperty”,它也有相同的破坏行为。
答案 0 :(得分:7)
我实际上在another question on stackoverflow.
中找到了答案正确的代码应该是:
URL myUrl = new URL("http://localhost:8080/webservice");
HttpURLConnection myConnection = (HttpURLConnection) myUrl.openConnection();
myConnection.setRequestMethod("POST");
myConnection.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(myConnection.getOutputStream ());
wr.writeBytes("username=" + username + "&password="+password + "&request=x");
// code continues to read the response stream
