[英]server returns java.io.IOException: Server returned HTTP response code: 400 for URL
[英]java.io.IOException: Server returned HTTP response code: 400 for URL
我正在研究一個線程java應用程序,它打一個url來發送短信
問題是我在NTLM代理服務器后面,我已經搜索了大部分時間並嘗試了許多解決方案,但沒有成功應用程序給出標題錯誤,當我嘗試打印錯誤響應時,我發現它的錯誤頁面來自代理服務器
這是擊球代碼
System.setProperty("java.net.useSystemProxies", "true");
System.setProperty("http.proxyHost", AUTH_PROXY");
System.setProperty("http.proxyPort", AUTH_PROXY_PORT);
System.setProperty("http.proxyUser", AUTH_USER);
System.setProperty("http.proxyPassword", AUTH_PASSWORD);
Authenticator.setDefault(
new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(AUTH_USER, AUTH_PASSWORD.toCharArray());
}
}
);
URL url = new URL(urlString);
HttpURLConnection httpConn =(HttpURLConnection)url.openConnection();
httpConn.setReadTimeout(10000);
String resp = getResponse(httpConn);
logger.info("urlString=" + urlString);
logger.info("Response=" + resp);
在這里,我得到了respoonse
private String getResponse(HttpURLConnection Conn) throws IOException {
InputStream is;
if (Conn.getResponseCode() >= 400) {
is = Conn.getErrorStream();
} else {
is = Conn.getInputStream();
}
String response = "";
byte buff[] = new byte[512];
int b = 0;
while ((b = is.read(buff, 0, buff.length)) != -1) {
response += new String(buff, 0, b);
}
is.close();
return response;
}
任何幫助表示贊賞謝謝
經過多次嘗試后,我意識到上面的代碼很好,我得到的400錯誤來自於不編碼可能有空格的URL參數
剛用過
URLEncoder.encode(urlParameter,"UTF-8");
對於代碼有空格的參數解決了問題
