[英]apache httpclient + ntlm Authentication
我有一個客戶端通過https帖子將文件上傳到服務器。 它使用代理,這是我的代碼
public void upload() throws Exception {
//create default client
DefaultHttpClient client = new DefaultHttpClient();
//set proxy authentication if specified
if (proxy.equals("yes") && proxyAuth.equals("yes")){
client.getCredentialsProvider().setCredentials(
new AuthScope(address, port),
new UsernamePasswordCredentials(proxyUsername, proxyPassword));
}
//set proxy if specified
if (proxy.equals("yes")){
HttpHost proxy = new HttpHost(address, port);
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY,proxy);
}
HttpPost post = new HttpPost(url);
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
File dir = new File(inputFilePath);
File[] fileArray = dir.listFiles();
File file = fileArray[0];
FileBody uploadFilePart = new FileBody(file);
entity.addPart("file", uploadFilePart);
entity.addPart("username", new StringBody(username));
entity.addPart("password", new StringBody(password));
post.setEntity(entity);
//execute post and get response
String response = EntityUtils.toString(client.execute(post).getEntity(), "UTF-8");
client.getConnectionManager().shutdown();
log4j.info(response);
if(!response.substring(0, 3).equalsIgnoreCase("200")){
Exception e = new Exception("An error has occurred server side: ");
throw e;
}
}
現在問題是這有時完美有效,有時我得到以下錯誤。
org.apache.http.impl.client.AbstractAuthenticationHandler.selectScheme(AbstractAuthenticationHandler.java:149) - 不支持身份驗證方案ntlm“
您需要按照http://hc.apache.org/httpcomponents-client-ga/ntlm.html中的說明注冊NTLM處理程序:
client.getAuthSchemes().register("ntlm", new NTLMSchemeFactory());
嘗試 - 而不是這個:新的UsernamePasswordCredentials(proxyUsername,proxyPassword)
使用此:new NTCredentials(proxyUsername,proxyPassword,“localhostname”,“domain”)
