HttpClient 4.2.2 및 사용자 이름/암호가있는 프록시에 문제가 있습니다. 이 방식으로 작동 HttpClient를 :HttpClient 4.2.2 및 사용자 이름/암호가있는 프록시
- 프록시 물건이없는
- 보내기 요청이
- 407 오류 프록시와
- 보내기 요청과 오징어에서 응답을 받기 (그러나 나는 각 요청에 대한 프록시 매개 변수를 설정) 목록 항목 물건
매우 이상한 행동입니다. 각 요청에 프록시에 대한 정보를 추가 할 수 있습니까? 나는 각 요청에 하드 코딩 된 "Proxy-Authorization"헤더를 추가하려고 시도했으며 HttpClient가 동일한 작업을 수행 할 수없는 이유는 무엇입니까?
자바 하드 헤더와 코드
DefaultHttpClient httpClient = new DefaultHttpClient();
httpClient.getParams().setParameter(PROTOCOL_VERSION, HTTP_1_1);

String proxyServer = getProxyServer();
int proxyPort = getProxyPort();
List<String> authpref = new ArrayList<String>();
authpref.add(AuthPolicy.BASIC);
httpClient.getParams().setParameter(AuthPNames.PROXY_AUTH_PREF, authpref);
String proxyUser = getProxyUser();
String proxyPassword = getProxyPassword();
CredentialsProvider credsProvider = httpClient.getCredentialsProvider();
credsProvider.setCredentials(new AuthScope(proxyServer, proxyPort), new UsernamePasswordCredentials(proxyUser, proxyPassword));
httpClient.setCredentialsProvider(credsProvider);
HttpHost proxy = new HttpHost(proxyServer, proxyPort, (proxyServer.indexOf("https") != 0) ? "http" : "https");
httpClient.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy);

getProxyServer은() – Lazy
재미있는 ...이 IP 주소를 반환 당신은 http/https 점검없이 HttpHost를 시도 했습니까? 그게 어떤 영향을 미칠지 궁금하네요. 그건 제쳐두고, 내가 구성되어있는 프록시를 사용하려고 시도하는 경우에도 디버거를 사용하여 추적하려고합니다. –
예, http/https없이 시도했지만 결과는 같습니다. – Lazy
