嘿，我正在竭尽全力将此可运行的CURL脚本转换为Java：
@ECHO off
set COOKIES=.\cookies.txt
set USER=myUN
set PASSWORD="myPW"
set HOST=https://zzzzzzz.zzzzz.zz.zz:9443
cls
ECHO "Get the session cookie-------------------------------------"
set out1 = curl -k -c %cookies% "%host%/qm/authenticated/identity" > nul
ECHO "-----------------------------------------------------------"
ECHO "Use the session cookie to logon----------------------------"
curl -k -L -b %COOKIES% -c %COOKIES% -d j_username=%USER% -d j_password=%PASSWORD% %host%/qm/authenticated/j_security_check > nul
ECHO "-----------------------------------------------------------"
ECHO "Use the cookie to get the catalog--------------------------"
curl -k -L -b %COOKIES% -H "Accept: application/xml" %host%/qm/process/project-areas/_zzzzzzzzzzzzzzzzzzzz/members
ECHO "-----------------------------------------------------------"
其中：
-k: Allow insecure server connections when using SSL
-c <filename>: Write cookies to <filename> after operation
-L: Follow redirects
-b <data>: Send cookies from string/file
-H <header/@file>: Pass custom header(s) to server
-d <data>: HTTP POST data
我搜索了包括创建cookie的示例的Java代码，但是我还没有找到对上述代码有帮助的内容。
我能找到和修改POST调用的最近的是这个：
CookieStore cookieStore = new BasicCookieStore();
String USER = "myUN";
String PASSWORD = "myPW";
String HOST = "https://zzzzzzz.zzzzz.zz.zz:9443";
// CookieSpecs.STANDARD is the RFC 6265 compliant policy
RequestConfig requestConfig = RequestConfig
.custom()
.setCookieSpec(CookieSpecs.STANDARD)
.build();
// automatically follow redirects
CloseableHttpClient client = HttpClients
.custom()
.setRedirectStrategy(new LaxRedirectStrategy())
.setDefaultRequestConfig(requestConfig)
.setDefaultCookieStore(cookieStore)
.build();
HttpPost postIT = new HttpPost(HOST + "/qm/authenticated/identity");
List<NameValuePair> urlParams = new ArrayList<>();
urlParams.add(new BasicNameValuePair("j_username", USER));
urlParams.add(new BasicNameValuePair("j_password", PASSWORD));
postIT.setEntity(new UrlEncodedFormEntity(urlParams));
HttpResponse mmmCookie = client.execute(postIT);
// ... we have our cookie!
对于postIT，值为：
POSThttps://zzzzz.zzz.zzzz.zzzz:9443/qm/authenticated/identityHTTP / 1.1
但是，它的错误是：
错误：空
不知道为什么错误是null，因为postIT有数据吗？所以我不仅不能运行修改过的代码，而且仍然想知道如何使用cookie调用GET命令，即使上面的代码可行。
因此，简而言之：
帮助会很棒！
由于我们不知道是什么原因导致了您的密码错误，我建议您放弃第三方库，并使用java.net软件包：
public void readMembers(String schemeAndAuthority,
String username,
String password,
Path membersFileToWrite)
throws IOException {
URI baseURI = URI.create(schemeAndAuthority);
CookieHandler oldCookieHandler = CookieHandler.getDefault();
boolean oldFollowRedirects = HttpURLConnection.getFollowRedirects();
CookieHandler.setDefault(new CookieManager());
HttpURLConnection.setFollowRedirects(true);
try {
HttpURLConnection connection;
URI authURI = baseURI.resolve("/qm/authenticated/identity");
connection = (HttpURLConnection) authURI.toURL().openConnection();
connection.getResponseCode();
URI securityURI = baseURI.resolve(
"/qm/authenticated/j_security_check");
String postData =
"j_username=" + URLEncoder.encode(username, "UTF-8") + "&" +
"j_password=" + URLEncoder.encode(password, "UTF-8");
connection = (HttpURLConnection)
securityURI.toURL().openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
try (OutputStream postBody = connection.getOutputStream()) {
postBody.write(postData.getBytes(StandardCharsets.UTF_8));
}
connection.getResponseCode();
URI catalogURI = baseURI.resolve(
"/qm/process/project-areas/_zzzzzzzzzzzzzzzzzzzz/members");
connection = (HttpURLConnection)
catalogURI.toURL().openConnection();
connection.setRequestProperty("Accept", "application/xml");
try (InputStream responseBody = connection.getInputStream()) {
Files.copy(responseBody, membersFileToWrite);
}
} finally {
CookieHandler.setDefault(oldCookieHandler);
HttpURLConnection.setFollowRedirects(oldFollowRedirects);
}
}
但是，以上代码不能提供curl的-k选项。为此，我们必须创建一个自定义SSLContext，并使用允许所有证书的TrustManager进行初始化：
static class PermissiveTrustManager
extends X509ExtendedTrustManager {
private final X509ExtendedTrustManager[] realTrustManagers;
private interface Checker {
void checkWith(X509ExtendedTrustManager realTrustManager)
throws CertificateException;
}
PermissiveTrustManager() {
TrustManagerFactory factory;
try {
factory = TrustManagerFactory.getInstance(
TrustManagerFactory.getDefaultAlgorithm());
factory.init((KeyStore) null);
} catch (GeneralSecurityException e) {
// We should not be able to get here.
throw new RuntimeException(e);
}
TrustManager[] allTrustManagers = factory.getTrustManagers();
realTrustManagers = Arrays.stream(allTrustManagers)
.filter(tm -> tm instanceof X509ExtendedTrustManager)
.map(tm -> (X509ExtendedTrustManager) tm)
.toArray(X509ExtendedTrustManager[]::new);
}
private void check(Checker checker) {
try {
for (X509ExtendedTrustManager realTrustManager : realTrustManagers) {
checker.checkWith(realTrustManager);
}
} catch (CertificateException e) {
System.err.println("Ignoring invalid certificate");
e.printStackTrace();
}
}
private void check(Checker checker,
Socket socket) {
try {
for (X509ExtendedTrustManager realTrustManager : realTrustManagers) {
checker.checkWith(realTrustManager);
}
} catch (CertificateException e) {
System.err.println("Ignoring invalid certificate for " +
socket.getRemoteSocketAddress());
e.printStackTrace();
}
}
@Override
public void checkClientTrusted(X509Certificate[] certChain,
String authType,
Socket socket) {
check(tm -> tm.checkClientTrusted(certChain, authType, socket), socket);
}
@Override
public void checkClientTrusted(X509Certificate[] certChain,
String authType,
SSLEngine engine) {
check(tm -> tm.checkClientTrusted(certChain, authType, engine));
}
@Override
public void checkServerTrusted(X509Certificate[] certChain,
String authType,
Socket socket) {
check(tm -> tm.checkServerTrusted(certChain, authType, socket), socket);
}
@Override
public void checkServerTrusted(X509Certificate[] certChain,
String authType,
SSLEngine engine) {
check(tm -> tm.checkServerTrusted(certChain, authType, engine));
}
@Override
public void checkClientTrusted(X509Certificate[] certChain,
String authType) {
check(tm -> tm.checkClientTrusted(certChain, authType));
}
@Override
public void checkServerTrusted(X509Certificate[] certChain,
String authType) {
check(tm -> tm.checkServerTrusted(certChain, authType));
}
@Override
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}
}
private static SSLContext createPermissiveSSLContext()
throws IOException {
TrustManager[] trustManagers = { new PermissiveTrustManager() };
try {
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, trustManagers, null);
return context;
} catch (GeneralSecurityException e) {
throw new IOException(e);
}
}
public void readMembers(String schemeAndAuthority,
String username,
String password,
Path membersFileToWrite)
throws IOException {
URI baseURI = URI.create(schemeAndAuthority);
CookieHandler oldCookieHandler = CookieHandler.getDefault();
boolean oldFollowRedirects = HttpURLConnection.getFollowRedirects();
SSLContext oldSSLContext = null;
try {
oldSSLContext = SSLContext.getDefault();
} catch (GeneralSecurityException e) {
e.printStackTrace();
}
CookieHandler.setDefault(new CookieManager());
HttpURLConnection.setFollowRedirects(true);
SSLContext.setDefault(createPermissiveSSLContext());
try {
HttpURLConnection connection;
URI authURI = baseURI.resolve("/qm/authenticated/identity");
connection = (HttpURLConnection) authURI.toURL().openConnection();
connection.getResponseCode();
URI securityURI = baseURI.resolve(
"/qm/authenticated/j_security_check");
String postData =
"j_username=" + URLEncoder.encode(username, "UTF-8") + "&" +
"j_password=" + URLEncoder.encode(password, "UTF-8");
connection = (HttpURLConnection)
securityURI.toURL().openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
try (OutputStream postBody = connection.getOutputStream()) {
postBody.write(postData.getBytes(StandardCharsets.UTF_8));
}
connection.getResponseCode();
URI catalogURI = baseURI.resolve(
"/qm/process/project-areas/_zzzzzzzzzzzzzzzzzzzz/members");
connection = (HttpURLConnection)
catalogURI.toURL().openConnection();
connection.setRequestProperty("Accept", "application/xml");
try (InputStream responseBody = connection.getInputStream()) {
Files.copy(responseBody, membersFileToWrite);
}
} finally {
CookieHandler.setDefault(oldCookieHandler);
HttpURLConnection.setFollowRedirects(oldFollowRedirects);
if (oldSSLContext != null) {
SSLContext.setDefault(oldSSLContext);
}
}
}
显然，我没有办法对此进行测试。
