Question

我正在尝试使用java将数据发布到此URL：

https:www.stackoverflow.com

它没有更新数据。

但是当我尝试使用curl时，它正在用这个url更新数据：

E:\curl ssl>curl -k -X POST -u"user:pass" "www.stackoverflow.com"

修改

public void authenticatePostUrl() {

        HostnameVerifier hv = new HostnameVerifier() {

            @Override
            public boolean verify(String urlHostName, SSLSession session) {
                System.out.println("Warning: URL Host: " + urlHostName
                        + " vs. " + session.getPeerHost());
                return true;
            }
        };
        // Now you are telling the JRE to trust any https server.
        // If you know the URL that you are connecting to then this should
        // not be a problem
        try {
            trustAllHttpsCertificates();
        } catch (Exception e) {
            System.out.println("Trustall" + e.getStackTrace());
        }
        HttpsURLConnection.setDefaultHostnameVerifier(hv);
        StringWriter sw = new StringWriter();
        PrintWriter pw = new PrintWriter(sw);
        try {
            URL url = new URL("www.stackoverflow.com");

            String credentials = "user" + ":" + "password";
            String encoding = Base64Converter.encode(credentials.getBytes("UTF-8"));

                pw.println(line);
            }
        } catch (MalformedURLException e) {
            e.printStackTrace();
            pw.println("Invalid URL");
        } catch (IOException e) {

    // Just add these two functions in your program

        // Create a trust manager that does not validate certificate chains:

        javax.net.ssl.TrustManager[] trustAllCerts =

        new javax.net.ssl.TrustManager[1];

        javax.net.ssl.TrustManager tm = new TempTrustedManager();

        trustAllCerts[0] = tm;

        javax.net.ssl.SSLContext sc =

        javax.net.ssl.SSLContext.getInstance("SSL");

        sc.init(null, trustAllCerts, null);

        javax.net.ssl.HttpsURLConnection.setDefaultSSLSocketFactory(

        sc.getSocketFactory());

    }

为什么它不能用Java？

Answer 1

所以你试图将do_not_disturb=no发送到服务器？这就是为什么我在评论中问你previous question ......

通过将?do_not_disturb=No附加到URL，这些参数会自动作为GET请求发送到服务器，要将它们作为POST发送，您必须将它们放在请求正文中，如下所示：

String postData = "do_not_disturb=No";

OutputStreamWriter outputWriter = new OutputStreamWriter(uc.getOutputStream());
outputWriter.write(postData);
outputWriter.flush();
outputWriter.close();

然后你的Accept - 标题可能是错误的，因为它告诉服务器你期望获得某些响应数据的格式（content）。如果您希望从服务器获取一些XML，请阅读uc.setRequestProperty("Accept", "application/xml");。

<强>更新

通过将verbose-flag（-v）添加到curl命令，我得到了它发送的标题：

POST /api/domains/amj.nms.mixnetworks.net/subscribers/9001/ HTTP/1.1
Authorization: Basic {URL_ENCODED_AUTHENTICATION_STRING}
User-Agent: curl/7.22.0 (i686-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/1.2.3.4 libidn/1.23 librtmp/2.3
Host: 8.7.177.4
Accept: */*
Content-Length: 17
Content-Type: application/x-www-form-urlencoded

所以请尝试更改您的代码：

uc.setRequestProperty("Authorization", String.format("Basic %s", encoding));
uc.setRequestMethod("POST");
uc.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=utf-8");
uc.setRequestProperty("Accept", "*/*");
uc.setRequestProperty("Content-Length", Integer.toString(postData.getBytes().length));

用户代理字符串应该没有意义，除非你的服务器做了很奇怪的事情。

如果它仍然不起作用，请查看变量encoding是否与详细卷曲运行中Basic之后的部分具有相同的值。

Answer 2

在我的情况下，curl适用于POST调用，java中的HttpUrlConnection将不起作用，返回403禁止说我正在使用匿名登录，但该POST调用应该完成的实际工作已经完成。起初非常令人困惑。然后发现我需要禁用url重定向（这是xtend代码，但您知道了）：

val conn = url.openConnection() as HttpURLConnection
conn.setInstanceFollowRedirects(false)

Answer 3

这里有一些选择。一个是你可以使用Runtime（）。exec。

添加一个Java类来运行bash脚本

但是，我调试了我的Java连接，发现我没有使用TLSv1.2

        System.setProperty("deployment.security.TLSv1.2", "true");
        System.setProperty("https.protocols", "TLSv1.2");
        System.setProperty("javax.net.debug", "ssl"); // "" or "ssl"

从Java 7迁移到Java 8后，Java命令工作。

curl经常工作但是Java没有工作，Java工作和卷曲不工作。我通常检查SSL配置（使用-v和-k表示curl），尝试更改http与https或在此处查看SSL证书安装程序：https://confluence.atlassian.com/download/attachments/180292346/InstallCert.java（我修改了此项以在运行时安装证书）

https URL与curl一起工作正常，但不适用于Java
