我正在使用 HP-ALM 12.01，它似乎充满了问题。我目前无法更新到另一个版本。

我正在尝试访问其余 api 以从 JUnit 自动上传测试结果。我正在使用此处显示的基础架构 （示例应用程序 -> 基础架构）。从中，我的连接脚本将 base64 编码的登录信息传递给身份验证点/身份验证，并且我正在检索有效的 LWSSO cookie。但是，当我使用此 cookie 连接到 rest/site-session 以接收我的 QCSession cookie 时，我收到 411 Length Required 错误。我试图将 Content-Length 硬编码到标题中，如此处所示

public void GetQCSession(){
    String qcsessionurl = con.buildUrl("rest/site-session");
    Map<String, String> requestHeaders = new HashMap<String, String>();
    requestHeaders.put("Content-Type", "application/xml");
    requestHeaders.put("Accept", "application/xml");
    requestHeaders.put("Content-Length", "0");
    try {
        Response resp = con.httpPost(qcsessionurl, null, requestHeaders);
        con.updateCookies(resp);
        System.out.println(resp.getStatusCode());
    } catch (Exception e) {
        e.printStackTrace();
    }
}

这没有用。我还尝试修改基础结构以自动注入 Content-Length 标头，如下所示

    private void prepareHttpRequest(
        HttpURLConnection con,
        Map<String, String> headers,
        byte[] bytes,
        String cookieString) throws IOException {

    String contentType = null;

    //attach cookie information if such exists
    if ((cookieString != null) && !cookieString.isEmpty()) {

        con.setRequestProperty("Cookie", cookieString);
    }

    //send data from headers
    if (headers != null) {

        //Skip the content-type header - should only be sent
        //if you actually have any content to send. see below.
        contentType = headers.remove("Content-Type");

        Iterator<Entry<String, String>>
                headersIterator = headers.entrySet().iterator();
        while (headersIterator.hasNext()) {
            Entry<String, String> header = headersIterator.next();
            con.setRequestProperty(header.getKey(), header.getValue());
        }
    }

    // If there's data to attach to the request, it's handled here.
    // Note that if data exists, we take into account previously removed
    // content-type.
    if ((bytes != null) && (bytes.length > 0)) {

        con.setDoOutput(true);

        //warning: if you add content-type header then you MUST send
        // information or receive error.
        //so only do so if you're writing information...
        if (contentType != null) {
            con.setRequestProperty("Content-Type", contentType);
        }

        OutputStream out = con.getOutputStream();
        out.write(bytes);
        out.flush();
        out.close();
        con.setRequestProperty("Content-Length", Integer.toString(bytes.length));
    } else {
        con.setRequestProperty("Content-Length", "0");
    }
}

这也不起作用。请注意， setRequestProperty 只是对MessageHeader执行 .set(key, value)

有没有人处理过这个问题或知道如何解决它？

请注意，邮递员不会出现这些问题。所有 4 个 cookie 都是在站点会话发布后生成的。

Barney 的代码示例被略微扩展，因为它不适合 ALM 12.5 设置。主要区别是，有更多的 cookie 和 cookie 附加到标题

  Config config = new Config(dataService);
  String almURL = "https://" + config.host() + "/qcbin";

  client = ClientBuilder.newBuilder().build();
  target = client.target(almURL).path("api/authentication/sign-in");
  invocationBuilder = target
        .request(new String[] {"application/xml"})
        .accept(new String[] {"application/xml"});
  invocationBuilder.header("Authorization", getEncodedAuthString(config.username(), config.password()));

  res = invocationBuilder.post(null);

  String qcsessioncookie = res.getCookies().get("QCSession").getValue();
  String almusercookie = res.getCookies().get("ALM_USER").getValue();
  String xsrftokencookie = res.getCookies().get("XSRF-TOKEN").getValue();
  String lswoocookie = res.getCookies().get("LWSSO_COOKIE_KEY").getValue();

  /* Get the test-Set Data defect */
  String midPoint = "rest/domains/" + config.domain() + "/projects/" + config.project();
  target = client.target(almURL).path(midPoint).path("test-sets/1");
  invocationBuilder = target
        .request(new String[] {"application/xml"})
        .accept(new String[] {"application/xml"});

  concatenatedHeaderCookieString = "QCSession=" + qcsessioncookie + ";" + "ALM_USER=" + ";" + almusercookie + ";" + "XSRF-TOKEN=" + xsrftokencookie + ";"
        + "LWSSO_COOKIE_KEY=" + lswoocookie;
  invocationBuilder.header("Cookie", concatenatedHeaderCookieString);

  res = invocationBuilder.get();

问题是 Java 的 HttpURLConnection 在手动设置时会忽略某些属性。其中之一是内容长度。这是因为它会自动设置它自己。但是，如果您不发送任何数据，则它根本不会发送它，由于其过时的 http 协议，ALM 不接受该数据，因为它期望接收 0 的 Content-Length。

要解决此问题，您必须告诉 java 允许限制标头。这是通过运行 

System.setProperty("sun.net.http.allowRestrictedHeaders", "true");

有关更多信息，请查看此处为什么 Content-Length HTTP 标头字段使用的值与 Java 代码中给出的值不同？
