我正在使用 couchdb4j 与 couchDB 建立连接。当我连接到我的本地数据库时它工作正常，这是代码：

Session LocalSession= new Session("localhost", 5984);

但我正在尝试与这个网站建立联系：stockquotetest.cloudant.com 但它不起作用，有人能发现问题吗？

Session NewSession = new Session("stockquotetest.cloudant.com/", 5984, "user", "pass");

我收到此错误：信息：已选择基本身份验证方案

我也得到这个

我复制了这个并在我开始工作之前遇到了另一个问题。首先，6参数构造函数Session是你所追求的：

public Session(String host, int port, String user, String pass, boolean usesAuth, boolean secure) {

在您上面给出的示例中，这将起作用：

new Session("stockquotetest.cloudant.com", 443, "user", "pass", true, true);

这是因为如果您不设置secure为 true，则不会使用 https 构造 URL。

在那之后，下一个错误是假设它是 intDatabase的类。Cloudant 将返回一个 String ，而不是一个整数。我将类中的字段、响应解析和 getter从更改为 以使代码适合我。update_sequpdate_seqDatabaseintString

试试这个......确保你正在起诉 coucjdb4j lib 进行 couchdb 连接。

会话 studentDbSession = new Session("localhost", 5984);

数据库 studentCouchDb = studentDbSession.getDatabase("database_name");

希望这会帮助你。
