Javaouchdb4j DB连接

Question

我正在使用沙发床4j与沙发床建立连接。 即时通讯连接到我的本地数据库时工作正常，这是该代码：

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

但是我正在尝试与以下网站建立联系：stockquotetest.cloudant.com，但该网站无法正常工作，有人可以发现问题吗？

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

我收到此错误：信息：选择基本身份验证方案

我也得到这个

当我运行以下代码行时：

        Session NewSession = new Session("https://user:pass@stockquotetest.cloudant.com/", 80, true);

Answer 1

我转载了此内容，并在工作之前遇到了另一个问题。 首先，您需要使用Session的6参数构造函数 ：

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，如果未将secure设置为true， 则不会使用https构造URL 。

在工作之后，下一个错误是Database类， 假设update_seq是一个int 。 Cloudant将返回字符串update_seq ，而不是整数。 我将Database类中的字段，响应解析和getter从int更改为String以使代码对我有用。

Answer 2

尝试这个...确保您使用coucjdb4j lib进行ouchdb连接。

会话studentDbSession = new Session（“ localhost”，5984）;

数据库studentCouchDb = studentDbSession.getDatabase（“ database_name”）;

希望这会帮助你。
