Question

我正在尝试从本地连接到cloudantDB。这是我从IBM示例中获得的代码，它正在使用已部署的在线版本。

   try {
        System.out.println("Connecting to Cloudant : " + user);

        //This works
        CloudantClient client = ClientBuilder.account(user)
                .username(user)
                .password(password)
                .connectTimeout(30, TimeUnit.SECONDS)
                .readTimeout(30, TimeUnit.SECONDS)
                .build();
        System.out.println("Connected to Cloudant : " + user);

        //This doesn't works and fire the errror Show the server version
        System.out.println("Server Version: " + client.serverVersion());

        //This doesn't works and fire the error to. Show databases
        System.out.println("Dbs: " + client.getAllDbs());

        return client;
    } catch (Exception e) {
        throw new RuntimeException("Unable to connect", e);
    }

从localhost我有这个错误：

我不是代理人...... 我做错了什么？

Answer 1

来自cloudant控制台＆＃34;生成api密钥＆＃34;我收到了帐号/密码和数据库名称

如果您使用的是API密钥，则帐户名称与用户名不同。在您的示例中，他们都使用user

进行调用

ClientBuilder.account(account_name) // needs to be the part before .cloudant.com .username(api_key_user) // needs to be the API key

其次，API密钥是按数据库进行的，因此无权执行getAllDbs()。

FWIW .build()实际上没有连接到Cloudant，它只构建一个CloudantClient对象，直到需要时才会发出HTTP请求。

Answer 2

解决。用户和密码必须从Cloudant服务创建 - ＆gt;服务信誉 - ＆gt;新证书。

我使用了从云端创建的错误凭证 - ＆gt;数据库 - ＆gt;权限 - ＆gt;生成API密钥。
