本文介绍了使用CloudantClient Java API的Cloudant DB的HttpHostConnectException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用CloudantClient库连接到Cloudant CouchDB。此调用不会引发任何异常。但是在此之后，当我使用CloudantClient进行任何呼叫时，都会收到 HttpHostConnectException 。我试过拨打 serverVersion ， getAllDbs 等电话。这是代码：
I am using the CloudantClient libary to connect to Cloudant CouchDB. There are no exceptions thrown by this call. But after this, when I am making any call using CloudantClient, I am getting HttpHostConnectException. I tried making calls like serverVersion, getAllDbs, etc. Here is the code:
cloudantClient = new CloudantClient(username, password);
//ConnectOptions options = new ConnectOptions();
//options.setProxyHost("myproxy.address.co.in");
//options.setProxyPort(8080);
//options.setConnectionTimeout(3000);
//options.setMaxConnections(100);
//options.setSocketTimeout(30000);
//cloudantClient = new CloudantClient(username, password, options);
//cloudantClient = new CloudantClient(username, password);
//cloudantClient = new CloudantClient(username, username, password);
//cloudantClient = new CloudantClient(url, username, password);
System.out.println("Connected to Cloudant");
System.out.println("Trying to fetch metadata from Cloudant");
System.out.println("Server Version: " + cloudantClient.serverVersion());
List<String> databases = cloudantClient.getAllDbs();
System.out.println("All my databases : ");
for ( String db : databases ) {
System.out.println(db);
}
我正在Eclipse中运行此代码，并且凭据是正确的，我可以从浏览器其余客户端成功调用。完整的异常堆栈跟踪（出于安全原因，我已用acct字符串替换了日志中的acct / pwd）：
I am running this code in Eclipse and the credentials are correct, as I can call successfully from browser rest client. Complete stack trace for the exception (I have replaced the acct/pwd in the log with acct string for security reasons):

在异常跟踪中我看到的是某些IP地址被附加到URL：< Account> .cloudant.com / 184.173.103.226
What I can see in the exception trace is some IP address is getting appended to the URL: <Account>.cloudant.com/184.173.103.226
我不确定如何以及何时将该IP添加到URL中。我直接使用Java Cloudant Client API。
I am not sure how and when this IP is getting added in the URL. I am directly using the Java Cloudant Client API's.
有人可以提供任何指针/输入来解决此问题吗？
Can anybody provide any pointers/inputs to resolve this issue?
在下面添加更新的代码以供参考我尝试连接的所有diff选项-
Adding the updated code below for reference about all diff options i tried for connection -
在下面的ConnectOptions中设置了proxy时添加堆栈跟踪。我已经用安全性字符串替换了真实帐户凭证和代理详细信息。 -

推荐答案
原来，设置代理服务器时HTTP的问题是我们的错误（对此感到抱歉）。我们发布了具有此问题的修复程序的1.2.1。
It turned out the issue with HTTP when setting a proxy was a bug at our end (sorry about that). We released 1.2.1 with the fix for this problem.
这篇关于使用CloudantClient Java API的Cloudant DB的HttpHostConnectException的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
