Javaouchdb4j DB连接

Question

I'm using couchdb4j to establish a connection with couchDB. It's working fine when im connecting to my local db, this is the code for that:

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

But i'm trying to get a connection with this site: stockquotetest.cloudant.com but it's not working, can anybody spot the problem?

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

i'm getting this error: INFO: basic authentication scheme selected

I also get this

when I run this line of code:

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

Answer 1

I reproduced this and ran into another issue before I got it working. First, the 6-parameter constructor for Session is what you're after:

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

In the example you gave above, this would work:

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

This is because if you don't set secure to true, the URL will not be constructed with https .

---

After that was working, the next error was the Database class assuming that update_seq is an int . Cloudant will return a String update_seq , not an integer. I altered the field, response parsing, and getter in the Database class from int to String to make the code work for me.

Answer 2

try this one ... make sure you are suing coucjdb4j lib for couchdb connection.

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

Database studentCouchDb = studentDbSession.getDatabase("database_name");

Hope this will help you.
