[zaheer.agadi]

Hi

I have a following class that is written Java and makes use of apache
http client library,I am new to python can any one suggest me a python
equivalent of this following class,

Thanks ,

public class Authenticate{

private String storageUserName=null;
private String storagePassword=null;
private String authorization=null;
private String identityHostName = null;
private String identityPortNumber = null;

private String accessKey=null;
private String secretKey=null;

public String getStoragePassword() {
return storagePassword;
}

public void setStoragePassword(String storagePassword) {
this.storagePassword = storagePassword;
}

public String getStorageUserName() {
return storageUserName;
}

public void setStorageUserName(String storageUserName) {
this.storageUserName = storageUserName;
}

public String getIdentityHostName() {
return identityHostName;
}

public void setIdentityHostName(String identityHostName) {
this.identityHostName = identityHostName;
}

public String getIdentityPortNumber() {
return identityPortNumber;
}

public void setIdentityPortNumber(String identityPortNumber) {
this.identityPortNumber = identityPortNumber;
}

public String getAccessKey() {
return accessKey;
}

public void setAccessKey(String accessKey) {
this.accessKey = accessKey;
}

public String getSecretKey() {
return secretKey;
}

public void setSecretKey(String secretKey) {
this.secretKey = secretKey;
}

Hi,

This looks like a perfect job for httplib and urllib2 modules.

Hi,

Thanks Alex,

Can you provide me more details on httplib and urllib ?

The details can be found in Python documentation (http://python.org/doc),
on these pages:
http://docs.python.org/library/httplib.html

I'm sure you can figure out the location of the documentation for the urllib2
module. Documentation includes examples too.


Regards,
alex.
