In a java class, am using an arraylist say reports containing list of all the reports which have reportid, reportname, reporttype etc which i want to add into NameValuePair and send a Http postmethod call to a particular url.
I want to add the arraylists - reportname into name value pair(org.apache.commons.httpclient.NameValuePair) and then use the http client post method to submit the name value pair data to a particular url.
Here is my name value pair
if (validateRequest()) {
NameValuePair[] data = {
new NameValuePair("first_name", firstName),
new NameValuePair("last_name", lastName),
new NameValuePair("email", mvrUser.getEmail()),
new NameValuePair("organization", mvrUser.getOrganization()),
new NameValuePair("phone", mvrUser.getPhone()),
new NameValuePair("website", mvrUser.getWebsite()),
new NameValuePair("city", mvrUser.getCity()),
new NameValuePair("state", mvrUser.getState()),
new NameValuePair("country", mvrUser.getCountry()),
new NameValuePair(**"report(s)", reports**.)
};
please suggest me how to add the reports arraylist reportname into reports field of NameValuePair.
-- thanks
@ adarsh can I use with generics something like this?
reportname = "";
for (GSReport report : reports) {
reportname = reportname + report.getReportName();
reportname += ",";
}
and then add in namevalue pair as
new NameValuePair("report(s)", reportname)
for name value pair use map like things... eg. Hastable(it is synchronized) , u can use other implementation of Map which are not synchronized.
I suggest to serialize your reports ArrayList
into a JSON formatted String
.
new NameValuePair("reports", reportsAsJson)
You can build your reportsAsJson variable using any of the JSON serialization libraries (like the one at http://json.org/java/ ). It will have approximatively this format :
reportsAsJson = "[{reportid:'1',reportname:'First Report',reporttype:'Type 1'}, {reportid:'2',reportname:'Seond Report',reporttype:'Type 2'}]";
Well, you cannot do that. NameValuePair
takes in String
arguments in the constructor. It makes sense as it is used for HTTP POST.
What you can do is come up with a way to serialize the Report
object into String and send this string as a string parameter. One way of doing this maybe is to delimit the parameters of the Report
class.
reports=reportName1|reportName2|reportName3
Assuming reports
is your ArrayList
,
String reportsStr = "";
for(int i = 0; i < reports.size(); i++) {
reportStr += reportName;
if(i != reports.size() - 1) {
reportsStr += "|";
}
}
NameValuePair nvPair = new NameValuePair("reports", reportsStr);
