  16. Guidelines • Deposits • 2 or more deposits can be running simultaneously, • A temp file is created using the HTTP fname parameter … prevents two files with the same name from being deposited at the same time • XSD, operation=doXSDMDUpload : DTD, operation=doMDUpload • Queries • Try to avoid many requests with only one query (group in 10+) • Upload very large (1000+) queries using asynchronous query interface • Reduce dependence on mddb.xml pre-filtering, submit more queries • OpenURL Query Format • DON’T : id=doi:10.1061/(ASCE)0893-1321(2002)15:4(125) OpenURL query problems and deposits , there is no DOI: in a DOI value • DO : id=10.1061/(ASCE)0893-1321(2002)15:4(125) 2002 CrossRef Annual Member Meeting Implementation Workshop

  17. Programming - Perl • Query as an HTTP POST #!/usr/bin/perl -w use strict; use LWP::UserAgent; use URI::Escape; require HTTP::Headers; my $h = HTTP::Headers->new; $h->header('Content-Type' => 'application/x-www-form-urlencoded'); my $user=“XXXX"; my $pass=“yyyyy"; my $query="00218561|||50|16|4713|||1| …. my $verysafe = uri_escape($query, "| \n"); 2002 CrossRef Annual Member Meeting Implementation Workshop

  18. Programming - Perl • Query as an HTTP POST cont. my $user_agent = new LWP::UserAgent; $user_agent->agent(“Your agent name".$user_agent->agent); $user_agent->timeout(360); my $req = new HTTP::Request 'POST', 'http://mddb2.crossref.org /query/xref.cgi', $h; $req->content("usr=$user&pwd=$pass&db=mddb&qdata=$query"); # Send query to the server my $response; $response = $user_agent->request($req); 2002 CrossRef Annual Member Meeting Implementation Workshop

  19. Programming - Java • Deposit as an HTTP POST import HTTPClient.*; import java.net.*; … public class doDeposits { HTTPClient.NVPair[] uploadOpts = new HTTPClient.NVPair[2]; HTTPClient.NVPair[] uploadFileOpts = new HTTPClient.NVPair[1]; uploadOpts[0] = new HTTPClient.NVPair ("operation","doMDUpload"); uploadOpts[1] = new HTTPClient.NVPair ("area","live"); uploadFileOpts[0] = new HTTPClient.NVPair ("fname",XMLFile); HTTPClient.NVPair[] ct_hdr = new HTTPClient.NVPair[1]; byte[] uploadBytes; 2002 CrossRef Annual Member Meeting Implementation Workshop

  20. Programming - Java • Deposit as an HTTP POST cont HTTPClient.HTTPConnection httpConn = new HTTPClient.HTTPConnection (host,port); uploadBytes = HTTPClient.Codecs.mpFormDataEncode (uploadOpts,uploadFileOpts,ct_hdr); HTTPClient.CookieModule.setCookiePolicyHandler(null); HTTPClient.HTTPResponse httpResp = null; httpResp = httpConn.Post ("/servlet/deposit?login_id=" + username + "&login_passwd=" + password,uploadBytes,ct_hdr); …. • Requires HTTPClient.jar http://www.innovation.ch/java/HTTPClient/ • Down load sample code from our site http://mddb2.crossref.org/doc/samples.zip 2002 CrossRef Annual Member Meeting Implementation Workshop

  21. Programming - VB • Query as an HTTP GET Set WinHttpReq = New WinHttpRequest (need winhttp50sdk.exe) WinHttpReq.SetTimeouts 0, 60000, 60000, 300000 WinHttpReq.Open "GET", _ "http://mddb2.crossref.org/query/xref.cgi?usr=" + username.Text + _ "&pwd=" + password.Text + "&area=" + area + "&fuzzy=true&type=" + _ “operation + "&qdata=" + qData” , False WinHttpReq.Send results = WinHttpReq.ResponseText 2002 CrossRef Annual Member Meeting Implementation Workshop

  22. Programming - VB • Deposit as an HTTP POST Set WinHttpReq = New WinHttpRequest (need winhttp50sdk.exe) WinHttpReq.SetTimeouts 0, 60000, 60000, 300000 WinHttpReq.Open "POST", "http://mddb2.crossref.org/servlet/deposit", False WinHttpReq.SetRequestHeader "Pragma", "no-cache" WinHttpReq.SetRequestHeader "Content-Type", "multipart/form-data; boundary=-------------------------7d23583220204" formData = formData + "---------------------------7d23583220204" + vbCrLf formData = formData + "Content-Disposition: form-data; name=" + Chr(34) + "login_id" + Chr(34) + vbCrLf formData = formData + vbCrLf formData = formData + username.Text + vbCrLf WinHttpReq.Send formData HTML.DocumentHTML = WinHttpReq.ResponseText 2002 CrossRef Annual Member Meeting Implementation Workshop
