Create a ‘changeset’ using api

Hi, I'm creating a client for OSM api. I'm failing to create a changeset. (I'm using developers' url). I'm sending followings in header. oauth_token,oauth_consumer_key,oauth_signature_method,oauth_version,oauth_nonce,oauth_timestamp And message body as follows:

<osm>
<changeset><tag k="A" v="Aaa"/><tag k="B" v="Bbb"/><tag k="c" v="Ccc"/></changeset>
<changeset><tag k="B" v="Bbl"/></changeset>
<changeset><tag k="A" v="Aab"/><tag k="F" v="Afff"/><tag k="B" v="bbb"/></changeset>
</osm>

After sending data to server using PUT, I'm receiving http 500 response (Application error).

Could someone help to solve this issue please?

Thanks!

Silly question : which URI are you using ? /api/0.6/changeset/create

Did you try first with only one <changeset> element ?

Hi, url is http://api06.dev.openstreetmap.org/api/0.6/changeset/create Yes, I've tried with only one element too. But the result is same

I don't know exactly the reason for the 500 error code, but you are at least missing the xml tag. Here are the header and body of a PUT request to /api/0.6/changeset/create from a recent JOSM version:

header:

PUT /api/0.6/changeset/create HTTP/1.1
User-Agent: JOSM/1.5 (5587 de)
Connection: close
Authorization: OAuth oauth_token="blah", oauth_consumer_key="blah", oauth_version="1.0", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1353272088", oauth_nonce="blah", oauth_signature="blah"
Content-type: text/xml
Host: api.openstreetmap.org
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Content-Length: 42

body:

<?xml version='1.0' encoding='UTF-8'?>
<osm version='0.6' generator='JOSM'>
  <changeset  id='0' open='false'>
    <tag k='comment' v='my changeset comment' />
    <tag k='created_by' v='JOSM/1.5 (5581 en)' />
  </changeset>
</osm>

Also make sure to always include the comment and created_by tag in your changesets.

Hi, In API spec. it is not mentioned to add xml tag. I failed even it is added. is it necessary to add version,generator attributes to osm tag? and id, open attributes in changeset tag?

I also would appriciate, if you can give me an example of PUT with headers too. (eg: Content-Type,etc.) Thanks!

I've added a header. You can use a program like wireshark or tcpdump yourself to read network packets of JOSM or other programs.

I'm not familiar with the API details so I can't say anything about which XML attributes are required and which not. Just try it if you can't find anything in the API documentation about this.

Hi All, Thanks for the help, specially scai. Message should follow following format in body.

<?xml version="1.0" encoding="UTF-8"?> 
<osm version="0.6" generator="MyOpenstreetmapApp"> 
<changeset>
    <tag k='comment' v='my changeset comment' />
    <tag k='created_by' v='JOSM/1.5 (5581 en)' />   
</changeset> 
</osm>

The above message format worked finally !

The detail is on the wiki page. You need to submit the page with an HTTP PUT.

You may have an authentication problem. Check this page about OAuth in OSM : https://wiki.openstreetmap.org/wiki/OAuth

(15 Nov '12, 12:51) Pieren

Hi, It's not a problem with authentication, since I'm getting a token and a secret after Access Token step. Thanks

i have latitude and longitude of a location. i want to upload xml file about this location to add POI.where should i use lat and long? In changset?

@Er Pawan Verma: to the node object. See the documentation for the API - e.g. about nodes. Please keep in mind that you should not create objects automatically.

Please don't hijack other people's question. Ask a new question instead (which you already did here).
