Can I use the above call to a webscript in the alfresco repository from a dashlet?
Yes, to do that, you should put that as a part of a dashlet javascript (client side .js I think - the one you include in dashlet.get.head.ftl or just include it as inline javascript in dashlet.het.html.ftl).
I tried it but was not successful. Maybe you would know what I have done wrong?following is the webscript I deployed on alfresco:test-post-ws.post.desc.xml
<webscript>
<shortname>Test Post Webscript</shortname>
<description>Test post webscript</description>
<url>/test-post/test-post-ws</url>
<authentication>user</authentication>
<transaction>required</transaction>
</webscript>
test-post-ws.post.desc.xml
<#escape x as jsonUtils.encodeJSONString(x)>
{
"success": ${success?string},
"message": "<#if errormsg??>${errormsg}</#if>"
}
</#escape>
test-post-ws.post.js
var logFile = "test_Log.txt";
var folderPath = "Guest Home";
var folderNode = companyhome.childByNamePath(folderPath);
var outputFile = folderNode.childByNamePath(logFile);
if (outputFile == null) {
outputFile = folderNode.createFile(logFile);
}
if (folderNode === null) {
folderNode = companyhome.createFolder(folderPath);
}
try {
outputFile.content +="\n";
var currentdate = new Date().toGMTString();
outputFile.content += currentdate;
outputFile.content +="\n";
model.success = true;
} catch (e) {
outputFile.content +="exception in test : ";
outputFile.content += new Date().toGMTString();
outputFile.content +="\n";
outputFile.content +="exception occurred: ";
outputFile.content += e.message;
outputFile.content +="\n";
// error
model.success = false;
model.errormsg = "Error - " + e.message;
}
the webscript deployed without problems. following is the dashlet I deployed to test it:test-post-dashlet.get.desc.xml
<webscript>
<shortname>Test Post WS Dashlet</shortname>
<description>Test post ws dashlet</description>
<family>user-dashlet</family>
<url>/test-post/test-post-dashlet</url>
</webscript>
test-post-dashlet.get.html.ftl
<div class="dashlet">
<div class="title">Test Post WS Dashlet</div>
<script type="text/javascript">
function testClicked(form) {
var url = "http://localhost:8080/alfresco/service/test-post/test-post-ws";
alert(url);
var post_field = "foo=1&bar=2";
alert(post_field);
http.open("POST", url, true);
alert("after http.open");
//Send the proper header information along with the request
http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", post_field.length);
http.setRequestHeader("Connection", "close");
http.onreadystatechange = function() {//Call a function when the state changes.
if(http.readyState == 4 && http.status == 200) {
alert(http.responseText);
}
}
http.send(params);
}
</script>
<form id="test-post" action="" method="post">
<p>
<label>Name</label>
<input type="text" name="name" id="name" /> </p>
<p>
<input type="submit" name="submit" id="new-submit" value="save" />
<input type="button" name="test-post-submit" id="test-post-submit" value="test" onClick="testClicked(this.form)" />
<input type="button" name="cancel" id="new-cancel" value="cancel" />
</p>
</form>
</div>
the dashlet deploys and appears on the dashboard without problems. nothing happens after http.open. It doesn't seem to make the connection. Nothing happens on the alfresco webscript side as well. Should I try it in a different way?
