Hi,
I need to connect to the basic alfresco repository using the CMIS API URL using Atompub or browser binding.
I tried connecting to the repository using the URLs provided in the alfresco documentation.
URLs :
http://<hostname>:<port>/alfresco/api/-default-/public/cmis/versions/1.1/atom
http://<hostname>:<port>/alfresco/api/-default-/public/cmis/versions/1.1/browser
But I am facing an error related to http authentication
{ "status" : { "code" : 401, "name" : "Unauthorized", "description" : "The request requires HTTP authentication." }, "message" : "11210005 Authentication failed for Web Script org\/alfresco\/api\/opencmis\/OpenCMIS.get", "exception" : "", "callstack" : [ ], "server" : "Enterprise v6.2.0 (ra498a911-b5) schema 13,001", "time" : "21 Dec 2020, 07:33:37" }
How can I solve this error, where do I need to auntheticate this?
Try to call with basic authentication.
Please paste your code here
{ "status" : { "code" : 401, "name" : "Unauthorized", "description" : "The request requires HTTP authentication." }, "message" : "11210005 Authentication failed for Web Script org\/alfresco\/api\/opencmis\/OpenCMIS.get", "exception" : "", "callstack" : [ ], "server" : "Enterprise v6.2.0 (ra498a911-b5) schema 13,001", "time" : "21 Dec 2020, 07:33:37" }
Your error indicates authentication failure, possible that you are using invalid credentials.
There is another good way to work with CMIS api, read this tutorial:
Example source code:
On the other hand, either of the URLs should work if you trying to access via some client. As indicated by the folks, you can use basic authentication or alf_ticket (get it using login api) to access the atompub url using any client/java code. Use the httppost request if using basic auth. It is not recommended to use basic auth with httpget in general.
POST http://127.0.0.1:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom
Also refer this doc: https://docs.oasis-open.org/cmis/CMIS/v1.1/errata01/os/CMIS-v1.1-errata01-os-complete.html
this url based on browser binding is meant to be accessed from browser/httpget request. httpPost request is not supported for this url. Hence you can get the alf_ticket and pass along with the url to access the endpoint:
e.g.:
GET http://127.0.0.1:8080/alfresco/api/-default-/public/cmis/versions/1.1/browser?alf_ticket=TICKET_8d8aa27acc731f99c77e3fb670c5c40a6642d039
Some java based httpclient examples for your reference:
public static void main(String[] args) throws ClientProtocolException, IOException { //Basic auth example CloseableHttpClient httpclient = null; try { final CredentialsProvider provider = new BasicCredentialsProvider();
//non admin user final UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("testUser", "welcome"); provider.setCredentials(AuthScope.ANY, credentials); httpclient = HttpClientBuilder.create().setDefaultCredentialsProvider(provider).build(); atomPubTestBasicAuth(httpclient); } finally { if (httpclient != null) { httpclient.close(); } } //Example via alf_ticket browserBindingTest(); } private static void atomPubTestBasicAuth(final CloseableHttpClient httpclient) throws IOException, ClientProtocolException { System.out.println("Invoking atomPubTestBasicAuth..");
//atompub url example final HttpPost httpPost = new HttpPost("http://127.0.0.1:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom"); try(CloseableHttpResponse httpResp = httpclient.execute(httpPost);) { if (httpResp != null) { final StatusLine statusLine = httpResp.getStatusLine(); final String statusMsg = statusLine.getReasonPhrase(); final int statusCode = statusLine.getStatusCode(); System.out.println("StatusMsg: "+statusMsg+", StatusCode: "+statusCode); if (statusCode == 200) { // process further } else { //report error } } } } private static void browserBindingTest() throws IOException, ClientProtocolException { System.out.println("Invoking browserBindingTest.."); try (final CloseableHttpClient httpclient = HttpClientBuilder.create().build();) {
//example browser binding url final HttpGet httpGet = new HttpGet("http://127.0.0.1:8080/alfresco/api/-default-/public/cmis/versions/1.1/browser?alf_ticket=TICKET_8d8aa27acc731f99c77e3fb670c5c40a6642d039"); try(CloseableHttpResponse httpResp = httpclient.execute(httpGet);) { if (httpResp != null) { final StatusLine statusLine = httpResp.getStatusLine(); final String statusMsg = statusLine.getReasonPhrase(); final int statusCode = statusLine.getStatusCode(); System.out.println("StatusMsg: "+statusMsg+", StatusCode: "+statusCode); if (statusCode == 200) { // process further } else { //report error } } } } }
