So i'have a Alfresco Community server (5.2.X and 6.2.X), i have prepared a retrofit2 client for communicate with the rest api of Alfresco, it's work just fine with all the services, but there is some strange error when i try to upload a file with the "createNode" post method of the rest api with contentype "multipart/form-data".
Here the retrofit 2 code for upload a file with the rest api:
@Multipart @POST("nodes/{nodeId}/children") Call<NodeEntry> createNodeCall( @retrofit2.http.Path("nodeId") String nodeId, //@retrofit2.http.Body NodeBodyCreate nodeBodyCreate, //Removed because is the multipart/form-data @retrofit2.http.Query("autoRename") Boolean autoRename, @retrofit2.http.Query("include") CSVParams include, @retrofit2.http.Query("fields") CSVParams fields, @retrofit2.http.PartMap() Map<String, RequestBody> partMap, //Added because is the multipart/form-data @retrofit2.http.Part MultipartBody.Part filedata //Added because is the multipart/form-data );
Here the content of the "partMap" map:
"name" = "ifc-32.png" "nodeType" = "cm:content" "relativePath" = null "association" = null "secondaryChildren" = null "targets" = null other properties with key-value relationship but in this case there are no ones...
The strange thing is i doesn't get a 404 or 401 or some other common issue, but instead Alfresco tell me this strange error:
{ "error":{ "errorKey":""cm:content" isn't a valid QName. Namespace prefix "cm is not mapped to a namespace URI", "statusCode":400, "briefSummary":"10130018 "cm:content" isn't a valid QName. Namespace prefix "cm is not mapped to a namespace URI", "stackTrace":"Per motivi di sicurezza l'analisi dello stack non viene più visualizzata, ma viene mantenuta la proprietà per le versioni precedenti", "descriptionURL":"https://api-explorer.alfresco.com" } }
What that is mean??? "cm:content" is the de facto standard type of documents... i don't understand...
The default value is still "cm:content" so i just set :
"nodeType" = null
and try again.
After that a similar error is showed up for the "name" parameter. Here the error i get after send the nodetype and name with null value:
{ "error":{ "errorKey":"framework.exception.ApiDefault", "statusCode":422, "briefSummary":"10130069 Found 1 integrity violations: Invalid property value: Node: workspace://SpacesStore/ed95ec75-0240-40ed-8f36-c7ad19cd3262 Name: "ifc-32.png" Type: {http://www.alfresco.org/model/content/1.0}content Property: {http://www.alfresco.org/model/content/1.0}name Constraint: 10130068 Value '"ifc-32.png"' is not valid as a file name. This property must be a valid file name.", "stackTrace":"Per motivi di sicurezza l'analisi dello stack non viene più visualizzata, ma viene mantenuta la proprietà per le versioni precedenti", "descriptionURL":"https://api-explorer.alfresco.com" } }
So i removed the name parameter :
"name" = null
and now it's finally work why ???

The error was strange but it's seems not present on Alfresco 6 so my soltuion is if you encounter this problem update Alfresco 5 to Alfresco 6

Try comparing the documentation here:
https://docs.alfresco.com/5.2/concepts/dev-api-by-language-alf-rest-mng-folders-files.html
https://docs.alfresco.com/5.2/concepts/dev-api-by-language-alf-rest-upload-file.html
It works fine on 5.2.x and 6.x just fine via POSTMAN and CURL.
