java - Sending images as a base64 string to a google cloud endpoint from cms -


i trying send image cms google cloud endpoint stored in google datastore. image converted base64 string send endpoint. works fine when i'm sending android application when try sending cms throws error. i've had change api method because other api method uses custom object java , cms using javascript. ways have found send image endpoint either string, text or blob.

this part of method on cms sends image endpoint

var testapi = gapi.client.itemapi; var testapimethod = testapi.storeitemfromjs({ "id" : id, "name" : name, "description" : description, "status" : status, "contents" : contents, "resource": {         "image": image }}); testapimethod.execute();

this current api method, can see it's using text image:

@apimethod(name = "storeitemfromjs", path="itembean/store/js") public entity storeitemfromjs(@named("id")string id, @named("name") string name,                               @named("description") string description,                               @named("status") string status,                               @named("contents") string contents, text image) {     datastoreservice datastoreservice = datastoreservicefactory.getdatastoreservice();     transaction txn = datastoreservice.begintransaction();     entity entity;     try {         //key key = keyfactory.createkey("itemlist", "itemrecord");         entity = new entity("itembean", id);         entity.setproperty("id", id);         entity.setproperty("name", name);         entity.setproperty("description", description);         entity.setproperty("status", status);         entity.setproperty("contents", contents);          byte[] bytes = base64.decodebase64(image.getvalue());          blob imageblob = new blob(bytes);          entity.setproperty("image", imageblob);         datastoreservice.put(entity);         txn.commit();     } {         if (txn.isactive()) {             txn.rollback();         }     }     return entity; }

this gets 503(ok) error when try run it.

when try using blob throws error when try rebuild project , can't find way resolve it. wanted use blob because that's how it's sent from application, don't mind how gets sent long can retrieved , displayed later. error:

error:execution failed task ':backend:appengineendpointsgetclientlibs'.

there error running endpoints command get-client-lib: 400 bad request {"error": {"message": "bad request", "code": 400, "errors": [{"message": "api exception", "debug_info": "cannot decode json schema for: {u'parametername': u'resource'}"}]}}

when tried using string works fine if string being sent short enough (after experimentation found has 2280 characters or less) otherwise throws 400 error. images being sent longer 2280 isn't going work.

update:

from saiyr's suggestion changed code , seems work:

updated endpoint:

@apimethod(name = "storeitemfromjs", path="itembean/store/js")// stores item passed in on datastore public entity storeitemfromjs(@named("id")string id, @named("name") string name,                               @named("description") string description,                               @named("status") string status,                               @named("contents") string contents, request image)

request class:

public class request { public blob image; }

and changes javascript:

var testapi = gapi.client.itemapi; var testapimethod = testapi.storeitemfromjs({ "id" : id, "name" : name, "description" : description, "status" : status, "contents" : contents, "image" : image }); testapimethod.execute();

any appreciated. see right option sending images text have no idea 503 error is, aside being server-side.

thanks tom

i believe (but can't sure, because there not enough information) there bug in api config generation. text isn't allowed resource in endpoints. resources must json objects, not primitives. suggest making class request { blob image; } (expand standard java like) , shouldn't need create new blob. change resource take request type:

@apimethod(name = "storeitemfromjs", path="itembean/store/js") public entity storeitemfromjs(..., request request)

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
