Hi coders, i make 2 handlers to abe.py, they output in json addressbalance and unspent TX of especific asset, this information its nesesary to build transaction on cold enviroment.
Hope it helps someone.
def handle_getaddressbalances(abe, page):
chain = page['chain']
page['template'] = "%(body)s"
page['body'] = "";
#page['body'] += "ok";
#page['body'] +=json.dumps({'4': 5, '6': 7}, sort_keys=True,indent=4, separators=(',', ': '));
data = {};
data["result"] = [];
address = wsgiref.util.shift_path_info(page['env'])
if address in (None, '') or page['env']['PATH_INFO'] != '':
raise PageNotFound()

(abe.store.binin(pubkeyhash),) )
assets_resp = abe.store.get_assets(chain)
if len(assets_resp) is 0:
body += ['None']
elif row is not None:
pubkey_id = int(row[0])
assetdict = {}
for asset in assets_resp:
# use escaped form as dict key
name = asset.get('name','').encode('unicode-escape')
assetdict[name] = asset
print(assetdict);
