python - Python3, json causes TypeError but simplejson doesn't -


i'm running latest python3 (with anaconda distribution) , have problem standard library installed json causes traceback:

    traceback (most recent call last):       file "c:\users\think\anaconda3\lib\site-packages\werkzeug\serving.py", line 193, in run_wsgi         execute(self.server.app)       file "c:\users\think\anaconda3\lib\site-packages\werkzeug\serving.py", line 181, in execute         application_iter = app(environ, start_response)       file "c:\users\think\my_server.py", line 148, in __call__         return self.wsgi_app(environ, start_response)       file "c:\users\think\my_server.py", line 144, in wsgi_app         response = self.dispatch_request(request)       file "c:\users\think\my_server.py", line 80, in dispatch_request         return getattr(self, 'on_' + endpoint)(request, **values)       file "c:\users\think\my_server.py", line 54, in on_xapi_request         json_data = self.load_json(request.data)       file "c:\users\think\my_server.py", line 60, in load_json         return json.loads(data)       file "c:\users\think\anaconda3\lib\json\__init__.py", line 312, in loads         s.__class__.__name__))  typeerror: json object must str, not 'bytes'

but, simplejson doesn't cause error.

use str.decode('utf-8') before passing json.loads

i think line:

return json.loads(data)

is causing problem. decode data before passing function.

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
