There is a clean way to return string as json in a Spring Web API?

由 坚强是说给别人听的谎言 提交于 2021-01-24 08:12:51
问题 For example, I had to implement as below: @RequestMapping(value = "/get-string", method = {RequestMethod.GET}) public @ResponseBody String getString() { return "Hello World!"; } When the action is called by Ajax in a JS file, the response received is: HelloWorld . So, if the Ajax request is configured to only receive json encoded responses, I receive the standard deconding error. To solve this problem in server-side, I need to receive "HelloWorld" . My question is: There is a clean way I can

DRF create method in viewset or in serializer

由 女生的网名这么多〃 提交于 2021-01-24 07:08:07
问题 What is the difference between customizing the "create" method in DRF viewset or customizing it in the serializer? I understand the serializer is responsible to deserialize the data, i.e. the way the data is presented in the POST query; however, I can also create objects in related fields in the serializer. #views.py def create(self, request): pass #serializer.py def create(self, validated_data): return Model.objects.create(**validated_data) When should I customize views/create vs. serializer

Serialize XML with XML string

由 旧时模样 提交于 2021-01-21 07:43:48
问题 I have to produce the following XML <object> <stuff> <body> <random>This could be any rondom piece of unknown xml</random> </body> </stuff> </object> I have mapped this to a class, with a body property of type string. If I set the body to the string value: " <random>This could be any rondom piece of unknown xml</random> " The string gets encoded during serialization. How can I not encode the string so that it gets written as raw XML? I will also want to be able to deserialize this. 回答1:

How to serialize/deserialize Pandas DataFrame to and from ProtoBuf/Gzip in a RESTful Flask App?

由 牧云@^-^@ 提交于 2021-01-21 01:45:11
问题 I have a pandas dataframe to be returned as a Flask Response object in a flask application. Currently I am converting it to a JSON Object , df = df.to_json() return Response(df, status=200, mimetype='application/json') The dataframe size is really huge of the magnitude, probably 5000000 X 10. On the client side when I deserialize it as, df = response.read_json() As my number of URL request parameters grow, the dataframe grows as well. Deserialization time grows at a linear factor as compared

问题 We have data coming from 3rd party system and I have one class designed like this, public class CollectionProperty { public string Name { get; set; } public object Value { get; set; } } and my VS debugger saying value like this which gives me extra details of data type along with result, Now when I serialize this using Newtonsoft, var x = JsonConvert.SerializeObject(resultPacket); it's giving below output with only value kind and NOT the value. I need string value with double quote, number

Unexpected serialization behavior with configured Jackson ObjectMapper

由 与世无争的帅哥 提交于 2021-01-07 03:21:40
问题 I am using Jackson 2.10.5 to serialize the same java.util.Date object three times. The first time, with a basic Jackson ObjectMapper . I see the timestamp. Then I configure the same ObjectMapper , and rewrite. I get the same result. Then I construct a new ObjectMapper , configure it the same way. I get a different result, the class name and the timestamp in a JSON list. The configuration is intended to tell the ObjectMapper to include the class name of every object except java.util.Date as a

问题 I'm trying to create a live chat application using ws4py (if there are better socket libraries I would love recommendations) and I want to implement file transfer (specifically .wav files) in my application. For text chat messages I'm currently using the JSON library to send a serialized dictionary over my sockets and decode them on either side. Something like this message = raw_input("Message: ") payload = {"username": self.username, "message": message} payload["type"] = constants.CHAT
