I am sending a big array of data. What is more optimized: to concat data with a symbol or to send it as a JSONArray?
Data is being sent from Android client to Apache PHP.
Example of concated data:
data1_data2_data3_data4
Example of JSONArray
{ "Data": [data1, data2, data3, data4] }
分享 It completely depends on your usecase. From you example, here are some thoughts:
in terms of bytes sent, the concatenation is slightly better, as a JSON adds some metadata and symbols.
In terms of ease of use, JSON clearly wins, as there are libraries and standards. If you just have plain data without any _, concatenated data are ok. But what happens if one of you data has a _ ? You will need to escape those and to keep track of your custom format all over your codes... (And that's just the tip of the iceberg).
In general, my advice is: use standard data serialization schemes, always. In case the size of the serialized data is a concern, have a look at binary standards (for example protobuf).
