OKHTTP3 requesting the network to turn on gzip compression

Frontier

First of all, OKHTTP3 is supported gzip decompression, but we have to understand that it is to support us when initiating the request to automatically join the header, and Accept-Encoding: gzip our server returned when the header Content-Encoding: gzip .
For more in-depth content, you can refer to read the following article, speaking very good!
Talk about HTTP gzip compression with common Android network framework

So, when we submit a lot of data to the server, we want to do the gzip compression of the post data, how to do?
Below is the solution!

Scheme

The official use of custom interceptors is the way!
Source code in:
Okhttp/samples/guide/src/main/java/okhttp3/recipes/requestbodycompression.java
Nonsense not much to say, directly on the code:

1 import java.io.IOException;2 3 import OKHTTP3. Interceptor;4 import OKHTTP3. mediatype;5 import OKHTTP3. Request;6 import OKHTTP3. Requestbody;7 import OKHTTP3. Response;8 import Okio. Bufferedsink;9 import Okio. Gzipsink;Ten import Okio. Okio; One  A  Public classGziprequestinterceptor implements Interceptor { - @Override -      PublicResponse Intercept (Chain Chain) throws IOException { theRequest originalrequest =chain.request (); -         if(Originalrequest.body () = =NULL|| Originalrequest.header ("content-encoding") !=NULL) { -             returnchain.proceed (originalrequest); -         } +  -Request compressedrequest =Originalrequest.newbuilder () +. Header ("content-encoding","gzip") A . Method (Originalrequest.method (), Gzip (Originalrequest.body ())) at . Build (); -         returnchain.proceed (compressedrequest); -     } -  -     Privaterequestbody gzip (final requestbody body) { -         return NewRequestbody () { in @Override -              Publicmediatype ContentType () { to                 returnBody.contenttype (); +             } -  the @Override *              Public Longcontentlength () { $                 return-1;//The compressed data size cannot be known in advancePanax Notoginseng             } -  the @Override +              Public voidWriteTo (Bufferedsink sink) throws IOException { ABufferedsink Gzipsink = Okio.buffer (NewGzipsink (sink)); the Body.writeto (gzipsink); + gzipsink.close (); -             } $         }; $     } -}

Then, when building the okhttpclient, add the Interceptor:

New Okhttpclient.builder ()     . Addinterceptor (new gziprequestinterceptor ())//  Turn on gzip compression ...     . Build ();

Postscript

If you need a content-length content-length, you can view this issue:
