描述

Description

When running Java client on Android, it throws PROTOCOL_ERROR - I think it has something to do with Java client using an old version of OkHttp that has HTTP2.0 bugs

Swagger-codegen version

2.3.1

Swagger declaration file content or url

https://api.cloudmersive.com/convert/docs/v1/swagger

Command line used for generation

java -jar swagger-codegen-cli.jar generate -i https://api.cloudmersive.com/convert/docs/v1/swagger -l java --api-package com.cloudmersive.client --model-package com.cloudmersive.client.model --invoker-package com.cloudmersive.client.invoker --group-id com.cloudmersive --artifact-id cloudmersive-java-api-client --artifact-version 1.1.9 -o .

Steps to reproduce

Generate the client using above command

Create a test project in Android Studio

Immediately see the protocol_error:

com.cloudmersive.client.invoker.ApiException: java.io.IOException: stream was reset: PROTOCOL_ERROR

We also tried generating the client with the other library templates but those don't actually compile - pretty frustrating.

Suggest a fix/enhancement

Change the Java client to use OK HTTP 3.11.0 instead of old 2.75.0 version

研究方向: Locate the build configuration file (build.gradle or pom.xml) for the Java client template in the swagger codegen repository. Update the OkHttp dependency version from 2.75.0 to 3.11.0. After making the change, regenerate the client and test it on an Android project to ensure the PROTOCOL ERROR is resolved. If successful, submit a pull request referencing this issue.
