Question

我正在尝试在项目中使用第三方API，以便以虚张声势提供访问这些api的方式

当我使用swagger生成客户端并尝试在我的本地使用时，我收到错误

我正在尝试使用生成的客户端中的一种方法，如下所示

package io.swagger.client.api;

import com.squareup.okhttp.OkHttpClient;
import io.swagger.client.ApiClient;
import io.swagger.client.ApiException;
import io.swagger.client.Configuration;
import io.swagger.client.model.AppModel;
import io.swagger.client.model.NodeModel;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;

public class testSample {
    private final PlatformApi api = new PlatformApi();
    public void getNodesTest() throws ApiException {
        List<AppModel> response = api.getApps();
        System.out.print("------------------------inside testsample------------------------");
        System.out.print(response);
    }

    public static void main(String args[]){
        testSample t1=new testSample();
        System.out.print("------------------------inside main------------------------");
        try{
            ApiClient defaultApiClient = Configuration.getDefaultApiClient();
            ApiClient apiClient = t1.api.getApiClient();
            System.out.println(defaultApiClient);
            System.out.println(apiClient);
            t1.getNodesTest();
        }
        catch(Exception e){
            System.out.println("inside exeption");
            e.printStackTrace();
        }



    }
}

请提供一些建议如何在本地

中使用swagger生成的java客户端

Answer 1

我希望这些可以帮助某人;

DefaultApi defaultApi = new DefaultApi();
ApiClient apiClient = new ApiClient();
apiClient.setBasePath("http://....");
apiClient.addDefaultHeader("Authorization", "bearer TOKEN");
OkHttpClient httpClient = apiClient.getHttpClient();
httpClient.setConnectTimeout(60, TimeUnit.SECONDS);
httpClient.setReadTimeout(60, TimeUnit.SECONDS);
httpClient.setWriteTimeout(60, TimeUnit.SECONDS);
defaultApi.setApiClient(apiClient);

SomeModel var1 = defaultApi.getNodesTest();

generator sample命令;

> java -jar swagger-codegen-cli-2.2.2.jar generate -l java -o myModule --library okhttp-gson -i http://..../swagger

下载jar文件;

Answer 2

以下错误表明Java API客户端无法连接到API服务器：

io.swagger.client.ApiException: java.net.SocketTimeoutException: connect timed out

我建议您验证Swagger / OpenAPI规范，以确保其设置正确host，例如：

host: petstore.swagger.io

e.g。 https://github.com/swagger-api/swagger-codegen/blob/master/modules/swagger-codegen/src/test/resources/2_0/petstore.yaml#L12

参考：Swagger 2.0规范：https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md#swagger-object
