我在 pom.xml 文件中添加了我的 maven 依赖项。

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

        <version>2.0.0</version>
    </dependency>
  </dependencies>
</project>

我想向 BioID 发出请求以接收 Web Token API。应用程序标识符和秘密当然被省略了。

package com.bioID.app;

import okhttp3.Request;
import okhttp3.Response;
import okhttp3.HttpUrl;
import okhttp3.OkHttpClient;
import okhttp3.Credentials;

public class App 
{   
    public static void main( String[] args )
    {
        System.out.println( "Hello World!" );
    }

    public static String returntoken() {
        // using OkHttpClient from the OkHttp library
        HttpUrl url = HttpUrl.parse("https://bws.bioid.com/extension/token").newBuilder()
                .addQueryParameter("id", APP_IDENTIFIER)
                .build();
        Request request = new Request.Builder()
                .url(url)
                .addHeader("Authorization", Credentials.basic(APP_IDENTIFIER, APP_SECERET))
                .build();
        OkHttpClient client = new OkHttpClient();
        Response response = client.newCall(request).execute();
        String token = response.body().string();
        if (response.code() == 200) {
            System.out.println("token=" + token);
        }
        return token;
    }
}

尽管从依赖项中添加了类并参考了文档，但这以错误 Request.Builder 无法解析为类型结束。这是由于使用了错误的 okio 或 okhttp 库版本。

编译时的错误信息
