var client = new RestClient("https://open.weixin.qq.com"); var request = new RestRequest("/connect/qrconnect", Method.GET); request.AddParameter("appid", appId); request.AddParameter("redirect_uri", redirectUri); request.AddParameter("response_type", "code"); request.AddParameter("scope", scope);这段代码翻译成java

以下是将上述 C# 代码翻译成 Java 的代码：

import okhttp3.*;
import java.io.IOException;

public class Example {
    public static void main(String[] args) throws IOException {
        OkHttpClient client = new OkHttpClient();
        HttpUrl.Builder urlBuilder = HttpUrl.parse("https://open.weixin.qq.com/connect/qrconnect").newBuilder();
        urlBuilder.addQueryParameter("appid", appId);
        urlBuilder.addQueryParameter("redirect_uri", redirectUri);
        urlBuilder.addQueryParameter("response_type", "code");
        urlBuilder.addQueryParameter("scope", scope);
        String url = urlBuilder.build().toString();
        Request request = new Request.Builder()
                .url(url)
                .build();
        Response response = client.newCall(request).execute();
        System.out.println(response.body().string());
    }
}

上述 Java 代码使用了 OkHttp 库发送 HTTP 请求，并使用了 HttpUrl.Builder 对象构建请求的 URL，通过 addQueryParameter 方法添加请求参数。请求的 HTTP 方法为 GET，请求头和请求体均为空。发送请求并获取响应的过程也需要手动编写。
