HttpURLConnection 如何设置编码格式为unicode提交参数

公司用HttpURLConnection去调用第三方的接口，然后呢人家的编码格式是unicode格式的
而且还是http-get请求。我拿到的数据是utf-8的中文字符串。想问下大佬要怎么改。
谢谢谢谢！

你是java 吧，想转换下字符的编码吧，
如果以前是GBK可以转到UTF-8
变量str以前是GBK编码
byte[] data=str.getBytes("GBK");
String strUTF8=new String(data, ‘UTF-8");

这要就可以互相转换了，如果是直接想用
byte[] data=strUTF8.getBytes("UTF-8");

URL.openConnection()得到一个URLConnection对象,然后用URLConnection.setRequestProperty()来设置头信息

HttpURLConnection conn = (HttpURLConnection) realUrl.openConnection();

// 发送POST请求必须设置如下两行
conn.setDoOutput(true);
conn.setDoInput(true);
conn.setRequestMethod("POST");

out = new OutputStreamWriter(conn.getOutputStream(), "UTF-8");

可以指定body的编码

out = new PrintWriter(conn.getOutputStream());

PrintWriter不能指定编码，只能使用参数中的流（Stream）中的编码，是什么就用什么

这个应该好处理，使得两边编码一致即可。对面服务器没法改，那就只要修改自己的的编码方式了哦。楼上介绍的都可以

    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
    connection.setDoOutput(false);//post请求改为TRUE
    connection.setDoInput(true);
    connection.setRequestMethod("GET");
    connection.setUseCaches(false);
    connection.setInstanceFollowRedirects(true);
    connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded;charset=utf-8");
    connection.setRequestProperty("Charset", "utf-8");
    connection.setRequestProperty("Accept-Charset", "utf-8");
    connection.setReadTimeout(5000);
    connection.setConnectTimeout(5000);
    connection.connect();

    if (connection.getResponseCode() == 200) {
        BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"));
        String line;
        while ((line = in.readLine()) != null) {
            result += line;
        }
        return result;
    }

URLEncoder.encode(str,"UTF-8");
