java - 西类牙字符和 URISyntaxException

Question

我正在研究西类牙语版本的搜索，每当用户输入西类牙语字符(比如 HÍBRIDOS)时，我都会看到一些异常(如下所示)。在下面显示我的编码方式。发送的 url 是通过线路发送的，如图所示。

url=http://wwwdev.searchbridg.com/absd/JSONControllerServlet.do?&N=0&Ntk=AllText&Ntt=HÃBRIDOS&Nty=1&Ntx=mode+matchall

  DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpParams params = httpClient.getParams();
    try {
        HttpConnectionParams.setConnectionTimeout(params, 10000);
        HttpConnectionParams.setSoTimeout(params, 10000);
    } catch (Exception e) {
        e.printStackTrace();
        throw e;
    }
    HttpHost proxy = new HttpHost(getProxy(), getProxyPort());
    ConnRouteParams.setDefaultProxy(params, proxy);
    URI uri;
    InputStream data = null;
        uri = new URI(url);
        HttpGet method = new HttpGet(uri);
        HttpResponse response=null;
        try {
        response = httpClient.execute(method);
        }catch(Exception e) {
            e.printStackTrace();
            throw e;
        }
        data = response.getEntity().getContent();
    Reader r = new InputStreamReader(data);
    HashMap<String, Object> jsonObj = (HashMap<String, Object>) GenericJSONUtil.fromJson(r);

java.net.URISyntaxException: Illegal character in query at index 101: http://wwwdev.searchbridge.com/abs/JSONControllerServlet.do?&N=0&Ntk=AllText&Ntt=H├?BRIDOS&Nty=1&Ntx=mode+matchall

    at java.net.URI$Parser.parse(URI.java:3021)
    at java.net.URI.<init>(URI.java:578)

我尝试使用 UTF-8 编码进行编码，但仍然无法正常工作，显示相同的异常。 html 页面设置为 <meta charset="utf-8" />

byte[] bytes = url.getBytes("UTF8");
    String stringuRL = new String(bytes,"UTF-8");
        uri = new URI(stringuRL);

如果您根据请求(GET 请求)发送特殊字符，则必须对它们进行 URL 转义。查看此线程以了解操作方法。 HTTP URL Address Encoding in Java

收到请求后，必须做逆向处理才能得到原词。
