rest - 黑莓 HttpConnection 和查询字符串

Question

当我附加一个查询字符串时，我在连接到 uri 时遇到了一些问题......我总是返回 400 个 http 代码......但是当我尝试浏览器时，相同的 url，一切都很顺利......

这就是我所拥有的：

String query = "q=hello";
byte[] queryBytes = query.getBytes();

在我的代码中的某处，我使用这样的 queryBytes 打开一个 HttpConnection：

String uri = "https://www.google.co.ve/search" + "?" + new String(queryBytes);
HttpConnection request = (HttpConnection) Connector.open(uri);
request.getResponseCode();

如果我不使用字节进行连接，一切都可以正常工作：

String uri = "https://www.google.co.ve/search?q=hello";

提前致谢

Answer 1

当我尝试这个时，我得到了 http 代码 200。

try {
    String httpURL = "https://www.google.co.ve/search?q=hello";
    HttpConnection httpConn;
    httpConn = (HttpConnection) Connector.open(httpURL);
    httpConn.setRequestMethod(HttpConnection.GET);
    DataOutputStream _outStream = new DataOutputStream(httpConn.openDataOutputStream());
    byte[] request_body = httpURL.getBytes();
    for (int i = 0; i < request_body.length; i++) {
        _outStream.writeByte(request_body[i]);
    }
    DataInputStream _inputStream = new DataInputStream(
    httpConn.openInputStream());
    StringBuffer _responseMessage = new StringBuffer();
    int ch;
    while ((ch = _inputStream.read()) != -1) {
        _responseMessage.append((char) ch);
    }
    String res = (_responseMessage.toString());
    String responce = res.trim();
    httpConn.close();

    Dialog.alert(responce);

} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
