Question

我已经使用 HttpUrlConnection 实现了一个类来从google geocoding api获取一些数据。当我在Android上使用此代码时，它可以正常工作。但是，只要我在另一个＆＃34;正常＆＃34;中使用此代码java程序，我有时会得到状态代码400（BadRequest）。这是我的代码：

HttpURLConnection c = null;
    StringBuilder sb = new StringBuilder();
    try {
        URL u = new URL(url);
        c = (HttpURLConnection) u.openConnection();
        c.setRequestMethod("GET");
        c.setRequestProperty("Content-length", "0");
        c.setUseCaches(false);
        c.setAllowUserInteraction(false);
        c.setConnectTimeout(timeout);
        c.setReadTimeout(timeout);
        c.connect();
        int status = c.getResponseCode();

        switch (status) {
            case HttpURLConnection.HTTP_OK:
            case HttpURLConnection.HTTP_CREATED:
                BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
                String line;
                while ((line = br.readLine()) != null) {
                    sb.append(line + "\n");
                }
                br.close();   
        }
    } catch (SocketTimeoutException ex){
        // Handle ...
    } catch (MalformedURLException ex) {
        // Handle ...
    } catch (IOException ex) {
        // Handle ...
    } finally {
        if (c != null) {
            try {
                c.disconnect();
            } catch (Exception ex) {

            }
        }
    }

每当我使用网络浏览器尝试时，我都有可靠的互联网连接以及我用来接收数据的网址。提前谢谢！

错误请求通常是由于网址不足造成的。正如您所提到的，并非每个URL都会出现此错误，只会显示它们的视图。所以它必须与之相关。请尝试以下代码以确保正在使用的URL的正确编码：

function globalDisable(id,table_column,call_action){
    // call_action is use for calling the related php function
    // table_column is use for calling the column name of that table

    //action_parm = {call_action:'disable',table_column:id}
    var action_parm = {call_action: call_action,
                       table_column: table_column, 
                       user_id: id};
    $.ajax({
        type:'POST',
        url:'post.php',
        data:action_parm,
        success: function(response){
        }
    });
}
