android测试HttpPost字符串以进行调试

Question

我正在尝试使用 HttpPost 将数据从我的手机发送到 mysql，但我没有设置任何服务器，所以我想知道我是否可以看到我正在发送的确切内容以及它的外观。我对 JSON 以及它们的外观有点熟悉。所以我很好奇我会发送到 mysql 以进行调试。

public void sendDataDetail(View v){
    String name = nameText.getText().toString();

    if(name.length()>0){
        Log.w(TAG, name);
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://site/post.php");
        Log.w(TAG, "After HttpPost");
        try{
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            Log.w(TAG, "After list");
            nameValuePairs.add(new BasicNameValuePair("location","Los Angeles"));
            Log.w(TAG, "After location");
            nameValuePairs.add(new BasicNameValuePair("item_name",name));
            Log.w(TAG, "After item");
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            Log.w(TAG, "After nameValuePairs");
            httpclient.execute(httppost);
            nameText.setText(""); // clear text box, but this should be back to front page
        }catch(ClientProtocolException e){
            Log.w(TAG, e.getMessage());
        }catch(IOException e ){
            Log.w(TAG, e.getMessage());

        }
    }
}

如您所见，我有一堆日志要测试它是否通过每一行（不确定这是否有必要 =\ ）。我想知道我是否可以看到httppost 的样子，但如果我这样做似乎将无法正常工作

Log.w(TAG, httppost);

我得到了错误。

关于如何测试我发送到 mysql 进行调试的任何建议？

提前致谢

根据您使用的 httpclient 版本，将有多种方式打开 2 个关键记录器：

httpclient.wire.header httpclient.wire

在一种类型的客户端中，您可以使用 java 系统属性来激活相应记录器上的 DEBUG 级别记录，这些记录器几乎总是由 HttpClient（标头和线路）使用...

 System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire.header", "debug");          System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire", "debug");

上述方法并非在所有情况下都有效。例如在 android 上，我使用 client 而且，为了激活 WIRE 和 HEADERS 的日志记录，我必须重新编译第 3 方包，更改 class= ch.boye.httpclientandroidlib.androidextra.HttpClientAndroidLog (Log DEBUG ON | OFF)

两个记录器都打开的 logcat 示例块可以完整地查看 http...

在您的 IDE（例如 Eclipse）中，在 httpclient.execute(httppost); 处放置一个断点

然后在“表达式”窗口中，添加httppost 变量，查看值是什么。

现在你可以摆脱所有的日志记录了
