可以通过谷歌自带的浏览器工具去分析，get与pos 的传递参数和方式等详细信息的分析。

自定义工具选项——更多工具——开发者工具来调出来，热键：ctrl+shift+i;

------------------------------------------------------------------------------

httpclient:

可以快速的进行访问服务器应用层的操作，http://hc.apache.org/downloads.cgi下载httpclient说明文档。

------------------------------------------------------------------------------

用Httpclient传递参数：

----------------------------------------------------------------------------------------------------------

1、用get方式传参：---------------HttpClientThread01 界面

public class HttpClientThread01 extends Thread {

private String url = null;

public HttpClientThread01(String url) {
this.url = url;
}

private void doHttpClientGet() {
HttpGet httpGet = new HttpGet(url);
HttpClient client = new DefaultHttpClient();

  HttpResponse response = null;
  try {
   response = client.execute(httpGet);

if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
String content = EntityUtils.toString(response.getEntity());

System.out.println("content=========>" + content);
}

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

}

@Override
public void run() {
doHttpClientGet();
}
}

-------------------------MainActivity---------------------

public void onClick(View v) {

    String name = usernameregister.getText().toString().trim();
    String pass = passwordregister.getText().toString().trim();
    String companystr = company.getText().toString().trim();
    String companyidstr = companyid.getText().toString().trim();
    String telephonestr = telephone.getText().toString().trim();
    String agestr = age.getText().toString().trim();
    String sexstr = ((RadioButton) RegisterActivity.this
      .findViewById(sexRegister.getCheckedRadioButtonId()))
      .getText().toString().trim();

//调用HttpClientThread01(get)方法向服务器提交数据。
String url=url + "?name=" + name + "&psd=" + pass + "&companyname=" + companystr + "&companyid=" + companyidstr + "&telephone=" + telephonestr + "&age=" + agestr + "&sex=" + sexstr; new HttpClientThread01(url).start(); finish();

}

----------------------------------布局就是一个有主界面这些这些字段的布局，textview 加edittext

2、用post的方法传参：

-------------------------MainActivity---------------------

public void onClick(View v) {

try {

//URLEncoder.enconde(name,"utf-8")的意思就是防止出现乱码，适应中文。
     new HttpClientThread01(url, URLEncoder
       .encode(name, "utf-8"), pass, URLEncoder.encode(
       companystr, "utf-8"), companyidstr, telephonestr,
       URLEncoder.encode(sexstr, "utf-8"), agestr).start();
    } catch (UnsupportedEncodingException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }

}

-------------------------HttpClientThread01---------------------

public class HttpClientThread01 extends Thread {

private String url;

// get
public HttpClientThread01(String url) {
this.url = url;
}

private String name, psd, companyname, companyid, telephone, sex, age;

// post
public HttpClientThread01(String url, String name, String psd,
   String companyname, String companyid, String telephone, String sex,
   String age) {
  this.url = url;
  this.name = name;
  this.psd = psd;
  this.companyname = companyname;
  this.companyid = companyid;
  this.telephone = telephone;
  this.sex = sex;
  this.age = age;

}

// doHttpClientPost
private void doHttpClientPost() {
  // 创建HttpClient对象
  HttpClient client = new DefaultHttpClient();
  // 创建HttpPost对象
  HttpPost post = new HttpPost(url);

  // 发送请求通过NameValuePair去存储数据的。
  ArrayList<NameValuePair> list = new ArrayList<NameValuePair>();
  list.add(new BasicNameValuePair("name", name));
  list.add(new BasicNameValuePair("psd", psd));
  list.add(new BasicNameValuePair("companyname", companyname));
  list.add(new BasicNameValuePair("companyid", companyid));
  list.add(new BasicNameValuePair("telephone", telephone));
  list.add(new BasicNameValuePair("sex", sex));
  list.add(new BasicNameValuePair("age", age));

  try {
   // 设置要发送的数据
   post.setEntity(new UrlEncodedFormEntity(list));
   // 发送请求
   HttpResponse response = client.execute(post);

   // 判断如果发送的请求是SC_OK，表示请求服务器成功
   if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
    // 取出服务器返回的数据(调用EntityUtils.toString的方法，系统自动把getEntity做一系列转发存储到content中)
    String content = EntityUtils.toString(response.getEntity());
    //
    System.out.println("content=========>" + content);
   }

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

}

// doHttpClientGet
private void doHttpClientGet() {
  // 创建HttpGet对象
  HttpGet get = new HttpGet(url);
  // 创建HttpClient对象
  HttpClient client = new DefaultHttpClient();

  HttpResponse response = null;
  try {
   // 发送请求
   response = client.execute(get);
   // 判断类型
   if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
    // 取出服务器返回的数据
    String content = EntityUtils.toString(response.getEntity());
    //
    System.out.println("content=========>" + content);
   }

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

}

@Override
public void run() {
// doHttpClientGet();
doHttpClientPost();
}
}
