android向web提交参数的4种方式总结，附带网站案例源码

第一种：基于http协议通过get方式提交参数

1.对多个参数的封装

 1 public static String get_save(String name, String phone) {
 2         /**
 3          * 出现乱码原因有2个 提交参数没有对中文编码，解决方法：使用URLEncoder.encode(xx,xx)对要提交的汉字转码
 4          * tomatCAT服务器默认采用iso859-1编码，解决方法：把PHP页面保存为UTF-8格式
 5          */
 6         String path = "http://192.168.0.117/testxml/web.php";
 7         Map<String, String> params = new HashMap<String, String>();
 8         try {
 9             params.put("name", URLEncoder.encode(name, "UTF-8"));
10             params.put("phone", phone);
11             return sendgetrequest(path, params);
12         } catch (Exception e) {
13             // TODO Auto-generated catch block
14             e.printStackTrace();
15         }
16         return "提交失败";
17     }

2.提交参数

 1 private static String sendgetrequest(String path, Map<String, String> params)
 2             throws Exception {
 3 
 4         // path="http://192.168.0.117/testxml/web.php?name=xx&phone=xx";
 5         StringBuilder url = new StringBuilder(path);
 6         url.append("?");
 7         for (Map.Entry<String, String> entry : params.entrySet()) {
 8             url.append(entry.getKey()).append("=");
 9             url.append(entry.getValue()).append("&");
10         }
11         url.deleteCharAt(url.length() - 1);
12         URL url1 = new URL(url.toString());
13         HttpURLConnection conn = (HttpURLConnection) url1.openConnection();
14         conn.setConnectTimeout(5000);
15         conn.setRequestMethod("GET");
16         if (conn.getResponseCode() == 200) {
17             InputStream instream = conn.getInputStream();
18             ByteArrayOutputStream outstream = new ByteArrayOutputStream();
19             byte[] buffer = new byte[1024];
20             while (instream.read(buffer) != -1) {
21                 outstream.write(buffer);
22             }
23             instream.close();
24             return outstream.toString().trim();
25 
26         }
27         return "连接失败";
28     }

sendgetrequest

第二种：基于http协议通过post方式提交参数

1.对多个参数封装

 1 public static String post_save(String name, String phone) {
 2         /**
 3          * 出现乱码原因有2个 提交参数没有对中文编码，解决方法：使用URLEncoder.encode(xx,xx)对要提交的汉字转码
 4          * tomatCAT服务器默认采用iso859-1编码，解决方法：把PHP页面保存为UTF-8格式
 5          */
 6         String path = "http://192.168.0.117/testxml/web.php";
 7         Map<String, String> params = new HashMap<String, String>();
 8         try {
 9             params.put("name", URLEncoder.encode(name, "UTF-8"));
10             params.put("phone", phone);
11             return sendpostrequest(path, params);
12         } catch (Exception e) {
13             // TODO Auto-generated catch block
14             e.printStackTrace();
15         }
16         return "提交失败";
17     }

post_save

2.提交参数

 1 private static String sendpostrequest(String path,
 2             Map<String, String> params) throws Exception {
 3         // name=xx&phone=xx
 4         StringBuilder data = new StringBuilder();
 5         if (params != null && !params.isEmpty()) {
 6             for (Map.Entry<String, String> entry : params.entrySet()) {
 7                 data.append(entry.getKey()).append("=");
 8                 data.append(entry.getValue()).append("&");
 9             }
10             data.deleteCharAt(data.length() - 1);
11         }
12         byte[] entiy = data.toString().getBytes(); // 生成实体数据
13         URL url = new URL(path);
14         HttpURLConnection conn = (HttpURLConnection) url.openConnection();
15         conn.setReadTimeout(5000);
16         conn.setRequestMethod("POST");
17         conn.setDoOutput(true);// 允许对外输出数据
18         conn.setRequestProperty("Content-Type",
19                 "application/x-www-form-urlencoded");
20         conn.setRequestProperty("Content-Length", String.valueOf(entiy.length));
21         OutputStream outstream = conn.getOutputStream();
22         outstream.write(entiy);
23         if (conn.getResponseCode() == 200) {
24             InputStream instream = conn.getInputStream();
25             ByteArrayOutputStream byteoutstream = new ByteArrayOutputStream();
26             byte[] buffer = new byte[1024];
27             while (instream.read(buffer) != -1) {
28                 byteoutstream.write(buffer);
29             }
30             instream.close();
31             return byteoutstream.toString().trim();
32         }
33         return "提交失败";
34     }

sendpostrequest（）

第三种：基于httpclient类通过post方式提交参数

1.对多个参数的封装

 1 public static String httpclient_postsave(String name, String phone) {
 2         /**
 3          * 出现乱码原因有2个 提交参数没有对中文编码，解决方法：使用URLEncoder.encode(xx,xx)对要提交的汉字转码
 4          * tomatCAT服务器默认采用iso859-1编码，解决方法：把PHP页面保存为UTF-8格式
 5          */
 6         String path = "http://192.168.0.117/testxml/web.php";
 7         Map<String, String> params = new HashMap<String, String>();
 8         try {
 9             params.put("name", name);
10             params.put("phone", phone);
11             return sendhttpclient_postrequest(path, params);
12         } catch (Exception e) {
13             // TODO Auto-generated catch block
14             e.printStackTrace();
15         }
16         return "提交失败";
17     }

httpclient_postsave

2.提交参数

 1 private static String sendhttpclient_postrequest(String path,Map<String, String> params) {
 2         List<NameValuePair> pairs = new ArrayList<NameValuePair>();
 3             for (Map.Entry<String, String> entry : params.entrySet()) {
 4                 pairs.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
 5             }
 6         try {
 7             UrlEncodedFormEntity entity=new  UrlEncodedFormEntity(pairs,"UTF-8");
 8             HttpPost httpost=new HttpPost(path);
 9             httpost.setEntity(entity);
10             HttpClient client=new DefaultHttpClient();
11             HttpResponse response= client.execute(httpost);
12         if(response.getStatusLine().getStatusCode()==200){
13             
14             return EntityUtils.toString(response.getEntity(), "utf-8");
15         }
16         } catch (Exception e) {
17             // TODO Auto-generated catch block
18             e.printStackTrace();
19         }
20 
21         return null;
22     }

sendhttpclient_postrequest（）

第四种方式：基于httpclient通过get提交参数

1.多个参数的封装

 1 public static String httpclient_getsave(String name, String phone) {
 2         /**
 3          * 出现乱码原因有2个 提交参数没有对中文编码，解决方法：使用URLEncoder.encode(xx,xx)对要提交的汉字转码
 4          * tomatCAT服务器默认采用iso859-1编码，解决方法：把PHP页面保存为UTF-8格式
 5          */
 6         String path = "http://192.168.0.117/testxml/web.php";
 7         Map<String, String> params = new HashMap<String, String>();
 8         try {
 9             params.put("name", name);
10             params.put("phone", phone);
11             return sendhttpclient_getrequest(path, params);
12         } catch (Exception e) {
13             // TODO Auto-generated catch block
14             e.printStackTrace();
15         }
16         return "提交失败";
17     }

httpclient_getsave

2.提交参数

 1     private static String sendhttpclient_getrequest(String path,Map<String, String> map_params) {
 2         List<BasicNameValuePair> params = new ArrayList<BasicNameValuePair>();
 3             for (Map.Entry<String, String> entry : map_params.entrySet()) {
 4                 params.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
 5             }
 6         String param=URLEncodedUtils.format(params, "UTF-8");
 7         HttpGet getmethod=new HttpGet(path+"?"+param);
 8         HttpClient httpclient=new DefaultHttpClient();
 9         try {
10             HttpResponse response=httpclient.execute(getmethod);
11             if(response.getStatusLine().getStatusCode()==200){
12                 return EntityUtils.toString(response.getEntity(), "utf-8");                
13             }            
14         } catch (ClientProtocolException e) {
15             // TODO Auto-generated catch block
16             e.printStackTrace();
17         } catch (IOException e) {
18             // TODO Auto-generated catch block
19             e.printStackTrace();
20         }        
21         return null;
22     }
