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
public static String get_save(String name, String phone) {
/**
* 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
* 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
*/
String path = "http://192.168.0.117/testxml/web.php";
Map<String, String> params = new HashMap<String, String>();
try {
params.put("name", URLEncoder.encode(name, "UTF-8"));
params.put("phone", phone);
return sendgetrequest(path, params);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "提交失败";
}
get_save（）
2.提交参数
private static String sendgetrequest(String path, Map<String, String> params)
throws Exception { // path="http://192.168.0.117/testxml/web.php?name=xx&phone=xx";
StringBuilder url = new StringBuilder(path);
url.append("?");
for (Map.Entry<String, String> entry : params.entrySet()) {
url.append(entry.getKey()).append("=");
url.append(entry.getValue()).append("&");
}
url.deleteCharAt(url.length() - 1);
URL url1 = new URL(url.toString());
HttpURLConnection conn = (HttpURLConnection) url1.openConnection();
conn.setConnectTimeout(5000);
conn.setRequestMethod("GET");
if (conn.getResponseCode() == 200) {
InputStream instream = conn.getInputStream();
ByteArrayOutputStream outstream = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
while (instream.read(buffer) != -1) {
outstream.write(buffer);
}
instream.close();
return outstream.toString().trim(); }
return "连接失败";
}
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
public static String post_save(String name, String phone) {
/**
* 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
* 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
*/
String path = "http://192.168.0.117/testxml/web.php";
Map<String, String> params = new HashMap<String, String>();
try {
params.put("name", URLEncoder.encode(name, "UTF-8"));
params.put("phone", phone);
return sendpostrequest(path, params);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "提交失败";
}
post_save
2.提交参数
private static String sendpostrequest(String path,
Map<String, String> params) throws Exception {
// name=xx&phone=xx
StringBuilder data = new StringBuilder();
if (params != null && !params.isEmpty()) {
for (Map.Entry<String, String> entry : params.entrySet()) {
data.append(entry.getKey()).append("=");
data.append(entry.getValue()).append("&");
}
data.deleteCharAt(data.length() - 1);
}
byte[] entiy = data.toString().getBytes(); // 生成实体数据
URL url = new URL(path);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(5000);
conn.setRequestMethod("POST");
conn.setDoOutput(true);// 允许对外输出数据
conn.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
conn.setRequestProperty("Content-Length", String.valueOf(entiy.length));
OutputStream outstream = conn.getOutputStream();
outstream.write(entiy);
if (conn.getResponseCode() == 200) {
InputStream instream = conn.getInputStream();
ByteArrayOutputStream byteoutstream = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
while (instream.read(buffer) != -1) {
byteoutstream.write(buffer);
}
instream.close();
return byteoutstream.toString().trim();
}
return "提交失败";
}
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
public static String httpclient_postsave(String name, String phone) {
/**
* 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
* 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
*/
String path = "http://192.168.0.117/testxml/web.php";
Map<String, String> params = new HashMap<String, String>();
try {
params.put("name", name);
params.put("phone", phone);
return sendhttpclient_postrequest(path, params);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "提交失败";
}
httpclient_postsave
2.提交参数
private static String sendhttpclient_postrequest(String path,Map<String, String> params) {
List<NameValuePair> pairs = new ArrayList<NameValuePair>();
for (Map.Entry<String, String> entry : params.entrySet()) {
pairs.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
}
try {
UrlEncodedFormEntity entity=new UrlEncodedFormEntity(pairs,"UTF-8");
HttpPost httpost=new HttpPost(path);
httpost.setEntity(entity);
HttpClient client=new DefaultHttpClient();
HttpResponse response= client.execute(httpost);
if(response.getStatusLine().getStatusCode()==200){
return EntityUtils.toString(response.getEntity(), "utf-8");
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
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
public static String httpclient_getsave(String name, String phone) {
/**
* 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
* 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

Map<String, String> params = new HashMap<String, String>();
try {
params.put("name", name);
params.put("phone", phone);
return sendhttpclient_getrequest(path, params);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return "提交失败";
}
httpclient_getsave
2.提交参数
private static String sendhttpclient_getrequest(String path,Map<String, String> map_params) {
List<BasicNameValuePair> params = new ArrayList<BasicNameValuePair>();
for (Map.Entry<String, String> entry : map_params.entrySet()) {
params.add(new BasicNameValuePair(entry.getKey(), entry.getValue()));
}
String param=URLEncodedUtils.format(params, "UTF-8");
HttpGet getmethod=new HttpGet(path+"?"+param);
HttpClient httpclient=new DefaultHttpClient();
try {
HttpResponse response=httpclient.execute(getmethod);
if(response.getStatusLine().getStatusCode()==200){
return EntityUtils.toString(response.getEntity(), "utf-8");
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
