Android应用开发中,会经常要提交数据到服务器和从服务器得到数据,本文主要是给出了利用http协议采用HttpClient方式向服务器提交数据的方法。
代码比较简单,这里不去过多的阐述,直接看代码。

* 本类封装了Android中向web服务器提交数据的两种方式四种方法 |
005 |
public class SubmitDataByHttpClientAndOrdinaryWay { |
009 |
* @param map 传递进来的数据,以map的形式进行了封装 |
010 |
* @param path 要求服务器servlet的地址 |
011 |
* @return 返回的boolean类型的参数 |
014 |
public Boolean submitDataByDoGet(Map<String, String> map, String path) throwsException { |
016 |
StringBuilder sb = new StringBuilder(path); |
018 |
for (Map.Entry<String, String> entry : map.entrySet()) { |
019 |
sb.append(entry.getKey()).append("=").append(entry.getValue()); |
022 |
sb.deleteCharAt(sb.length() - 1); |
023 |
String str = sb.toString(); |
024 |
System.out.println(str); |
025 |
URL Url = new URL(str); |
026 |
HttpURLConnection HttpConn = (HttpURLConnection) Url.openConnection(); |
027 |
HttpConn.setRequestMethod("GET"); |
028 |
HttpConn.setReadTimeout(5000); |
030 |
if (HttpConn.getResponseCode() == HttpURLConnection.HTTP_OK) { |
038 |
* @param map 传递进来的数据,以map的形式进行了封装 |
039 |
* @param path 要求服务器servlet的地址 |
040 |
* @return 返回的boolean类型的参数 |
043 |
public Boolean submitDataByDoPost(Map<String, String> map, String path) throwsException { |
045 |
URL Url = new URL(path); |
047 |
StringBuilder sb = new StringBuilder(); |
049 |
for (Map.Entry<String, String> entry : map.entrySet()) { |
050 |
sb.append(entry.getKey()).append("=").append(entry.getValue()); |
053 |
sb.deleteCharAt(sb.length() - 1); |
054 |
String str = sb.toString(); |
056 |
HttpURLConnection HttpConn = (HttpURLConnection) Url.openConnection(); |
057 |
HttpConn.setRequestMethod("POST"); |
058 |
HttpConn.setReadTimeout(5000); |
059 |
HttpConn.setDoOutput(true); |
060 |
HttpConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); |
061 |
HttpConn.setRequestProperty("Content-Length", String.valueOf(str.getBytes().length)); |
062 |
OutputStream os = HttpConn.getOutputStream(); |
063 |
os.write(str.getBytes()); |
064 |
if (HttpConn.getResponseCode() == HttpURLConnection.HTTP_OK) { |
071 |
* 以HttpClient的DoGet方式向服务器发送请数据 |
072 |
* @param map 传递进来的数据,以map的形式进行了封装 |
073 |
* @param path 要求服务器servlet的地址 |
074 |
* @return 返回的boolean类型的参数 |
