java中get请求和post请求分别请求的对象类型是什么，什么不一样
1. get 是从服务器上获取数据，post 是向服务器传送数据。 get 请求返回 request - URI 所指出的任意信息。
Post 请求用来发送电子邮件、新闻或发送能由交互用户填写的表格。这是唯一需要在请求中发送body的请求。使用Post请求时需要在报文首部 Content - Length 字段中指出body的长度。
2. get 是把参数数据队列加到提交表单的ACTION属性所指的URL中，值和表单内各个字段一一对应，在URL中可以看到。post是通过HTTP post机制，将表单内各个字段与其内容放置在HTML HEADER内一起传送到ACTION属性所指的URL地址，用户看不到这个过程。
3. 对于 get 方式，服务器端用Request.QueryString获取变量的值，对于 post 方式，服务器端用Request.Form获取提交的数据。
4. get 传送的数据量较小，不能大于2KB。post 传送的数据量较大，一般被默认为不受限制。但理论上，IIS4中最大量为80KB，IIS5中为100KB。 用IIS过滤器的只接受get参数，所以一般大型搜索引擎都是用get方式。
5. get 安全性非常低，post 安全性相对较高。如果这些数据是中文数据而且是非敏感数据，那么使用 get；如果用户输入的数据不是中文字符而且包含敏感数据，那么还是使用 post 为好。
java中怎样用post，get，put请求
java中用post，get，put请求方法：
public static String javaHttpGet(String url,String charSet){
String resultData = null;
try {
URL pathUrl = new URL(url); //创建一个URL对象
HttpURLConnection urlConnect = (HttpURLConnection) pathUrl.openConnection(); //打开一个HttpURLConnection连接
urlConnect.setConnectTimeout(30000); // 设置连接超时时间
urlConnect.connect();
if (urlConnect.getResponseCode() == 200) { //请求成功
resultData = readInputStream(urlConnect.getInputStream(), charSet);
}
} catch (MalformedURLException e) {
LogL.getInstance().getLog().error("URL出错！", e);
} catch (IOException e) {
LogL.getInstance().getLog().error("读取数据流出错！", e);
}
return resultData;
}
public static String javaHttpPost(String url,MapString,Object map,String charSet){
String resultData=null;
StringBuffer params = new StringBuffer();
try {
IteratorEntryString, Object ir = map.entrySet().iterator();
while (ir.hasNext()) {
Map.EntryString, Object entry = (Map.EntryString, Object) ir.next();
params.append(URLEncoder.encode(entry.getKey(),charSet) + "=" + URLEncoder.encode(entry.getValue().toString(), charSet) + "");
}
byte[] postData = params.deleteCharAt(params.length()).toString().getBytes();
URL pathUrl = new URL(url); //创建一个URL对象
HttpURLConnection urlConnect = (HttpURLConnection) pathUrl.openConnection();
urlConnect.setConnectTimeout(30000); // 设置连接超时时间
urlConnect.setDoOutput(true); //post请求必须设置允许输出
urlConnect.setUseCaches(false); //post请求不能使用缓存
urlConnect.setRequestMethod("POST"); //设置post方式请求
urlConnect.setInstanceFollowRedirects(true);
urlConnect.setRequestProperty("Content-Type","application/x-www-form-urlencoded; charset="+charSet);// 配置请求Content-Type
urlConnect.connect(); // 开始连接
DataOutputStream dos = new DataOutputStream(urlConnect.getOutputStream()); // 发送请求参数
dos.write(postData);
dos.flush();
dos.close();
if (urlConnect.getResponseCode() == 200) { //请求成功
resultData = readInputStream(urlConnect.getInputStream(),charSet);
}
} catch (MalformedURLException e) {
LogL.getInstance().getLog().error("URL出错！", e);
} catch (IOException e) {
LogL.getInstance().getLog().error("读取数据流出错！", e);
} catch (Exception e) {
LogL.getInstance().getLog().error("POST出错！", e);
}
return resultData;
}
JAVA中Get和Post请求的区别收集整理
Get：是以实体的方式得到由请求URI所指定资源的信息，如果请求URI只是一个数据产生过程，那么最终要在响应实体中返回的是处理过程的结果所指向的资源，而不是处理过程的描述。
Post：用来向目的服务器发出请求，要求它接受被附在请求后的实体，并把它当作请求队列中请求URI所指定资源的附加新子项，Post被设计成用统一的方法实现下列功能：
1：对现有资源的解释
2：向电子公告栏、新闻组、邮件列表或类似讨论组发信息。
3：提交数据块
4：通过附加操作来扩展数据库
从上面描述可以看出，Get是向服务器发索取数据的一种请求；而Post是向服务器提交数据的一种请求，要提交的数据位于信息头后面的实体中。
