网络请求（HttpUrlConnection/HttpClient）

httpurlconnection

get方式请求

URL url=new URL(params[0]);
HttpURLConnection connection=(HttpURLConnection) url.openConnection();
if(connection.getResponseCode()==200){
InputStream is=connection.getInputstream();
//调用自定义的json解析的工具类
String json=jiesonutils.getjson(is);
return
}

post

URL url=new URL("https://tcc.taobao.com/cc/json/mobile_tel_segment.htm");
HttpURLConnection connection=(HttpURLConnection) url.openConnection();

connection.setRequestMethod("POST");
//设置参数
connection.setDoOutput(true);//是否向服务器写参数
StringBuffer sb=new StringBuffer();
sb.append("tel=").append(et.getText().toString());
//写参数，写字节数组（吧参数内容转为字节数组）
byte[] be=sb.toString().getBytes();
connection.getOutputStream().write(be);

if(connection.getResponseCode()==200){
InputStream is=connection.getInputStream();
byte[] b=new byte[1024];
ByteArrayOutputStream bo=new ByteArrayOutputStream();
int length=0;
while((length=is.read(b))!=-1){
bo.write(b, 0, length);
}
String st=bo.toString("gbk");
String string=st.substring(st.indexOf("{"));
System.out.println(string);
jiexi(string);
}

HttpClient

get

//客户端请求
HttpClient client=new DefaultHttpClient();
//请求方式
HttpGet get=new HttpGet(params[0]);
//执行get请求，获得相应数据
HttpResponse response=client.execute(get);
if(response.getStatusLine().getStatusCode()==200){
InputStream is=response.getEntity().getContent();
//tojsonutils自定义的解析json的工具类
return tojsonutils.getjson(is);
}

Post

//定义一个请求客户端对象
HttpClient client=new DefaultHttpClient();
//定义post请求
HttpPost httpPost=new HttpPost(path);
//创建存放键值对的集合
List<BasicNameValuePair> parameters=new ArrayList<BasicNameValuePair>() ;
parameters.add(new BasicNameValuePair("info", et.getText().toString()));
parameters.add(new BasicNameValuePair("key", "65e2651ed3d6c03fb7172df8059578b8"));
//创建一个通过url编码过的表单对象
HttpEntity entity=new UrlEncodedFormEntity(parameters, "utf-8");
//设置请求的实体
httpPost.setEntity(entity);
//执行post请求获取对象
HttpResponse response = client.execute(httpPost);
if(response.getStatusLine().getStatusCode()==200){
InputStream is=response.getEntity().getContent();
String data=httputils.parseStream(is);
System.out.println(data);
Gson gson=new Gson();
bean be=gson.fromJson(data, bean.class);
list.add(be.result);

for(Result1 r:list){
str=r.text;
System.out.println("!!!!!!!!!!!!!!"+str);
}
runOnUiThread(new Runnable() {

@Override
public void run() {
// TODO Auto-generated method stub
tv.setText(str);
}
});
