我一直在嘗試使用具有JSON響應的GET方法來訪問webservice。通過android但拋出連接拒絕異常。我能夠在瀏覽器上打開URL並獲得響應，但獲取響應需要大約30秒的時間。當我運行我的應用程序時，它等待響應並拋出連接拒絕異常。請幫忙。HttpHostConnectException：連接被拒絕
Login.java（其由OnClick方法的）
class Login{
login.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
pro.setVisibility(View.VISIBLE);
new ExecuteTask().execute();
/* do{
pro.setVisibility(View.VISIBLE);
}while (response=resp())*/
/* if(response.contains("name")){
startActivity(new Intent(Login.this,Tab.class));
overridePendingTransition(R.anim.enter, R.anim.exit);
}
else if(response.contains("errorMessages")){
showPopUp();
}
else if(response.contains("<html>")||response.contains("site can't be reached")){
showerrorPopUp();
}
else{
showerrorPopUp();
}*/
}
});
異步任務 它調用RESP（）方法
public class ExecuteTask extends AsyncTask<String,Integer,String>{
@Override
protected String doInBackground(String... params) {
System.out.println("into async task");
String res=resp();
System.out.println("into execute task"+ res);
return res;
}
@Override
protected void onPostExecute(String result) {
pro.setVisibility(View.GONE);
//progess_msz.setVisibility(View.GONE);
}
}
RESP（）方法： 這個我thod由Http連接代碼組成 public String resp（）{0} 0 0 0 0 0 0 0 0 0 0 0 0 0 System.out.println（「resp strt」）;
System.out.println("into resp");
HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(append(URL));
try {
HttpEntity httpEntity = httpClient.execute(httpGet).getEntity();
if (httpEntity != null) {
InputStream inputStream = httpEntity.getContent();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
final StringBuilder stringBuilder = new StringBuilder();
String cen = null;
while ((cen = bufferedReader.readLine()) != null) {
/* Intent intent=new Intent(Login.this,MainActivity.class);
startActivity(intent);*/
stringBuilder.append(cen + "n");
}
inputStream.close();
resp = stringBuilder.toString();
/*text.setText(resp);*/
System.out.println("response" + resp);
}
} catch (ClientProtocolException e) {
Toast.makeText(Login.this, e.toString(), Toast.LENGTH_LONG);
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(Login.this, e.toString(), Toast.LENGTH_LONG);
}
System.out.println("resp end");
return resp;
}
append（）方法
public String append(String url){
url+=userName.getText().toString()+"/"+ password.getText().toString();
System.out.println("username"+userName.getText().toString());
return url;
}
