Question

第一个请求正常执行，但相同的第二个请求返回错误400。从浏览器，此请求执行完整，通常多次。这很奇怪。也许，我不懂AsyncTask。这是请求类：

private  class LoginTask extends AsyncTask<Void,Void,String>{

@Override
protected String doInBackground(Void... voids) {
    RestTemplate template = new RestTemplate();
    template.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
    lgn = (EditText)findViewById(R.id.login) ;
    pass = (EditText)findViewById(R.id.password) ;

    return template.getForObject(Constants.URL.HOST+"login?login="+lgn.getText()+"&pass="+pass.getText(), String.class);
}

@Override
protected void onPostExecute(String str) {
  String result = (str.substring(1,str.length()-1)).trim();
        TextView rView = (TextView)findViewById(R.id.resView);
        rView.setText(result);
        if (result.equals("user")){
            global gl  = (global) LoginActivity.this.getApplication();
            gl.setLogin(lgn.getText().toString());
            Intent intent = new Intent(LoginActivity.this, UsersActionActivity.class);
            startActivity(intent);
        }
}

}

从android studio记录错误：

服务器代码：

@RestController
public class LoginController {

@Autowired
private AccountRepository accRep;

@RequestMapping(value = "/login", method = RequestMethod.GET)
@ResponseBody
public String loginQuery(@RequestParam (value ="login",required = true,defaultValue = "") String lgn,@RequestParam (value ="pass",required = true,defaultValue = "") String pass){
    String targetLogin = lgn.trim();
    String targetPass = pass.trim();

    String result = "none";

    List<Account> list = accRep.findAll();
    for (Account acc:list) {
        if (acc.getLogin().equals(targetLogin) && acc.getPassword().equals(targetPass)){
            result = acc.getAccountType();
        }
    }
    return  result;
}}

从android-application到服务器的第二个请求返回错误400（错误请求）
