Question

我必须做一个http帖子来获取一个令牌，这将授予我使用我的应用程序的权限。方法（obtieneToken）将此标记获取到另一个方法旁边的Asyntask类中。从另一个没有异步的类调用此方法，该类从App活动调用。当我的函数到达httpClient.execute（post）时，索引转到异常。我比较了我的应用程序与我的Web应用程序，Web应用程序运行良好。下一步是使用Wireshark捕获并且...当我执行我的应用程序时，我的wlan界面没有收到来自应用程序的任何请求。哪个可能是问题？这是代码：

public class ObtencionDatosUsuario extends AsyncTask<Integer, Integer, Boolean> {


protected static User obtieneDatos(String url, String aut) {
    // TODO Auto-generated method stub
    HttpClient httpClient = new DefaultHttpClient();
    HttpGet del = new HttpGet(url);// Se obtienen

                                                            // usuario

    String conectionValue;
    String codificada= Base64.encodeToString(aut.getBytes(), 0);
    String coded= codificada.replace("\n", "");
    System.out.println("nombre:clave= "+aut+" codificado es= "+coded);
    post.setHeader("content-type", "application/json");
    post.setHeader("Authorization", "Basic "+coded);
    try {
        HttpResponse resp = httpClient.execute(post);//Genera una excepcion 
        InputStream is= resp.getEntity().getContent();
        if((code=resp.getStatusLine().getStatusCode())!=200){
            token.setAuthToken("0");


        }else{
        token= (AuthToken) HalUnmarshaller.unmarshal(is, AuthToken.class);
        System.out.println("Token recibido en obtencion: "+ token);
        }
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (Exception e) {//Excepcion lanzad a por el post
        // TODO Auto-generated catch block
        e.printStackTrace(); 
    }

    return token;
}
@Override
protected Boolean doInBackground(Integer... params) {
    // TODO Auto-generated method stub
    return null;
}

}

这是包含异步方法的调用者的类：

public class ObtieneRecursos {
static String ip= "192.168.0.15";
public static User obtieneDatosUsuario(String aut, String who){
    //Peticion get a /users/:id
    String url= "http://"+ip+":8080/api/users/"+who;
    User usuario= new User();
    usuario= ObtencionDatosUsuario.obtieneDatos(url,aut);

    return usuario;
}
public static AuthToken obtieneTokenMe(String nombre, String clave){
    String url= "http://"+ip+":8080/api/auth-tokens/";
    AuthToken token= new AuthToken();
    token= ObtencionDatosUsuario.obtieneToken(nombre, clave, url);
    return token;
   }
}

非常感谢。

编辑2：现在我有从普通类调用的doInBackground方法中的代码：

public class ObtencionTokenUsuario extends AsyncTask<String, Integer, AuthToken> {

@Override
protected AuthToken doInBackground(String... datos) {
    // TODO Auto-generated method stub
            AuthToken token= new AuthToken();
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost post = new HttpPost(datos[2]);// Solicitud token
            int code;
            String aut=datos[0]+":"+datos[1];
            String conectionValue;
            String codificada= Base64.encodeToString(aut.getBytes(), 0);
            String coded= codificada.replace("\n", "");
            System.out.println("nombre:clave= "+aut+" codificado es= "+coded);
            post.setHeader("content-type", "application/json");
            post.setHeader("Authorization", "Basic "+coded);
            try {
                HttpResponse resp = httpClient.execute(post);//Genera una excepcion 
                InputStream is= resp.getEntity().getContent();
                if((code=resp.getStatusLine().getStatusCode())!=200){
                    token.setAuthToken("0");


                }else{
                token= (AuthToken) HalUnmarshaller.unmarshal(is, AuthToken.class);
                System.out.println("Token recibido en obtencion: "+ token);
                }
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {

                e.printStackTrace(); 
            }

            return token;
}

}

上课：

public class ObtieneRecursos{
public static AuthToken obtieneTokenMe(String nombre, String clave){
    String url= "http://"+ip+":8080/api/auth-tokens/";
    String[] params= new String[3];
    params[0]=nombre;
    params[1]=clave;
    params[2]=url;
    System.out.println("nombre = "+params[0]);
    System.out.println("clave = "+params[1]);
    System.out.println("url = "+params[2]);
    AuthToken token= new AuthToken();
    ObtencionTokenUsuario du= new ObtencionTokenUsuario();
    token=du.doInBackground(params);
    return token;
}
}

Answer 1

解决。问题出在HttpPost上，它收到的是String而不是URI。

Android方法不执行httppost请求
