AsyncHttp請求Post請求格式

這種是可以自定義post的參數的格式的，一般使用json，詳情請見（http://stackoverflow.com/questions/26842090/asynchttpclient-passed-contenttype-will-be-ignored-because-httpentity-sets-cont）舉例說明

                AsyncHttpClient client = new AsyncHttpClient();
                final String url = Utils.baseUrl+"regist.html";
                JSONObject jsonObject = new JSONObject();
                try {
                    jsonObject.put("username",etPhoneNumber.getText());
                    jsonObject.put("password",etPassword.getText());
                } catch (JSONException e) {
                    e.printStackTrace();
                }
                ByteArrayEntity entity = null;
                try {
                    entity = new ByteArrayEntity(jsonObject.toString().getBytes("UTF-8"));
                    entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
                } catch (UnsupportedEncodingException e) {
                    e.printStackTrace();
                }

                client.post(mContext,url,entity,"application/json",new JsonHttpResponseHandler(){
                    @Override
                    public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
                        super.onSuccess(statusCode, headers, response);
                        Log.e("rs",response.toString());
                    }

                    @Override
                    public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject errorResponse) {
                        super.onFailure(statusCode, headers, throwable, errorResponse);
                    }
                });

另一種是使用

post(java.lang.String url, RequestParams params, ResponseHandlerInterface responseHandler)

這個post方法，這種是就是常規的提價表單格式，齊參數的格式爲username=yzk&password=yzk這種。使用舉例

 final RequestParams params = new RequestParams();
                params.put("username",etPhoneNumber.getText());
                params.put("password",etPassword.getText());
                client.post(url,params,new JsonHttpResponseHandler(){
                    @Override
                    public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
                        super.onSuccess(statusCode, headers, response);
                        try {
                            Log.e("rs",response.getString("status"));
                            if(response.getString("status").equals("0")){
                                user = User.getInsstance();
                                user.setIsOnline(true);
                                user.setToken(response.getString("token"));
                                user.setId(etPhoneNumber.getText().toString());
                                Toast.makeText(mContext,"註冊成功",Toast.LENGTH_LONG).show();
                                mContext.finish();
                            }else{
                                Toast.makeText(mContext,"改用已註冊",Toast.LENGTH_LONG).show();
                            }
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                    @Override
                    public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject errorResponse) {
                        super.onFailure(statusCode, headers, throwable, errorResponse);
                        Toast.makeText(mContext,"網絡錯誤",Toast.LENGTH_LONG).show();
                    }
