Question

我正在使用我的应用程序中的凌空库来处理Magento API。对于一个特定的API，响应会根据应用程序中完成的操作而发生变化。

以下是进行任何更改之前的响应：

[
  {
    "grand_total": 0,
    "subtotal": 7144,
    "shipping_amount": 0,
    "items_qty": 1,
    "items": [
      {
        "item_id": "1654",
        "price": 7144,
        "qty": 1,
        "name": "STYLUS ITEM"
      }
    ],
    "deductions": {
      "jss": null,
      "coupon": [  ],
      "gift_cards": [ ]
    }
  }
]

进行更改后，当我在POSTMAN中第二次调用API时，响应将更新为

[
  {
    "grand_total": 0,
    "subtotal": 7144,
    "shipping_amount": 0,
    "items_qty": 1,
    "items": [
      {
        "item_id": "1654",
        "price": 7144,
        "qty": 1,
        "name": "STYLUS ITEM"
      }
    ],
    "deductions": {
      "jss": {
        "method": "amount",
        "customer_id": 394,
        "schemes": [
          {
            "msno": 145,
            "group_code": "GLN",
            "company_code": "GWO",
            "amount": 3496,
            "scheme_id": 143
          }
        ]
      },
      "coupon": [],
      "gift_cards": [ ]
    }
  }
]

这是通过在magento会话中保留修改后的值来完成的，但是当使用android app进行第二次服务调用时，我无法获得更新后的响应。响应仍然是第一个。我知道排球库无法通过引用此链接来维护cookie。 Volley Library for cookies

这是我用来解析API响应的GsonRequest类。

public class GsonRequest<T> extends Request<T> {

    private static final String TAG = GsonRequest.class.getSimpleName();
    /**
     * Charset for request.
     */
    private static final String PROTOCOL_CHARSET = "utf-8";

    /**
     * Content type for request.
     */
    private static final String PROTOCOL_CONTENT_TYPE =
            String.format("application/json; charset=%s", PROTOCOL_CHARSET);

    private final Listener<T> mListener;

    private final String mRequestBody;

    private Gson mGson;
    private Class<T> mJavaClass;
    private Map<String, String> headers;

    public GsonRequest(int method, String url, Class<T> cls, Map<String, String> header, String requestBody, Listener<T> listener,
                       ErrorListener errorListener) {
        super(method, url, errorListener);
        mGson = new Gson();
        mJavaClass = cls;
        mListener = listener;
        headers = header;
        mRequestBody = requestBody;

    }

    @Override
    protected void deliverResponse(T response) {
        mListener.onResponse(response);
    }

    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        return headers;
    }

    @Override
    protected Response<T> parseNetworkResponse(NetworkResponse response) {
        try {
            int statusCode = response.statusCode;
            Log.v(TAG + " Status Code", String.valueOf(statusCode));
            String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
            T parsedGSON = mGson.fromJson(jsonString, mJavaClass);
            return Response.success(parsedGSON,
                    HttpHeaderParser.parseCacheHeaders(response));

        } catch (UnsupportedEncodingException e) {
            return Response.error(new ParseError(e));
        } catch (JsonSyntaxException je) {
            return Response.error(new ParseError(je));
        }
    }

    @Override
    public String getBodyContentType() {
        return PROTOCOL_CONTENT_TYPE;
    }

    @Override
    public byte[] getBody() {
        try {
            return mRequestBody == null ? null : mRequestBody.getBytes(PROTOCOL_CHARSET);
        } catch (UnsupportedEncodingException uee) {
            VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s",
                    mRequestBody, PROTOCOL_CHARSET);
            return null;
        }
    }

}

我正在按如下方式拨打服务电话：

GsonRequest gsonRequest = new GsonRequest<AmountDetailsResp[]>(Request.Method.POST, builder.toString(),
                AmountDetailsResp[].class, hashHeader, new Gson().toJson(amountDetailsReq), new Response.Listener<AmountDetailsResp[]>() {
            @Override
            public void onResponse(AmountDetailsResp[] responseArray) {
                fragment.stopProgressDialog();
                if (responseArray != null) {
                    for (int i = 0; i < responseArray.length; i++) {
                        AmountDetailsResp response = responseArray[i];
                        setCartTotalDetails(response.items.size(), response.subtotal, response.shipping_amount, response.grand_total);

                        fragment.getShippingDetailValue(response.items.size(), response.subtotal,
                                response.shipping_amount, response.grand_total,
                                fragment.checkedTextView.isChecked(), shippingAddressBean, billingAddressBean,
                                methodCode, carrierCode, addressId);
                    }

                }
            }
        },
                new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        fragment.stopProgressDialog();
                        Utility.showVolleyError(fragment.getContext(), TAG, error);
                    }
                });
        AppController.getInstance().addToRequestQueue(gsonRequest);

我想知道为启用cookie存储并在volley库中维护该会话而必须进行的更改，以便能够获得更新的响应。任何帮助是极大的赞赏。预先感谢。

Answer 1

Magento会话值存储为cookie。我无法获取这些值，因为默认情况下 volley库不接受并从服务器读取cookie 。我从答案Using cookies with Volley中找到了解决方案。请仔细阅读以便更好地理解。

排球库未在Android应用中获取Magento会话值
