Question

网址示例= http://webapi.example.com/api/order?data= {... list [{...}，{...}]}

 GsonRequest request = new GsonRequest<OrderResponse>("URL example", null,
            OrderResponse.class, null, new Response.Listener<OrderResponse>() {
        @Override
        public void onResponse(OrderResponse response) {
            if (response.isSuccess()) {
                //sendNotification();
            } else {
                Toast.makeText(DeliveryManagementActivity.this, "Error in Server", Toast.LENGTH_SHORT).show();
            }
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.e("Error: " + error.getMessage());
        }
    });

对于上面的代码，我收到400错误。

GsonRequest request = new GsonRequest<OrderResponse>(UrlConstants.SEND_ORDERS_URL, getParams(),
            OrderResponse.class, header, new Response.Listener<OrderResponse>() {
        @Override
        public void onResponse(OrderResponse response) {
            if (response.isSuccess()) {
                sendNotification();
            } else {
                Toast.makeText(DeliveryManagementActivity.this, "Error in Server", Toast.LENGTH_SHORT).show();
            }
            hideLoader();
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            error.printStackTrace();
            VolleyLog.e("Error: " + error.getMessage());
            Toast.makeText(DeliveryManagementActivity.this, "Error " + error.getMessage(), Toast.LENGTH_SHORT).show();
            hideLoader();
        }
    });

public Map<String, String> getHeaders() throws AuthFailureError {
    HashMap<String, String> headers = new HashMap<String, String>();
    headers.put("Content-Type", "application/json");
    return headers;
}

private Map<String, String> getParams() {
    Map<String, String> params = new HashMap<String, String>();
    params.put("orderData", requestData.getOrderRequest(requestData));

    return params;
}

对于上述情况，我总是从服务器得到错误的错误响应。我从第一个请求方法复制了请求，并使用浏览器URL来访问API。它运作良好。

编辑：

更改为第二种方式后，请求如下所示。

网址 = www.url.com/addOrder.php？

params = {“orderData”：“{\”deliveryTime \“：\”2017-12-10 01:13:00 \“，\”orderDetail \“：[{\” courseId \ “：\” 1 \” \ “foodQuantity \”：\ “2 \” \ “offer_id \”：\ “ - 1 \” \ “类型\”：\ “1 \”}]，\ “用户ID \”：\ “7 \”，\ “用户位置\”：\ “17 \”}“}

orderData 也在json中解析并缺少 = 。这是问题所在。问题顶部的网址是实际的，并且正在运行。

Answer 1

查询参数名称 orderData ？ url中使用的查询参数是 data 。其他代码看起来还不错。

Answer 2

对网址进行编码后，问题就解决了。

 try {
        param = URLEncoder.encode("json", "utf-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }

String url = baseUrl + params;

 GsonRequest request = new GsonRequest<OrderResponse>(url, null,
        OrderResponse.class, null, new Response.Listener<OrderResponse>() {
    @Override
    public void onResponse(OrderResponse response) {
        if (response.isSuccess()) {
            //sendNotification();
        } else {
            Toast.makeText(DeliveryManagementActivity.this, "Error in Server", Toast.LENGTH_SHORT).show();
        }
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        VolleyLog.e("Error: " + error.getMessage());
    }
});

API URL无法在排球中工作并在浏览器网址中工作
