我想通過retrofit2傳遞一個自定義對象，而我的問題是服務器是否自動將自定義對象寫入json或者是否必須爲此編寫一個php文件。與此同時，我成功發佈到服務器，但無法寫入json。在改造中傳遞自定義對象2
我的目標是將自定義對象寫入服務器，並將自定義對象的內容寫入json文件。
這是我改造阿比
public interface ApsaraCatalogAPI {
@GET("/apsaratrendz/data/apsara_json_document_v2.json")
Call<List<ApsaraCatalogModel>> getFeed();
@POST("/apsaratrendz/data/apsara_json_orders_document.json")
Call<Void> setOrder(@Body OrderModel orderModel);
}
這裏是我的調用API函數
@Override
public void onClick(View v) {
int total = 0;
if(v.getId()==R.id.fabButtonCart && cartlist.size()!=0)
{
// get details from shared preferences
OrderModel orderModel = new OrderModel();
orderModel.setDate(getDate());
orderModel.setName("ssdfs");
orderModel.setEmail("[email protected]");
orderModel.setNoofitems(String.valueOf(cartlist.size()));
orderModel.setOrderno("32335");
orderModel.setPhone("9896566444");
for(int i=0; i<cartlist.size();i++){
Productdetail pd = new Productdetail();
pd.getSellingprice(String.valueOf(cartlist.get(i).getSellingPrice()));
pd.getPid(cartlist.get(i).getEANCode());
total += cartlist.get(i).getSellingPrice();
orderModel.getProductdetails().add(pd);
}
//
// now go for insertion using retrofit
requestData(orderModel);
Toast.makeText(getApplicationContext(), "Total Price : Rs."+total+"/-", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getApplicationContext(), "Cart is Empty", Toast.LENGTH_LONG).show();
}
}
這裏是改造的API，我傳遞新創建的POJO類OrderModel我的服務請求。
import java.util.Map;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
public class OrderModel {
private String name;
private String email;
private String phone;
private String orderno;
private String date;
private String noofitems;
private List<Productdetail> productdetails = new ArrayList<Productdetail>();
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
/**
*
* @return
* The name
*/
public String getName() {
return name;
}
/**
*
* @param name
* The name
*/
public void setName(String name) {
this.name = name;
}
/**
*
* @return
* The email
*/
public String getEmail() {
return email;
}
/**
*
* @param email
* The email
*/
public void setEmail(String email) {
this.email = email;
}
/**
*
* @return
* The phone
*/
public String getPhone() {
return phone;
}
/**
*
* @param phone
* The phone
*/
public void setPhone(String phone) {
this.phone = phone;
}
/**
*
* @return
* The orderno
*/
public String getOrderno() {
return orderno;
}
/**
*
* @param orderno
* The orderno
*/
public void setOrderno(String orderno) {
this.orderno = orderno;
}
/**
*
* @return
* The date
*/
public String getDate() {
return date;
}
/**
*
* @param date
* The date
*/
public void setDate(String date) {
this.date = date;
}
/**
*
* @return
* The noofitems
*/
public String getNoofitems() {
return noofitems;
}
/**
*
* @param noofitems
* The noofitems
*/
public void setNoofitems(String noofitems) {
this.noofitems = noofitems;
}
/**
*
* @return
* The productdetails
*/
public List<Productdetail> getProductdetails() {
return productdetails;
}
/**
*
* @param productdetails
* The productdetails
*/
public void setProductdetails(List<Productdetail> productdetails) {
this.productdetails = productdetails;
}
public Map<String, Object> getAdditionalProperties() {
return this.additionalProperties;
}
public void setAdditionalProperty(String name, Object value) {
this.additionalProperties.put(name, value);
}
}
產品詳細類：
private void requestData(OrderModel orderModel) {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(ENDPOINT)
.addConverterFactory(GsonConverterFactory.create())
.build();
ApsaraCatalogAPI service = retrofit.create(ApsaraCatalogAPI.class);
Call<Void> call = service.setOrder(orderModel);
call.enqueue(new Callback<Void>() {
@Override
public void onResponse(Call<Void> call, Response<Void> response) {
if(response.isSuccessful()){
Log.d("InApi","Yipppie");
}
}
@Override
public void onFailure(Call<Void> call, Throwable t) {
Log.d("InApi","Kaboom");
}
});
}
我的POJO類下面給出
import java.util.HashMap;
import java.util.Map;
public class Productdetail {
private String pid;
private String sellingprice;
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
/**
*
* @return
* The pid
* @param s
*/
public String getPid(String s) {
return pid;
}
/**
*
* @param pid
* The pid
*/
public void setPid(String pid) {
this.pid = pid;
}
/**
*
* @return
* The sellingprice
* @param s
*/
public String getSellingprice(String s) {
return sellingprice;
}
/**
*
* @param sellingprice
* The sellingprice
*/
public void setSellingprice(String sellingprice) {
this.sellingprice = sellingprice;
}
public Map<String, Object> getAdditionalProperties() {
return this.additionalProperties;
}
public void setAdditionalProperty(String name, Object value) {
this.additionalProperties.put(name, value);
}
}
什麼是服務器的JSON響應？根據錯誤消息，您的API會返回一個對象列表，但您指定了一個對象。 – peitek
我不希望我的API返回任何東西（更新的問題），只是想寫我的POJO到JSON，所以我需要PHP文件來做到這一點，或者服務器是否處理這個？我對改造和PHP非常陌生.. –
從改造方面看，一切看起來都不錯。 – peitek
