我想在改造中在身体中传递以下请求。我的问题是如上所示正在使用的json数组。任何人都可以告诉如何在retrofit中传递此请求。以上是我要通过的json请求在改造体中

Answer 1

使用此模型类构建请求主体，您应该根据需要使用getter和setter。

public class PaymentModel {
@SerializedName("intent")
public String intent;
@SerializedName("redirect_urls")
public RedirectUrls redirectUrls;
@SerializedName("payer")
public Payer payer;
@SerializedName("transactions")
public List<Transactions> transactions;

public static class RedirectUrls {
    @SerializedName("return_url")
    public String returnUrl;
    @SerializedName("cancel_url")
    public String cancelUrl;
}

public static class Payer {
    @SerializedName("payment_method")
    public String paymentMethod;
}

public static class Amount {
    @SerializedName("total")
    public String total;
    @SerializedName("currency")
    public String currency;
}

public static class Transactions {
    @SerializedName("amount")
    public Amount amount;
}
}

您还应该添加此依赖项;

 compile 'com.google.code.gson:gson:2.8.0'

然后在改装请求中;

Call<ResponseBody> PaymentRequest(@Body PaymentModel model);

要查看您已构建的完整模型类，请使用;

Gson gson=new Gson();
String modelClass =gson.toJson(model);

Answer 2

首先从你请求结果中创建一个JSONObject。例如：

   JSONObject jObject = new JSONObject(string request result)

然后从jObject使用JSONArray，getString，getInt和....解析数据。

请看这里：Android, Parsing JSON object

编辑：设为POJO：

例如，您的POJO是：

      public class Information {
         public String intent;
         public String return_url;
         public String cancel_url;
      }

并将json data设置为您的POJO：

       try {
           JSONObject jObject = new JSONObject(string request result)

           Information info=new Information;
           info.intent=jObject.getString("intent");

           JSONObject jObject = new JSONObject(jObject.getString("redirect_urls"))
           info.return_url=jObject.getString("return_url");
           info.cancel_url=jObject.getString("cancel_url");

       } catch (JSONException e) {}

Answer 3

创建表示json（POJO）的模型对象。改造将使用Gson进行序列化。使用正文表示法在改造界面中定义Post方法：MyModule::Utils::Slug.slug_it(attrs[:name], true)

Answer 4

像这样创建POJO类： -

 public class PaypalObject {
        @SerializedName("transactions")
        @Expose
        private ArrayList<Transaction> transaction;
    }
   public class Transaction {
        @SerializedName("amount")
        @Expose
        private Amount amount;
    }

    public class Amount {
        @SerializedName("total")
        @Expose
        private String total;

        @SerializedName("currency")
        @Expose
        private String currency;
    }

将PaypalObject传递给@Body PaypalObject paypalObject

Answer 5

public class MyPayment {

private String intent;
private MyRedirect redirect_urls;
private MyPayer payer;
private List<MyTrans> transactions;

public MyPayment(String intent, MyRedirect redirect_urls, MyPayer payer, List<MyTrans> transactions) {
    this.intent = intent;
    this.redirect_urls = redirect_urls;
    this.payer = payer;
    this.transactions = transactions;
}

}

公共类MyRedirect {

private String return_url;
private String cancel_url;

public MyRedirect(String return_url, String cancel_url) {
    this.return_url = return_url;
    this.cancel_url = cancel_url;
}

}

公共类MyPayer { private String payment_method;

public MyPayer(String payment_method) {
    this.payment_method = payment_method;
}

}

公共类MyTrans { 私人MyAmount金额;

public MyTrans(MyAmount amount) {
    this.amount = amount;
}

}

公共类MyAmount {

private String total;
private String currency;

public MyAmount(String total, String currency) {
    this.total = total;
    this.currency = currency;
}

}

    MyRedirect redi = new MyRedirect("http://example.com/your_redirect_url.html","http://example.com/your_cancel_url.html");
    MyPayer mypay = new MyPayer("paypal");
    List<MyTrans> transs = new ArrayList<MyTrans>();


    MyAmount myamo = new MyAmount("6.70","USD");
    MyTrans transact = new MyTrans(myamo);
    transs.add(transact);
    MyPayment mypayment = new MyPayment("sale",redi,mypay,transs);
