android - 如何在 Retrofit2 api 调用中调用 JSONObject？

问题描述

示例：我的输入是

{
  "company_id": 1,
  "customer_id": 1,
  "items": [
    {
      "service_id": "1",
      "service_description": "description here",
      "service_quantity": 1,
      "service_uom": "number",
      "service_price": "10000",
      "service_total": "10000",
      "service_taxid": 1,
      "service_taxvalue": "10"
    },
    {
      "service_id": "2",
      "service_description": "description here",
      "service_quantity": 1,
      "service_uom": "number",
      "service_price": "10000",
      "service_total": "10000",
      "service_taxid": 1,
      "service_taxvalue": "10"
    }
  ]
}

我声明如下：API Call-

@FormUrlEncoded
@POST("URL")
Observable <SampleResponse> generateInvoice(@Field("company_id") Integer companyId, @Field("customer_id") Integer customer_id, @Field("items") JSONArray params);

宣言：

JSONObject service1 = new JSONObject();
try {
    service1.put("service_id", id);
    service1.put("service_description", Desc);
    service1.put("service_quantity", Integer.valueOf(Qty));
    service1.put("service_uom", "number");
    service1.put("service_price", Amt);
    service1.put("service_total", GAmt);
    service1.put("service_taxid", 1);
    service1.put("service_taxvalue", 5);
    Log.d("jsonobject created", "" + service1);
} catch (JSONException e) {
    e.printStackTrace();
}

JSONArray array = new JSONArray().put(service1);
presenter.generateInvoice(1,"company123",array);

后端错误：'{\"service_id\":3,\"service_description\":\"Mobile Application\",\"service_quantity\":5,\"service_uom\":\"number\",\"service_price \":\"650\",\"service_total\":\"3640\",\"service_taxid\":1,\"service_taxvalue\":5}';

斜线不在 api 输入调用中，而是在后端看到。这会导致 http 500 错误。我尝试添加@Body RequestClass 并删除@FormUrlEncoded，但这不起作用，因为它有@Field。或者我们是否需要 2 个 api 调用来实现这一点？

解决方案

已解决的问题 对于给定的输入，我们应该创建一个 json 对象并使用 @Body RequestBody 发布数据。无需@Field。下面是用于制作一个包含所有数据的单个 json 对象的代码-

JSONArray itemsArray = new JSONArray();
                    JSONObject service1 = new JSONObject();
                    JSONObject finalobject = new JSONObject();

                    try {
                        service1.put("service_id", id);
                        service1.put("service_description", Desc);
                        service1.put("service_quantity", Integer.valueOf(Qty));
                        service1.put("service_uom", "number");
                        service1.put("service_price", Amt);
                        service1.put("service_total", GAmt);
                        service1.put("service_taxid", 1);
                        service1.put("service_taxvalue", 5);

                        finalobject.put("company_id",companyid);
                        finalobject.put("customer_id",CUST_ID);
                        itemsArray.put(service1);
                        finalobject.put("items",itemsArray);

                    } catch (JSONException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }

finalobject 将给出 json 对象
