不能在 Restassured 请求中将 Json 数组作为正文传递 - java.lang.IllegalStateException：不是 JSON 对象

Question

我试图在一个放心的请求中传递一个对象列表作为主体:

Transaction transaction1 = new Transaction();
Transaction transaction2 = new Transaction();
List<Transaction> transactionList = new ArrayList<Transaction>();
transaction1.setTransactionType= "TRANS";
transaction1.setAmmount=12;
transaction2.setTransactionType= "EXTR";
transaction2.setAmmount=15;
transactionList.add(transaction1);
transactionList.add(transaction2);
given().contentType(ContentType.JSON)
.body(transactionList).when()
.post(http://localhost:8085/transactions/batch);

但是当我发送请求时，我得到:

Not a JSON Object: [{"transactionType":"TRANS","amount":"12"}, {"transactionType":"EXTR","amount":"15"}]
java.lang.IllegalStateException: Not a JSON Object: [{"transactionType":"TRANS","amount":"12"}, {"transactionType":"EXTR","amount":"15"}]   at com.google.gson.JsonElement.getAsJsonObject(JsonElement.java:91)

我已经尝试了JSONArray jsonArray = new JSONArray(transactionList)，但没有成功，看起来像这样的请求:

2021-02-12 20:45:42,927 [Test worker] INFO  org.fpsautomation.loggerextension.LogFilter - Request details:
POST http://localhost:8085/transactions/batch 
Accept=*/*
Content-Type=application/json; charset=UTF-8
Params: {} 
Request body: {
"empty": false
}

Answer 1

因为transactionList是List的一个实例，而JSON需要key:value对，所以您需要使用Map来生成适当的有效负载。最简单的方法是:

Map<Object, Object> payload = new HashMap<>();
payload.put(transactionList, "");

这当然会让你的身体，但你应该根据你的需要来玩和适合它。
