使用 Unirest 和 Java 和 Selenium WebDriver 解析 Json

Question

我正在测试一个本地 api。 使用下面的代码，我得到了一个响应。 我需要从"returnMessage" 和"returnCode" 和"merchantOrderId" 获取数据，我已经尝试了很多方法，但都不能，请有人帮我吗？

API 测试代码：

@Test 
        public void Cod04Autorized() {


            HttpResponse<String> response = Unirest.post("http://localhost:8080/api/cielo/pagamentos/transacaoCompleta")
              .header("Content-Type", "application/json")
              .body("{\r\n\t\"merchantOrderId\": \"11234099\",\r\n\t\"client\": {\r\n\t\t\"name\": \"Joao das Neves Teste No Cap\"\r\n\t},\r\n\t\"payment\": {\r\n\t\t\"amount\": 10000,\r\n\t\t\"installments\": 1,\r\n\t\t\"capture\": false,\r\n\t\t\"card\": {\r\n\t\t\t\t\"cardNumber\": \"0000.0000.0000.0001\",\r\n\t\t\t\t\"holderName\": \"Joao das Neves\",\r\n\t\t\t\t\"expirationDate\": \"12/2030\",\r\n\t\t\t\t\"securityCode\": \"123\",\r\n\t\t\t\t\"brand\" : \"Visa\"\r\n\t\t}\r\n\t}\r\n}")
              .asString();


            Assert.assertEquals(200, response.getStatus());                 


            }

JSON 响应：

如果你只想获取returnMessage、returnCode和merchantOrderId这三个字段，使用Jayway JsonPath可以轻松完成。

Maven 依赖项

<dependency>
    <groupId>com.jayway.jsonpath</groupId>
    <artifactId>json-path</artifactId>
    <version>2.4.0</version>
</dependency>

代码 sn-p

DocumentContext jsonContext = JsonPath.parse(jsonResponse);
String returnMessage = jsonContext.read("$.content.payment.returnMessage");
String returnCode = jsonContext.read("$.content.payment.returnCode");
String merchantOrderId = jsonContext.read("$.content.merchantOrderId");
