REST Assured 67 - How To Assert Full Response JSON Body In Rest Assured?

REST Assured 系列汇总之 REST Assured 67 - How To Assert Full Response JSON Body In Rest Assured?

介绍

如果 response 是某种不变的或小量内容的，那我们就可以直接断言整个 response，就不用将 response 反序列化成某 Java objects，再提取一些值进行匹配断言。

本文我们来交接一下怎样断言整个 response。

前提条件

添加 rest assured 依赖库

<!-- REST Assured -->
<dependency>
   <groupId>io.rest-assured</groupId>
   <artifactId>rest-assured</artifactId>
   <version>4.4.0</version>
</dependency>

断言整个 response body

需要用到 Hamcrest Matchers 和 body() 方法，以 GoRest APIs 为例。注意这些例子可能会有些变化，因为是公用的 APIs，如果想尝试，请按最新的 API 调用结果为准做些适当的调整。

import org.hamcrest.Matchers;

import io.restassured.RestAssured;

public class AssertFullResponseBody {
    
    

    public static void main(String[] args) {
    
    

        RestAssured
                // Construct request
                .given()
                .log()
                .all()
                .baseUri("https://gorest.co.in/public-api/")
                .basePath("users/{id}")
                .pathParam("id", "2833")
                // Hit API
                .when()
                .get()
                .then()
                // Assert response
                .log()
                .all()
                .assertThat()
                // Pass full expected response body with Hamcrest matchers
                .body(Matchers.equalTo("{\"code\":200,\"meta\":null,\"data\":{\"id\":2833,\"name\":\"Kathline Villanveva\",\"email\":\"[email protected]\",\"gender\":\"male\",\"status\":\"inactive\"}}"));
    }

}

需要将期望的 JSON body 用工具格式 formatted JSON in to single line 转换成一行，传给 equalTo() 方法。如果不格式化一行，一些回车符号 (\r\n) 存在会影响验证。

输出：

    }
}

从外部文件断言整个 response body

将期望的 response body 存储在一个外部 JSON 文件:
在这里插入图片描述

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import org.hamcrest.Matchers;
import io.restassured.RestAssured;

public class AssertFullResponseBodyFromExternalFile {
    
    

    public static void main(String[] args) throws IOException {
    
    

        RestAssured
                // Construct request
                .given()
                .log()
                .all()
                .baseUri("https://gorest.co.in/public-api/")
                .basePath("users/{id}")
                .pathParam("id", "2833")
                // Hit API
                .when()
                .get()
                .then()
                // Assert response
                .log()
                .all()
                .assertThat()
                // Pass full expected response body with Hamcrest matchers
                .body(Matchers.equalTo(new String(Files.readAllBytes(Paths.get(System.getProperty("user.dir")+"\\src\\test\\resources\\UserDetails2833.json")))));
    }

}
