Rest Assured/JUnit返回HTTP错误代码400

Question

我在Spring boot中编写了一个简单的REST，用rest assured编写的一个测试用例返回http代码400，而它在curl中运行良好。

服务：

@RestController
@RequestMapping("/customerService")
public class CustomerService
{
    private static final Logger logger = Logger.getLogger(CustomerService.class.getName());

    @RequestMapping(value = "/customers/{id}", 
        produces = { "application/hal+json", "application/json" }, 
        consumes = { "application/json" }, method = RequestMethod.GET)
    public ResponseEntity<Customer> getCustomer(@PathVariable (value="id") String id)
    {
        logger.debug("getCustomer ["+id+"]");

        Customer customer = new Customer();
        ResponseEntity<Customer> response = ResponseEntity.ok(customer);

        customer.id="10";
        customer.name="Foobar";
        customer.category="Elite";

        return response;
    }
}

测试类：

import org.junit.FixMethodOrder;
import org.junit.Test;
import org.junit.runners.MethodSorters;

import static com.jayway.restassured.RestAssured.given;
import static org.junit.Assert.assertNotNull;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

@FixMethodOrder (MethodSorters.NAME_ASCENDING)
public class TestCustomer 
{
    @Test
    public void testStatus() throws IOException
    {
        String token = this.loadContentsFromFile("./src/test/resources/user-token.txt");
        String response = 
                given()
                .header("Authorization",token).and().header("Accept","application/json")
                .contentType("application/json")
                .when()
                    .get("http://localhost:8080/customerService/customers/10")
                   .peek() // Use peek() to print the ouput
                    .asString();

        assertNotNull(response);
        System.out.println("body : " +response);
    }   
    public String loadContentsFromFile(String path) throws IOException 
    {
        return new String(Files.readAllBytes(Paths.get(path)));
    }
}

测试跑步者：

public class TestSuite {
    public static void main(String[] args) {
        Result result = JUnitCore.runClasses(TestCustomerService.class);

        for (Failure failure : result.getFailures()) {
            System.out.println(failure.toString());
        }

        System.out.println(result.wasSuccessful());
    }
}

测试输出:

以下行显示返回400：

下面是一个很好的curl请求:

curl -v --header 'Content-type: application/json' \
--header 'Authorization: eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJhZG1pbiIsImF1ZGllbmNlIjoid2ViIiwiY3JlYXRlZCI6MTQ3ODg4ODk0ODExNiwiZXhwIjoxNDc5NDkzNzQ4fQ.nA-5UY3L6HQP-TUjhYgMg1wcQa1Q1GQwPtGxbU3wgctO_c7vMmOd_hhG4Dj28x8dswivVBTCAXYJd1-37CQFfg' \
--request GET http://localhost:8080/customerService/customers/10 \

下面是返回代码为 200 和正文的 curl 响应：

所以我试图弄清楚我做错了什么。有一件事让我感到困惑，为什么放心是添加“内容长度：0”标头到请求。我正在学习放心和JUnit测试框架，我被困在试图让一个GET请求工作。任何帮助将不胜感激。

Answer 1

如果您正在使用URIBuilder或类似的东西，请确保移动它添加的所有字符，例如%3等

Answer 2

好的，在尝试了一些事情后找到了解决方案。显然，Files.readAllBytes（）正在向令牌值添加换行符。所以我替换了loadContentsFromFile方法，使用Scanner读取运行良好的文件。

public String loadContentsFromFile(String path) throws IOException 
{
    Scanner scanner=null;
    String text="";
    try
    {
        scanner= new Scanner(new File(path));
        text = scanner.next();
    }
    finally
    {
        scanner.close();
    }
    return text;
    //      return new String (Files.readAllBytes(Paths.get(path)),Charset.defaultCharset());
    //has a bug it adds a line break at the end.
}

因此，这导致标题“Authorization:

我不太清楚为什么是Files。readAllBytes（）添加了换行符，因为我在文件中没有换行符。
