Rest-Assured/JUnit返回HTTP錯誤代碼400

我在Spring引導中編寫了一個簡單的REST，並且以放心編寫的測試用例返回http代碼400，而它從curl正常工作。Rest-Assured/JUnit返回HTTP錯誤代碼400

服務：

@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; 
    } 
}

測試類：

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))); 
    } 
}

測試運行：

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()); 
    } 
}

測試輸出：

Executing test testStatus [customer.TestCustomer] with result: SUCCESS

行之後表示，其返回400：

DEBUG org.apache.http.impl.conn.DefaultClientConnection - 接收響應：HTTP/1.1 400

這裏的工作正常捲曲要求：

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 \

下面是與回報碼200捲曲反應和身體：

}

所以我我試圖弄清楚我做錯了什麼。有一件事讓我困惑，爲什麼放心的是在請求中添加'Content-length：0'頭部。我正在學習放心和JUnit測試框架，並且我試圖讓一個GET請求工作。任何幫助，將不勝感激。

確定在嘗試了幾件事情後找到了解決方案。顯然，Files.readAllBytes（）正在向令牌值添加換行符。所以我替換loadContentsFromFile方法來使用Scanner來讀取運行良好的文件。

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. 
}

所以這引起了頭"Authorization: <token>"去服務器，而無需換行和工作的其他人怎麼叫。

我不完全確定爲什麼Files.readAllBytes（）會添加換行符，因爲我在文件中沒有換行符。
