通过 Rest Assured 获取 Rest API URI 的状态代码 415 但通过 Rest Client 工作正常

Question

Getting 415 error in rest assured. Same URI is working fine with Rest client in browser. From Rest client i am getting response code 200.

public static Response response;
public static String jsonAsString;


@BeforeClass
public static void setupURL()
{
    // here we setup the default URL and API base path to use throughout the tests
    RestAssured.baseURI = "######url##########";
    //RestAssured.basePath = "/api/v1";
    RestAssured.authentication = basic("password", "password");
    Header acceptJson = new Header("content-type", "application/json");
    //RestAssured.given().contentType(ContentType.JSON);
    RestAssured.given().header(acceptJson);
}

@Test
public void getImageThroughImageid(){
    RequestSpecification httpRequest = RestAssured.given();
    Response response = httpRequest.request(Method.GET, "/images/imageid");
    System.out.println(response.getStatusCode());

}

Answer 1

You're using the wrong header for your accept. content-type tells the server what request body you're sending; you want to use accept to tell the server what type of response you want.

Answer 2

Need to add Both

.header("Content-Type","application/json" )
 .header("Accept","application/json" )

Answer 3

Try this:

EncoderConfig encoderConfig = RestAssured.config().getEncoderConfig()
                      .appendDefaultContentCharsetToContentTypeIfUndefined(false);

RestAssured.config = RestAssured.config().encoderConfig(encoderConfig);

In my case problem was caused by rest assured, which appends "charset" to request header "content-type=application/json" . Such request header may be refused when the server is principled and strict comply RFC 7159

Answer 4

Simply update rest-assured dependency & try to post a payload.

Older rest-assured library appends charset after 'content-type' even if you explicitly set it "application/json".

Headers:        Accept=*/*
                Authorization=Bearer --token**
                Content-Type=application/json; charset=UTF-8

but new rest-assured library will furnish header this way..

Headers: Accept= / Authorization=Bearer --token** Content-Type=application/json

I updated below dependency which resolved my issue.

    <dependency>
        <groupId>io.rest-assured</groupId>
        <artifactId>rest-assured</artifactId>
        <version>5.3.0</version>
        <scope>test</scope>
    </dependency>
