How to post x-www-urlencode request by rest assured

Question

I have a post request where i need to send x-www-form-urlencoded keyValue pair parameters and content-type should be x-www-form-urlencoded.

Before coding ,i've tried in postman successfully,just adding Header"Content-Type=application/x-www-form-urlencoded" with x-www-form-urlencoded body .

Here is my code:`

 RestAssured.baseURI="****"
        RequestSpecification request = RestAssured.given().config(RestAssured.config()
                .encoderConfig(EncoderConfig.encoderConfig()
                .encodeContentTypeAs("x-www-form-urlencoded",
                 ContentType.URLENC)))
                .contentType(ContentType.URLENC.withCharset("UTF-8"))
                .formParam("grant_type", *)
                .formParam("code", *)
                .formParam("client_id",*)
                .when().log().all()
                .then().log().all().request()
        request.post("/oauth2/token")`

I guess rest assured posted as formParam not "x-www-form-urlencoded"? This is rest assured log: `

Proxy:          <none>
Request params: <none>

Only support Content-Type：application/x-www-form-urlencoded

` This problem drives me crazy for a couple f days . Please do let me know is there any other way to send x-www-form-urlencoded parameters or some updation required in code.

Thanks a lot!

Answer 1

I had the same issue and I finally found the solution:

Understanding the issue: Rest Assured automatically concatenates a charset after the content type, even if you do not specify one.

i.e if you set the Content-Type to be application/x-www-form-urlencoded it will automatically set a default charset to it and your log will display:

Content-Type=application/x-www-form-urlencoded; charset=ISO-8859-1 or some other charset.

My problem was that I needed the content type to be without any charset, otherwise it was not accepted and returned status code 400.

The solution is to make sure you send the content type WITHOUT ANY charset.

How to use: Before you set the content type, add this line:

RequestSpecification rs= RestAssured.given();

rs.config(RestAssured.config().encoderConfig(encoderConfig().appendDefaultContentCharsetToContentTypeIfUndefined(false)));

this part : 
appendDefaultContentCharsetToContentTypeIfUndefined(false)))

will make sure that no charset will be appended to your content type.

Then set the header:

rs.header("Content-Type", "application/x-www-form-urlencoded");

This Method is working for me

public String getAuthForKeyCloak() {

    Response response = RestAssured.given().with().auth().preemptive()
            .basic(props.get("keycloak_username"), props.get("keycloak_password"))
            .header("Content-Type", "application/x-www-form-urlencoded")
            .formParam("grant_type", props.get("keycloak_granttype"))
            .formParam("client_id", props.get("keycloak_clientid"))
            .formParam("username", props.get("keycloak_username"))
            .formParam("password", props.get("keycloak_password")).when()
            .post(ApplnURIForKeyCloak + props.get("keycloakAuthURL"));

    System.out.println(response.getBody().asString());

    String responseBody = response.getBody().asString();
    String token = new org.json.JSONObject(responseBody).getString("access_token");
    System.out.println(token);
    return token;
    }

Response response = RestAssured
    .given()
    .contentType("application/x-www-form-urlencoded; charset=utf-8")
        .formParam("grant_type", "password")
        .formParam("username", user_email)
        .formParam("password", user_password)
        .formParam("audience", audience)
        .formParam("scope", "openid email")
        .formParam("client_id", REGULAR_APP_CLIENT_ID)
        .formParam("client_secret", REGULAR_APP_SECRET_ID)
    .when()
        .post(AUTH0_URL);

Use RA EncoderConfig to encode the content type for content-type x-www-form-urlencoded. Also, post the payload as form parameters

RequestSpecBuilder.setConfig(RestAssured.config().sslConfig(SSLConfig.sslConfig().relaxedHTTPSValidation())
                .encoderConfig(EncoderConfig.encoderConfig()
                        .encodeContentTypeAs("x-www-form-urlencoded",
                                ContentType.URLENC)))
                .setContentType("application/x-www-form-urlencoded; charset=UTF-8");

Answer 5

If you need send request with params in body:

String body = String.format("grant_type=%s&code=%s&clientid=%s", grantType, code, clientId);
Response response = given().with().
header("Content-Type", "application/x-www-form-urlencoded").
body(body).
post("/oauth2/token");

Case for params in URL:

Response response = given().with().
header("Content-Type", "application/x-www-form-urlencoded").
post("/oauth2/token?grant_type={type}&code={code}&clientid={id}");

Case for params in header (also might use Header object io.restassured.http.Header):

Response response = given().with().
header("Content-Type", "application/x-www-form-urlencoded").
header("grant_type", type).
header("code", code).
header("clientid", id).
post("/oauth2/token");

BTW use static give() for don't duplicate Config

public static RequestSpecification given() {
RestAssured.config = RestAssured.config().
...;
return given().baseUrl(BASE_URL).contentType(ContentType.URLENC);
}
