在使用 Cypress 进行 API 测试时使用 GET 方法时避免 406 错误

Question

I would like to test the api of an application, I've got a token from the developer, but I'm getting an error 'cy.request() failed on:

https://******************************

The response we received from your web server was:

406: Not Acceptable

This was considered a failure because the status code was not 2xx or 3xx.' This is the code that I used:

describe('API Test', () => {
    const token = 'your_token_here';

    it('Should make a GET request with a Bearer token and avoid 406 error', () => {
        cy.request({
            method: 'GET',
            url: 'https://your-api.com/endpoint',
            headers: {
                'Authorization': `Bearer ${token}`,
                'Accept': 'application/json'
            }
        }).then((response) => {
            expect(response.status).to.eq(200);
            expect(response.body).to.be.an('object');
        });
    });
});

I tried with 'Accept': 'application/json' and 'Content-Type': 'application/json', but it didn't help.

Answer 1

the Content-type header is used to indicate the original media type of the resource. Here since you are sending a GET request content-type does not matter.

the Accept header is used by the sender of the request(browser) to specify response media types that are acceptable. So here in your case maybe the type of the response is not application/json that's why you are gettin an

406: Not Acceptable

I found also in this source that in some cases, the server could be responsible for the 406 Error since it's the.network object producing the error. Perhaps the server is misconfigured and can't handle the request correctly. Maybe it's a traffic routing issue.

so try your REQUEST without any header and if the 406 still occurs you are sure that it is from ther server and that your REQUEST is OK.
