在 moxios 中指定 response.request.responseURL

Specify response.request.responseURL in moxios

我目前正在尝试编写一些功能,需要在 axios 处理响应时设置 response.request.responseURL 值。但是,我似乎无法用 moxios 设置这个值。这是我的测试结果:

it('resets list selection if input contents were replaced', (done) => {
    component.currently_selected_list_value = 10;
    component.last_called_url = 'henkiehoutman';

    let input = domElt.querySelector('input');
    ReactTestUtils.Simulate.change(input);

    moxios.wait(() => {
        let request = moxios.requests.mostRecent();
        request.respondWith({
            status: 200,
            response: [{
                customer_info_customers: ['', '', '', '', ''],
                domain_info_customers: {},
            }],
            request: {responseURL: 'banaan'}
        }).then(() => {
            // The contents were replaced, so it's best to forget whatever our selection was.
            expect(component.currently_selected_list_value).toEqual(-1);
            done();
        });
    });
});

这是我的实际应用程序的样子:

onChange (event) {
    return axios.get(
        this.props.ApiUrl + encodeURIComponent(event.target.value)
    ).then(
        (response) => {
            let response_url = response.request.responseURL;  // This is the value I want to set manually.
            if(this.shouldHandleResponse(response_url)){
                this.last_called_url = response_url;
                let data = response.data;
                this.setState({results: data, dropdown: data.length > 0});

                if ( this.currently_selected_list_value > max_index) {
                    this.currently_selected_list_value = max_index;
                }
            }
        }
    );
},

但是,当我记录这个值是什么时,它只显示 undefined。这就是实际的 response.request 值(将其放在引号中以使其更具可读性):

LOG: Request{resolve: function (a) { ... }, reject: function (a) { ... }, config: Object{adapter: function mockAdapter(config) { ... }, transformRequest: Object{0: ...}, transformResponse: Object{0: ...}, timeout: 0, xsrfCookieName: 'XSRF-TOKEN', xsrfHeaderName: 'X-XSRF-TOKEN', maxContentLength: -1, validateStatus: function validateStatus(status) { ... }, headers: Object{Accept: ..., X-CSRFToken: ...}, method: 'get', url: 'my_api_url/', data: undefined}, headers: Object{Accept: 'application/json, text/plain, /', X-CSRFToken: 'my_csrf_token'}, url: 'my_api_url/', timeout: 0, withCredentials: false, responseType: undefined}

这会破坏我的应用程序,因为应该始终定义 responseURL。看起来它正在覆盖我在 moxios 中定义的请求。这不一定是坏事,因为我认为它需要这些东西才能正常运行。但是,如果我可以为此请求添加一些值,那就太好了。

所以;如何在 moxios 中向此请求添加 responseURL 值?

由于我将它链接到 respondWith() 的方式,所以无法设置 responseURL。在查看 moxios 源代码中的这个函数后,我发现你在这里传递的值实际上只与返回的实际数据有关,而不是实际的响应对象。

我还看到 respondWith() 函数 returns 一个 Promise 对象,这很合乎逻辑。我认为我不应该在 Promise 上设置任何内容,而是根据实际请求设置。因此,我将返回的 Promise 分配给了 promise 变量,并取消了测试的 .then() 部分。之后我设置了请求的responseURL。然后我再次调用 promise.then() 断言我的测试已经通过。

这是我最终的目标:

it('resets list selection if input contents were replaced', (done) => {
    component.currently_selected_list_value = 10;
    component.last_called_url = 'henkiehoutman';

    let input = domElt.querySelector('input');
    ReactTestUtils.Simulate.change(input);

    moxios.wait(() => {
        let request = moxios.requests.mostRecent();
        let promise = request.respondWith({
            status: 200,
            response: [{
                customer_info_customers: ['', '', '', '', ''],
                domain_info_customers: {},
            }],
        });
        request.responseURL = 'banaan';

        promise.then(() => {
            // The contents were replaced, so it's best to forget whatever our selection was.
            expect(component.currently_selected_list_value).toEqual(-1);
            done();
        });
    });
});
