Question

现在我不知道为什么会发生这种情况，而fetch的功能正在我正在定位的网址上正确显示promises响应。但现在我在console日志中看到的只是一个登录页面的HTML代码，我没有改变任何东西，但为什么会发生这种情况？

const caseform = _doc.forms.namedItem('caseform');

    caseform.addEventListener("submit", e => {
        e.preventDefault();

        this._action = caseform["action"];
        this._method = caseform["method"];

        this._fd = new FormData(caseform);

        async function savecase() {
            this._params = {method: this._method, body: this._fd};
            this._response = await fetch(this._action, this._params);

            try {
                if(this._response.ok) {
                    return await this._response.text();
                }
            } catch(error) {
                return error;
            }
        }

        savecase()
            .then(result => {
                if(result === 'error_in_retention_requirements') {
                    _doc.querySelector('div[data-result-case-error]').style.display = 'block';
                    _doc.querySelector('div[data-result-case-error]').innerHTML = 'Please provide all rentention requirements.';
                    _doc.querySelector('div[data-result-case-error]').scrollIntoView();
                } else if(result === 'error_in_clearance_requirements') {
                    _doc.querySelector('div[data-result-case-error]').style.display = 'block';
                    _doc.querySelector('div[data-result-case-error]').innerHTML = 'Please provide all clearance requirements.';
                    _doc.querySelector('div[data-result-case-error]').scrollIntoView();
                }  else if(result === 'error_in_clearance_requirements') {
                    _doc.querySelector('div[data-result-case-error]').style.display = 'block';
                    _doc.querySelector('div[data-result-case-error]').innerHTML = 'Please provide all clearance requirements.';
                    _doc.querySelector('div[data-result-case-error]').scrollIntoView();
                } else {
                    console.log(result);
                }
            });
    });

这是在控制台日志中返回的返回文本
