赛普拉斯访问() 失败： 类型错误： 标头内容中的字符无效 [ "cookie" ]

Question

我知道错误原因是 cookie 中的无效字符，但就我而言，我更愿意在不修复 cookie 保存方式的情况下找到解决方法。错误堆栈跟踪为：

TypeError [ERR_INVALID_CHAR] [ERR_INVALID_CHAR]: Invalid character in header content ["cookie"]

修复错误的正确方法是在应用程序保存cookie时对其进行转义。但是，如果由于某种原因无法修复应用程序代码，解决方法可能是覆盖visit()命令并在每个请求结束时转义无效的 cookie：

Cypress.Commands.overwrite('visit', (originalFn, ...args) => {
const [ url, options ] = (() => {
if (typeof args[0] === 'object') {
const { url, ...options } = args[0];
return [ url, options ];
} else {
return args;
}
})();
if (options && options.__original) {
return originalFn(url, options);
} else {
escapeCookie("firstInvalidCookie");
escapeCookie("secondInvalidCookie");
return cy.visit(url, {
...options,
__original: true
});
}
});
function escapeCookie(name) {
return cy.getCookie(name, { log: false }).then(cookie => {
cy.clearCookie(name, { log: false });
if (cookie) {
cy.setCookie(name, encodeURIComponent(cookie.value), {
domain: 'my.domain.com',
log: false
});
}
});
}
