javascript - Protractor 中失败 : unknown error: browser is not defined after browser.executeScript()

Question

我有从浏览器控制台使用 api 登录的方法。

    this.logInViaAPI = function (user) {
    browser.executeScript(function (user) {
        var xhr = new XMLHttpRequest();
        xhr.open("POST", '/api/v1/....', true);
        xhr.setRequestHeader('token', browser.params.tokens.token);
        xhr.setRequestHeader('Content-Type', 'application/json');
        xhr.send('{"email": "' + user.login + '", "password": "' + user.apipassword + '"}');
    });
};

并在测试中使用它

   beforeAll(function () {
    browser.get("");
});


it("test", function (){
    helpers.logInViaAPI(browser.params.regularUser);
    browser.refresh();
});

然后我收到下一个错误。也许我应该做一些其他的事情，但我没有想法。

Answer 1

您通过executeScript执行的脚本在其范围内不会有浏览器。您需要通过参数参数化您的脚本:

var token = browser.params.tokens.token;
browser.executeScript(function (arguments) {
    var token = arguments[0];
    ...
    xhr.setRequestHeader('token', token);
}, token);
