量角器browser.manage（）。logs（）。get（'performance'）未检索服务器响应主体

Question

Selenium服务器独立v 3.0.1 Chromedriver v2.42 Chrome：最新

我的afterEach函数中包含以下代码，该代码按预期失败。但是，当Jasmine期望失败并且我输出浏览器日志时，在日志对象中的任何地方都看不到响应正文吗？我在那里看到了所有标头数据，但没有响应正文。

这是我从另一个答案中提取的代码（我丢失了链接）。效果很好。

browser.manage().logs().get('performance').then(async function(browserLogs) {
            browserLogs.forEach(async function(browserLog) {
                var message = JSON.parse(browserLog.message).message;
                if (message.method == 'Network.responseReceived') {
                    await expect(errorCodes)
                        .not.toContain(message.params.response.status,
                            'A status code of ' + message.params.response.status + ' was returned for the following request:\n\n' + JSON.stringify(message, null, 2));
                };
            });
        });

因此，当我运行测试并发现500错误时，期望行会失败并转储浏览器日志对象，但没有响应正文或结果部分，因此我无法获得有关失败原因的详细信息。有任何想法吗？以下是测试失败时得到的示例输出。请注意，没有响应正文数据。
