如何使用 Selenium 2 发送 http RequestHeader？

Question

我需要发送一个带有一些修改过的标头的 Http 请求。在尝试Selenium.addCustomRequestHeader为 Selenium 2寻找与 Selenium RC 等效的方法几个小时后，我放弃并使用 JavaScript 来达到我的目的。我预计这会容易得多！

有人知道更好的方法吗？

这就是我所做的：

javascript.js

var test = {
    "sendHttpHeaders": function(dst, header1Name, header1Val, header2Name, header2Val) {
        var http = new XMLHttpRequest();

        http.open("GET", dst, "false");
        http.setRequestHeader(header1Name,header1Val);
        http.setRequestHeader(header2Name,header2Val);
        http.send(null);
    }
}

我的测试程序

// ...

@Test
public void testFirstLogin() throws Exception {
    WebDriver driver = new FirefoxDriver();

    String url = System.getProperty(Constants.URL_PROPERTY_NAME);
    driver.get(url);

    // Using javascript to send http headers
    String scriptResource = this.getClass().getPackage().getName()
        .replace(".", "/") + "/javascript.js";

    String script = getFromResource(scriptResource)
            + "test.sendHttpHeaders(\"" + url + "\", \"" + h1Name
            + "\", \"" + h1Val + "\", \"" + h2Name + "\", \"" + h2Val + "\");";
    LOG.debug("script: " + script);

    ((JavascriptExecutor)driver).executeScript(loginScript);

    // ...
}

// I don't like mixing js with my code. I've written this utility method to get
// the js from the classpath
/**
 * @param src name of a resource that must be available from the classpath
 * @return new string with the contents of the resource
 * @throws IOException if resource not found
 */
public static String getFromResource(String src) throws IOException {
    InputStream is = Thread.currentThread().getContextClassLoader().
            getResourceAsStream(src);
    if (null == is) {
        throw new IOException("Resource " + src + " not found.");
    }
    InputStreamReader isr = new InputStreamReader(is);
    BufferedReader br = new BufferedReader(isr);
    StringWriter sw = new StringWriter();
    PrintWriter pw = new PrintWriter(sw);

    String line = null;
    int nLines = 0;
    while (null != (line = br.readLine())) {
        pw.println(line);
        nLines ++;
    }
    LOG.info("Resource " + src + " successfully copied into String (" + nLines + " lines copied).");
    return sw.toString();
}

// ...

根据阿尔贝托的回答，如果您正在使用它，您可以将修改标头添加到 Firefox 配置文件中：

FirefoxDriver createFirefoxDriver() throws URISyntaxException, IOException {
    FirefoxProfile profile = new FirefoxProfile();
    URL url = this.getClass().getResource("/modify_headers-0.7.1.1-fx.xpi");
    File modifyHeaders = modifyHeaders = new File(url.toURI());

    profile.setEnableNativeEvents(false);
    profile.addExtension(modifyHeaders);

    profile.setPreference("modifyheaders.headers.count", 1);
    profile.setPreference("modifyheaders.headers.action0", "Add");
    profile.setPreference("modifyheaders.headers.name0", SOME_HEADER);
    profile.setPreference("modifyheaders.headers.value0", "true");
    profile.setPreference("modifyheaders.headers.enabled0", true);
    profile.setPreference("modifyheaders.config.active", true);
    profile.setPreference("modifyheaders.config.alwaysOn", true);

    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setBrowserName("firefox");
    capabilities.setPlatform(org.openqa.selenium.Platform.ANY);
    capabilities.setCapability(FirefoxDriver.PROFILE, profile);
    return new FirefoxDriver(capabilities);
}

不幸的是，您无法使用 Selenium 2 更改标头。这是团队的一个有意识的决定，因为我们正在尝试创建一个浏览器自动化框架来模拟用户可以执行的操作。
