Java 为什么要“得到”；类型错误：常数e的重新声明；用它刮的时候？

我想用刮刀刮。我正在运行下面的代码来获取网站的内容，但是得到了一个错误

private void htmlUnit() {

    String START_URL = "https://www.tradingview.com/symbols/BTCUSDT/?exchange=BINANCE";
    try {
        WebClient webClient = new WebClient(BrowserVersion.CHROME);
        webClient.getOptions().setJavaScriptEnabled(true);
        webClient.getOptions().setCssEnabled(false);
        webClient.waitForBackgroundJavaScript(10000);
        HtmlPage page = webClient.getPage(START_URL);
        System.out.println();
    } catch (IOException ex) {
        ex.printStackTrace();
    }

}

我得到的例外：

我编写了HTML抓取软件。我的工具用于生成外国新闻服务的翻译。提到这一点是为了解释本答案中的背景信息，这样您就可以了解HTML Scrape最有用的地方，以及最好避免的时间（可能效率低下且“有点”不必要）

在提供了的情况下，使用RESTAPI几乎总是“明智的”。这篇关于RESTAPI的Wikipedia文章包含以下复制（剪切和粘贴）的描述。我所看到或读到的几乎所有其他内容都提供了

JSON

作为对

web服务器查询的响应

遵守REST体系结构约束的Web服务API包括
称为RESTful API。[14]基于HTTP的RESTful API是用
以下方面：[15]


基本URI，例如标准HTTP方法（例如GET、POST、PUT、PATCH和DELETE）
定义状态转换数据元素的媒体类型（例如，Atom、微格式、application/vnd.collection+json、[15]：91–99等）
当前表示告诉客户机如何编写转换到所有下一个可用应用程序状态的请求。这
可以像URI一样简单，也可以像Java小程序一样复杂。[16]

一般来说，理解如何使用JSON API需要使用Java拥有的两个不同JSON解析器之一。其中一个位于
javax.json包层次结构树中，另一个位于
android.json开发平台包中。任何一个都将帮助您解析对RESTAPI的响应，而这些响应几乎总是比尝试在充满Java脚本的网站上运行Java脚本要好

以下是JSON解析的文档站点——同样，Java有两个常用的站点：


（旧Java包）
（更新版，适用于Android）

我提到我使用的HTML解析器，正是因为我试图解释，在某些情况下，获取所需数据的唯一方法是通过
HTML解析（甚至Java脚本执行），然而，当实际的API提供给“整个互联网”时用这些来代替是更好的

在谷歌上快速搜索可以发现数十种比特币交易员使用的RESTAPI，而使用我提到的JSON库解析这些响应会更聪明。这些链接是通过将“BitCount REST API”输入谷歌搜索栏直接复制的






您试图使用Selenium刮取的页面是
我见过更复杂的Java脚本/AJAX页面。可能吧
Selenium很难轻松执行该脚本。我有
在我的一生中多次出错，但我想我可以建议使用
比特币价格的不同
网站URL

您或多或少会遇到这个错误，因为HtmlUnit使用的js引擎与当前浏览器的js不完全兼容。
引擎从一个版本改进到另一个版本，但仍有很多工作要做

或者更技术性的-看看这个js文件。此代码中的某个地方是错误的原因

你可以设置

webClient.getOptions().setThrowExceptionOnScriptError(false);

让js引擎忽略错误并进一步处理js代码

还有最后一点

webClient.waitForBackgroundJavaScript(10000);

这不是一种选择。您必须在页面检索之后调用此函数

您的代码应该如下所示

String url = "https://www.tradingview.com/symbols/BTCUSDT/?exchange=BINANCE";
try (final WebClient webClient = new WebClient(BrowserVersion.FIREFOX)) {
    webClient.getOptions().setThrowExceptionOnScriptError(false);

    HtmlPage page = webClient.getPage(url);
    webClient.waitForBackgroundJavaScript(20_000);

    System.out.println(" ---- ");
    System.out.println(page.asText());
    System.out.println(" ---- ");
}

希望这有帮助。请记住，至少图表是基于画布呈现的，这意味着您可以使用asText（）实现这一点。
谢谢，我知道有很多付费API，比特币价格只是一个例子，还有其他类似这样的实时数据，我想从中获取，而且我没有使用我说过的
Selenium
，我正在使用
HtmlUnit
。
