【问题描述】：

我正在尝试从网站获取 html 代码，如果网站代码像这样小：（https://abdelftahzowail.github.io/WriteUpsideDown/）我会得到完整的代码，但如果网站代码像这样大：（https://www.pixel4k.com/page/1?s=deadpool）我没有得到完整的代码

我尝试了Jsoup 和HttpURLConnection 并没有给我完整的代码

这是我的代码

        Thread thread = new Thread(() -> {
            try  {
                Document doc;
                doc = Jsoup.connect(editText.getText().toString())
                        .header("Accept-Encoding", "gzip, deflate")
                        .userAgent("Mozilla/5.0 (Windows NT 6.2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.69 Safari/537.36")
                        .maxBodySize(0)
                        .timeout(0)
                        .get();
                Log.i("IMPORTANT !!!!","doc ( "+editText.getText().toString()+" )\n"+doc);
            } catch (Exception e) {
                Log.i("IMPORTANT !!!!","error : "+e);
            }
        });
        thread.start();

这是我从这个网站获得的代码 (https://www.pixel4k.com/page/1?s=deadpool)

但这个应用程序 (https://play.google.com/store/apps/details?id=com.teejay.trebedit&hl=en&gl=US) 获取完整代码

我该怎么办？

【问题讨论】：

我怀疑线程在你得到整个文档之前就死了。你能把Thread.sleep(20 * 1_000 )放在thread.start之后看看它是否会改变行为吗？
@spi 没有做任何改变

【解决方案1】：

您正在获取所有数据（您的两个 url 和您的代码生成完整的 html），但是 android 记录器在您调用它时不会输出所有内容。

如果您尝试编写文件而不是日志语句，您很可能会注意到所有数据都可用。

参照。 What is the size limit for Logcat and how to change its capacity?

【解决方案2】：

我在 Java 中搜索了 String 的最大长度。据 this question 中的 Takahiko Kawasaki 所说，最大长度为 65536 个字符。

由于您使用的方法将网页的 HTML 代码写入 String，这意味着如果您尝试下载的网页小于 65.536 字节，您的代码将按预期工作。

我不知道你在获得网页的HTML代码后需要做什么，所以下面的建议可能不足以满足你的需要，但是：你是否尝试过将HTML代码存储在StringBuffer中String?
