Question

我有以下代码，它希望返回从http://developer.android.com加载的整个html文件内容。

（代码在Xtend中，但我认为无所谓）。

var html = try {
        var client = new OkHttpClient()
        var request = new Request.Builder()
                        .url("http://developer.android.com/")
                        .build()
        var response = client.newCall(request).execute()

        response.body.string
    } catch(IOException err) {
        e("HTML error", err.toString)
        return
    }

    Log.d("HTML", html)

几行html后，输出被切断了。

我也试过使用UrlConnection，但结果并没有什么不同。这是在实际设备（三星Galaxy Note 10.1运行非官方Cyanogen Mod）和AVD（Atom x64与Android 6.0）上测试的。

我也试过了一些网址，但结果却完全相同（响应在某处被切断）。

我真的不知道接下来该怎么做。你能建议吗？

Answer 1

在浏览器中实际加载页面后，一些数据加载了javaScript）下载javaScripts并对其进行分析）

Answer 2

试试这个：

public static String readResponseBody(Response response) throws IOException {
    BufferedReader reader = new BufferedReader(response.body().charStream());;
    StringBuilder stringBuilder = new StringBuilder();
    while (true) {
        String line = reader.readLine();
        if (line == null)
            break;
        stringBuilder.append(line);
    }
    return stringBuilder.toString();
}

Answer 3

向每位参与者道歉。似乎图书馆/平台按预期工作。问题可能在于DDMS。

我已经尝试阅读整个html，然后在DDMS上显示最后几个字符（使用Log类），结果显示它是html </html>的结束标记。我很确定结果会整体回归。

但是如果我将整个字符串放入日志函数中，那么它会被大约4000个字符切掉。可能是adb缓冲区限制或其他。

OkHttp / Android不会返回完整的结果
