Question

当我点击chrome中的按钮时，它会下载一个jpg文件。但是当我使用phantomjs时，它不会下载jpg，也不会出现任何错误。

示例：https://deepak5j.github.io/HelloProjectPage/download.html

如何使用phantomjs下载文件？

Answer 1

var casper = require("casper").create();

casper.start('https://deepak5j.github.io/HelloProjectPage/download.html', function() {
    var url = 'https://raw.githubusercontent.com/Deepak5j/WebImages/master/Tiles/';
    this.download(url, 'sun_tile.jpg');
});

casper.run(function() {
    this.exit();
});

使用幻像按钮单击不会下载文件但单击后您可以将文件作为输入流。因此，您可以将输入流保存到文件。下面的代码将给出一个想法：

driver.findElement(By.className("Download")).click();
List<LogEntry> harLogEntries = driver.manage().logs().get("har").getAll();
LogEntry lastLogEntry = harLogEntries.get(harLogEntries.size() - 1);
String lastRequestUrl = getRequestUrlFromHarLogEntry(lastLogEntry);
DefaultHttpClient client;
HttpResponse response;
HttpGet get = new HttpGet(lastRequestUrl);
response = client.execute(get);
InputStream dataStream = response.getEntity().getContent();

我将在下面分享getRequestUrlFromHarLogEntry：

private String getRequestUrlFromHarLogEntry(LogEntry logEntry)
        throws  Exception {
    ObjectMapper objectMapper = new ObjectMapper();
    Map<String, Object> message = objectMapper.readValue(logEntry.getMessage(), Map.class);
    Map<String, Object> log = (Map<String, Object>) message.get("log");
    List<Object> entries = (List<Object>) log.get("entries");
    Map<String, Object> lastEntry = (Map<String, Object>) entries.get(entries.size() - 1);
    Map<String, Object> request = (Map<String, Object>) lastEntry.get("request");
    String url = (String) request.get("url");
    return url;
}

希望这会有所帮助..
