Scala download file scala.io.source.fromurl






















Scala's io library was just hack done to provide support for limited needs. There was an effort to provide a well-thought io library to Scala, which is currently hosted at assembla, with a github repository as well.. If you are going to use I/O for anything more than reading the occasional file on short-lived processes, you'd better either use Java libraries, or look at the I/O support.  · That's a simple, "new" way I do it with Scala. However, note that it handles timeouts very poorly, such as if the web service you're calling is down or running slowly. FWIW, here's an old approach I used to retrieve REST content (content from a REST URL).  · 结合Java IO流,读取任意文件. spark的源码是由scala和java共同编写而成的,Java的多线程. scala,本身的编程语言的功能,就不是特别的强大和完善,比如说,scala甚至不能很方便地写文件,必须依赖于java的io流才可以. 所以说,scala,其实主要就是针对某些特定领域的.


You want a Scala HTTP client you can use to make GET request calls. Solution. There are many potential solutions to this problem. This recipe demonstrates three approaches: A simple use of the topfind247.coL method; Adding a timeout wrapper around topfind247.coL to make it more robust; Using the Apache HttpClient library. That's a simple, "new" way I do it with Scala. However, note that it handles timeouts very poorly, such as if the web service you're calling is down or running slowly. FWIW, here's an old approach I used to retrieve REST content (content from a REST URL). 说明1:file=topfind247.cole("E:\topfind247.co"),其中Source中的fromFile()方法源自 import topfind247.co源码包,源码如下图: topfind247.coes(),返回的是一个迭代器-Iterator;源码如下:(topfind247.co).


Option 1: topfind247.cong will do the trick see the docs of apache commons io jar will be already present in any spark cluster whether its databricks or any other spark installation. Below is the scala way of doing this I have taken a raw git hub csv file for this example can change based on the requirements. How to download and save a file from the internet using Scala? I know this is an old question, but I just came across a really nice way of doing this: import topfind247.cos._ import topfind247.co import topfind247.co def fileDownloader(url: String, filename: String) = { new URL(url) # new File(filename)!!. def GetUrlContent(url: String): String ={ val result = topfind247.coL(url).mkString return topfind247.cong() } So I call this function, and get the response into a text. val response: String = GetUrlContent(url).toString() A little redundant I know but I tried everything. But here I run into problems.
