Files, URIs, and URLs conflicting in Java

由 穿精又带淫゛_ 提交于 2019-12-22 08:27:57
问题 I am getting some strange behavior when trying to convert between Files and URLs, particularly when a file/path has spaces in its name. Is there any safe way to convert between the two? My program has a file saving functionality where the actual "Save" operation is delegated to an outside library that requires a URL as a parameter. However, I also want the user to be able to pick which file to save to. The issue is that when converting between File and URL (using URI), spaces show up as "%20"

Get parameter names collection from Java/Android url

由 半腔热情 提交于 2019-12-22 05:41:32
问题 It's absolutely strange, but I can't find any Java/Android URL parser that will be compatible to return full list of parameters. I've found java.net.URL and android.net.Uri but they are can't return parameters collection. I want to pass url string, e.g. String url = "http://s3.amazonaws.com/?AWSAccessKeyId=123&Policy=456&Signature=789&key=asdasd&Content-Type=text/plain&acl=public-read&success_action_status=201"; SomeBestUrlParser parser = new SomeBestUrlParser(url); String[] parameters =

Get current URI in Twig template

问题 Does anybody know how to get the current URI in a Twig template? I’ve read through the documentation and I’m unable to find the Twig function to do this. 回答1: {{ app.request.uri }} If you want to read it into a view variable: {% set uri = app.request.uri %} The app global view variable contains all sorts of useful shortcuts, such as app.session and app.security.token.user , that reference the services you might use in a controller. 来源： https://stackoverflow.com/questions/7881233/get-current

Android Wear deleting data on DataApi with deleteDataItems

由 空扰寡人 提交于 2019-12-22 05:15:15
问题 My question is simple: how to delete data from DataAPI? I have some data in the path "/model/model_id" and want to delete ALL the data in the "/model". I use the code: uri = new Uri.Builder().scheme(PutDataRequest.WEAR_URI_SCHEME).path("model"); PendingResult<DataApi.DeleteDataItemsResult> deleteDataItemsResultPendingResult = Wearable.DataApi.deleteDataItems(mGoogleApiClient, uri); deleteDataItemsResultPendingResult.await(); NOTHING HAPPENS on the wear side (the method onDataChanged is never

Best practices on using URIs as parameter value in REST calls

由 こ雲淡風輕ζ 提交于 2019-12-22 04:38:31
问题 I am designing a REST API where some resources can be filtered through query parameters. In some cases, these filter values would be resources from the same REST API. This makes for longish and pretty unreadable URIs. While this is not too much of a problem in itself because the URIs are meant to be created and manipulated programmatically, it makes for some painful debugging. I was thinking of allowing shortcuts to URIs used as filter values and I wonder if this is allowed according to the

Are IRIs valid as HTML attribute values?

由 寵の児 提交于 2019-12-22 04:33:15
问题 Is it valid HTML to use IRIs containing non-ASCII characters as attribute values (e.g. for href attributes) instead of URIs? Are there any differences among the HTML flavors (HTML and XHTML, 4 and 5)? At least RFC 3986 seems to imply that it isn't. I realize that it would probably be safer (regarding older and IRI-unaware software) to use percent encoding, but I'm looking for a definitive answer with regards to the standard. So far, I've done some tests with the W3C validator, and unescaped

Uri.parse() always returns null in unit test

由 不打扰是莪最后的温柔 提交于 2019-12-22 01:34:19
问题 This simple unit test always passes and I can't figure out why. @RunWith(JUnit4.class) class SampleTest { @Test testSomething() { Uri uri = Uri.parse("myapp://home/payments"); assertTrue(uri == null); } } What I have tried so far is using a "traditional" URI ( http://example.com ) but uri was also null . 回答1: Check if you have the following in your app's gradle file: android { ... testOptions { unitTests.returnDefaultValues = true } Uri is an Android class and as such cannot be used in local

一、Windows环境配置 1、准备好hadoop的完全分布式按照，具体按照步骤这里不再赘述 此处我的版本为hadoop2.7.6版本，环境配置为Hadoop的完全分布式按照，各个节点具体安排如下 1）机器地址映射关系 192.168.8.240 hadoop01 192.168.8.241 hadoop02 192.168.8.242 hadoop03 2）机器节点安排 hadoop01 namenode datanode nodemanager hadoop02 secondarynamenode datanode nodemanager hadoop03 resourcemanager datanode nodemanager HDFS：分布式文件 hadoop01为namenode，其他都为datanode（包括hadoop01自己） YARN：分布式计算 hadoop03为resourcemanager管理节点，其他为计算节点nodemanager 3）说明 namenode最好单独出来，减轻元数据负载压力 secondarynamenode最好不要与namenode放置在同一台机器进行冷备份 resourcemanager最好单独出来避免与nodemanager在同一台机器 4）注意 hadoop完全分布式环境启动注意 hdfs的启动和关闭可以在任意节点进行控制：
