amazon-s3

问题 I have a serverless website on AWS S3. But S3 have a limitation that I want to overcome: it don't allow me to have friendly URLs. For example, I would like to replace URL: www.mywebsite.com/user.html?login=daniel With this URL friendly: www.mywebsite.com/user/daniel So, I would like to know if I can use Lambda together with API Gateway to achieve this. My idea is: API Gateway ---> Lambda function ---> fetch S3 resource The API Gateway will get ANY request, and pass information to a Lambda

问题 I'm using django-oscar ,and wanted to serve my static files with AWS S3. To config my s3 bucket I've created a module called aws with conf.py and utils.py files. On my website when I upload an image to the product it gets uploaded well with the correct path to my aws s3 bucket, but then after very short time the path changes from https://mybucketname.s3.amazonaws.com/media/cache/..../image.jpg to https://mybucketname.s3.amazonaws.com/cache/..../image.jpg The images are in the media folder in

问题 I am trying to append a string to the end of a text file stored in S3. Currently I just read the contents of the file into a String, append my new text and resave the file back to S3. Is there a better way to do this. I am thinkinig when the file is >>> 10MB then reading the entire file would not be a good idea so how should I do this correctly? Current code [code] private void saveNoteToFile( String p_note ) throws IOException, ServletException { String str_infoFileName = "myfile.json";

问题 You can use S3 Select with Spark on Amazon EMR and with Databricks, but only for CSV and JSON files. I am guessing that S3 Select isn't offered for columnar file formats because it wouldn't help that much. Let's say we have a data lake of people with first_name , last_name and country columns. If the data is stored as CSV files and you run a query like peopleDF.select("first_name").distinct().count() , then S3 will transfer all the data for all the columns to the ec2 cluster to run the

问题 I've been using browser based direct POST uploads with Amazon S3 for a while, and just recently wanted to start posting through HTTPS. Normal HTTP posts work just fine. However, when I post the same form to https://s3.amazonaws.com/, I get a "405 Method Not Allowed". Do browser based direct AWS POST uploads not support HTTPS? If they do, how can I do it without getting a 405 error? Thanks! 回答1: It could be some problem with your HTML FORM action. The action specifies the URL that processes

问题 I'm trying to host a static site in S3 with ability to handle some dynamic content using Lambda/Api Gateway. Can't seem to be able to do that. I want URLs to look like this: example.com/index.html example.com/images/* example.com/css/* example.com/api/* -> API Gateway Also, when redirecting I'd like to keep the example.com as a root domain. I tried RoutingRules in S3, but redirects from the client. I need this to be transparent from the user, like proxying requests. 回答1: You can configure

问题 The title basically explains itself. I have a REST endpoint with VertX . Upon hitting it, I have some logic which results in an AWS-S3 object. My previous logic was not to upload to S3 , but to save it locally. So, I can do this at the response routerCxt.response().sendFile(file_path...) . Now that the file is in S3, I have to download it locally before I could call the above code. That is slow and inefficient. I would like to stream S3 object directly to the response object. In Express , it
