问题 I have developed an iOS application which can upload larger videos to an Amazon S3 server In order to do that, I have used : 1 Amazon V1 API 2 NSURLSession to upload videos to support background uploads . I have integrated a MD5 checksum to my put request to in-order to validate after file uploaded to Amazon server. NSString *md5 = [FileHash md5HashOfFileAtPath:[url path]]; NSMutableData *commandToSend= [[NSMutableData alloc] init]; unsigned char whole_byte; char byte_chars[3] = {'\0','\0','

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: Amazon API library for Python? I'm wanting to use the python-amazon-product-api wrapper to access the Amazon API: http://pypi.python.org/pypi/python-amazon-product-api/ Unfortunately it relies on lxml which is not supported on Google Appengine. Does anyone know a workaround? I'm only looking to do basic stuff with the API so could I use Elementtree instead? I'm a newbie so using anything other than how it comes

问题 i can't successfully connect to RDS from Amazon Lambda in production. For Amazon Lambda i'm using Serverless framework, executing sls offline i can connect with RDS from localhost, but in production Amazon Lambda doesn't. Both are in same VPC, in same security group, that has all traffic inbound access, and a rule that is pointing to Vpc's CIDR. I have these permissions attached: AmazonRDSFullAccess, AWSLambdaFullAccess, AmazonVPCFullAccess, AWSLambdaExecute and

问题 Is it possible to point a top level domain like http://example.com to a amazon cloudfront distribution? I know it's possible with CNAME's but as far as i know i need to set a A-name record for the top level domain in the DNS settings. 回答1: Q. Can I point my zone apex (example.com versus www.example.com) at my Amazon CloudFront distribution? Yes. Amazon Route 53 offers a special type of record called an ‘Alias’ record that lets you map your zone apex (example.com) DNS name to your Amazon

问题 It seems that there is no way to create a database in Amazon DynamoDB with its own name, you can only create tables. But we would like to separate databases for Staging/Development/Production environments. How you resolved it? Created a new AWS account? thanks 回答1: I would recommend creating a separate DynamoDB account. It's good for a whole number of reasons: Assurance that test data isn't leaking into production (don't give prod credentials to test hosts) Ability to break out spending on

问题 So I feel like I must be missing something incredibly simple here, but I can't seem to figure out how to get a product's name alone from the Product Advertising API. For instance, if I go to look at this product, I see that the product is listed as "The First Years Ignite Stroller", and the "City Chic" color is selected. From the API, I can see Brand ("The First Years") and Color ("City Chic"), but Title returns "The First Years Ignite Stroller, City Chic", with no other apparent ways to get

问题 I have two tables, and some fields between that tables has many-to-many relationships. How can i implement this feature in Amazon DynamoDB? 回答1: Quick answer: Either in your code or denormalize your tables (store redundant data). Denormalize; in otherwords, store redundant data in the central "join" table so you can get all the information you want by querying that one table. This is probably your best option, but you need to remember to update all relevant records in the central table when

问题 I am using a PHP class for Amazon S3 and CloudFront - Link. But when I try to upload a file into a bucket, I get this error: [SignatureDoesNotMatch] The request signature we calculated does not match the signature you provided. Check your key and signing method. How to fix it? Thanks. 回答1: When you sign up for Amazon, you can create yourself a key pair (Amazon calls those access key ID and secret access key). Those two are used to sign requests to Amazon's webservices. Amazon re-calculates

问题 I've implemented the AWS core and S3 SDK to handle file upload. Unfortunately the upload is not working properly sometimes. (it seems to be only under wifi connection but i am no 100% sure about that fact) For some unknown reason the aws service is receiving a successful response even though the file hasnt finished uploading and then everything hangs. I can see that the Transfer Service is started, and for example the first file starts uploading properly and finishes but the second one never
