The gzip module provides the GzipFile class, as well as theopen(), compress() and decompress() convenience functions.The GzipFile class reads and writes gzip-format files,automatically compressing or decompressing the data so that it looks like anordinary file object.
Note that additional file formats which can be decompressed by thegzip and gunzip programs, such as those produced bycompress and pack, are not supported by this module.
Constructor for the GzipFile class, which simulates most of themethods of a file object, with the exception of the truncate()method. At least one of fileobj and filename must be given a non-trivialvalue.
The new class instance is based on fileobj, which can be a regular file, anio.BytesIO object, or any other object which simulates a file. Itdefaults to None, in which case filename is opened to provide a fileobject.
When fileobj is not None, the filename argument is only used to beincluded in the gzip file header, which may include the originalfilename of the uncompressed file. It defaults to the filename of fileobj, ifdiscernible; otherwise, it defaults to the empty string, and in this case theoriginal filename is not included in the header.
The mode argument can be any of 'r', 'rb', 'a', 'ab', 'w','wb', 'x', or 'xb', depending on whether the file will be read orwritten. The default is the mode of fileobj if discernible; otherwise, thedefault is 'rb'. In future Python releases the mode of fileobj willnot be used. It is better to always specify mode for writing.
Read n uncompressed bytes without advancing the file position.At most one single read on the compressed stream is done to satisfythe call. The number of bytes returned may be more or less thanrequested.
This page discusses the conversion of files to and from a gzip-compressedstate. The page includes an overview of transcoding, best practices forworking with associated metadata, and compressed file behavior in Cloud Storage.
gzip is a form of data compression: it typically reduces the size of a file.This allows the file to be transferred faster and stored using less spacethan if it were not compressed. Compressing a file can reduce both costand transfer time. Transcoding, in Cloud Storage, is the automatic changingof a file's compression before it's served to a requester. When transcodingresults in a file becoming gzip-compressed, it can be considered compressive,whereas when the result is a file that is no longer gzip-compressed, it can beconsidered decompressive. Cloud Storage supports the decompressiveform of transcoding.
Decompressive transcoding allows you to store compressed versions of filesin Cloud Storage, which reduces at-rest storage costs, while stillserving the file itself to the requester, without any compression. This isuseful, for example, when serving files to customers.
indicates that the uploaded object is a plain-text file. While there is no checkto guarantee the specified Content-Type matches the true nature of anuploaded object, incorrectly specifying its type will at best cause requestersto receive something other than what they were expecting and could lead tounintended behaviors.
indicates that the uploaded object is gzip-compressed. As withContent-Type, there is no check to guarantee the specified Content-Encodingis actually applied to the uploaded object, and incorrectly specifying anobject's encoding could lead to unintended behavior on subsequent downloadrequests.
This gives the most information about the state of the object to anyoneaccessing it. Doing so also makes the object eligible for decompressivetranscoding when it is later downloaded, allowing client applications tohandle the semantics of the Content-Type correctly.
While it is possible to do so, a file that is gzip-compressed should not beuploaded with the compressed nature of the file omitted. For example, for agzip-compressed plain-text file, you should avoid only settingContent-Type: text/plain. Doing so misrepresents the state of the objectas it will be delivered to a requester.
This implies you are uploading a gzip-compressed object that has beengzip-compressed a second time, when that is not usually the case (if youactually plan to doubly compress a file, please see theusing gzip on compressed objects section below). Whendecompressive transcoding occurs on such an incorrectly reported object,the object is served identity encoded, but requesters think that theyhave received an object which still has a layer of compression associatedwith it. Attempts to decompress the object will fail.
Similarly, a file that is not gzip-compressed should not be uploaded withthe Content-Encoding: gzip. Doing so makes the object appearto be eligible for transcoding, but when requests for the object are made,attempts at transcoding fail.
Some objects, such as many video, audio, and image files, not to mention gzipfiles themselves, are already compressed. Using gzip on such objects offersvirtually no benefit: in almost all cases, doing so makes the object largerdue to gzip overhead. For this reason, using gzip on compressedcontent is generally discouraged and may cause undesired behaviors.
For example, while Cloud Storage allows "doubly compressed" objects (that is,objects that are gzip-compressed but also have an underlying Content-Type thatis itself compressed) to be uploaded and stored, it does not allow objects to beserved in a doubly compressed state unless their Cache-Control metadataincludes no-transform. Instead, it removes the outer, gzip, level ofcompression, drops the Content-Encoding response header, and serves theresulting object. This occurs even for requests with Accept-Encoding: gzip.The file that is received by the client thus does not have the same checksum aswhat was uploaded and stored in Cloud Storage, so any integrity checksfail.
This behavior arises because it is not possible to selecta range from a compressed file without first decompressing the file in itsentirety: each request for part of a file would be accompaniedby the decompression of the entire, potentially large, file, which wouldpoorly utilize resources. You should be aware of this behavior and avoidusing the Range header when using transcoding, as charges are incurredfor the transmission of the entire object and not just the range requested.For more information on allowed response behavior to requests with Rangeheaders, see the specification.
I have a 6mb txt file in Box.com site.Now i would like to download the file using api. as it takes time to download, i would like to download it as a gzipped file. As given here where we have to add accept-encoding header with the values "gzip, deflate". I have added this header but the file is not downloaded as zip file it has the same size as 6mb, if it is zipped then it should be less than one mb in size.
If the file is available to be downloaded, the response will be a 302 Found to a URL at dl.boxcloud.com. The dl.boxcloud.com URL is not persistent. Clients will need to follow the redirect in order to actually download the file. The raw data of the file is returned unless the file ID is invalid or the user does not have access to it.
The important point to note is that there is a client redirect to a non-persistent URL in order to download the file. When we check the sequence of headers that are passed as a part of the redirect request, you can see that the Accept-Encoding: gzip deflate is missing. I used Fiddler to try this out, you can use any other HTTP proxy or interceptor.
I have many XML-s and I downloaded using file or file_get_content, but the server administrator told me that through GZIP is more efficient the downloading. My question is how can I include GZIP, because I never did this before, so this solution is really new for me.
You shouldn't need to do any decoding yourself if you use cURL. Just use the basic cURL example code, with the CURLOPT_ENCODING option set to "", and it will automatically request the file using gzip encoding, if the server supports it, and decode it.
Unless you mean that compression is available on the server and you are fetching data over HTTP using PHP as the client - in which case the server will only compress the data if the client provides an "Accept-Encoding" request header including "gzip". In which case, instead of file_get_contents() you might use:
Well, based on your screenshot, you are NOT downloading the gzip compressed CSV file. You are trying to decompress the file on the fly from the server (most probably Knime does eventually download the file to a temp folder first).
That is not correct. Putting this path in your browser, does not download the file. I opens the online folder and shows you the file, and then you have to download the file by clicking on it for example.
The Transfer Files does not have the interaction of showing you the file for you to click download. You have to give the full path of the file. And again, this is clearly mentioned in the message from your screenshot (I wrote these comments without looking at the messages, and only noticed them after I wrote them).
If you need to share a large file or multiple files, a compressed file takes up less storage space and can be sent faster because of its smaller file size. Learn how to compress or uncompress files on your iPhone or iPod touch.
If you selected one file, a ZIP file with the same filename saves to that folder. If you selected multiple files, a ZIP archive named Archive.zip saves to that folder. To change its name, touch and hold on the ZIP archive, then select Rename. 041b061a72
