PycURL is a Python interface to libcurlthe multiprotocol file transfer library. Beyond simple fetches however PycURL exposes most of the functionality of libcurl, including:. This will also install libcurl and other dependencies as needed. If not using pip, binary distributions in other formats are available on Bintray. For support questions, please use curl-and-python mailing list. Mailing list archives are available for your perusal as well. Bugs can be reported via GitHub.

If you do not have a patch to fix the bug, or at least a specific code fragment in PycURL that you believe is the cause, you should instead post your inquiry to the mailing list. Release Notes. Navigation index modules next PycURL 7. Beyond simple fetches however PycURL exposes most of the functionality of libcurl, including: Speed - libcurl is very fast and PycURL, being a thin wrapper above libcurl, is very fast as well.

PycURL was benchmarked to be several times faster than requests. Features including multiple protocol support, SSL, authentication and proxy options. Multi and share interfaces. Quick search. Oberhumer, Oleg Pudeyev. Created using Sphinx 1.Get a web page and store in a local file, make the local file get the name of the remote document if no file name part is specified in the URL, this will fail :.

This is similar to FTP, but you can use the --key option to specify a private key to use instead of a password. Note that the private key may itself be protected by a password that is unrelated to the login password of the remote system; this password is specified using the --pass option.

Typically, curl will automatically extract the public key from the private key file, but in cases where curl does not have the proper library support, a matching public key file must be specified using the --pubkey option. Without telling which method to use, curl defaults to Basic. You can also ask curl to pick the most secure ones out of the ones that the server accepts for the given URL, by using --anyauth.

When using a proxy, you must use the -u style for user and password. It does not have special support for FTP proxy servers since there are no standards for those, but it can still be made to work with many of them. If the proxy is specified with --proxy1. See the manual for your FTP proxy to determine the form it expects to set up transfers, and curl's -v option to see exactly what curl is sending.

HTTP 1. Using this, a client can request to get only one or more subparts of a specified document. Curl supports this with the -r flag.

python curl

Curl also supports simple ranges for FTP files as well. Then you can only specify start and stop position. Curl also supports ftp upload through a proxy, but only if the proxy is configured to allow that kind of tunneling. If it does, you can run curl in a fashion similar to:. If curl fails where it isn't supposed to, if the servers don't let you in, if you can't understand the responses: use the -v flag to get verbose fetching.

Curl will output lots of info and what it sends and receives in order to let the user see all client-server interaction but it won't show you the actual data.

To get even more details and information on what curl does, try using the --trace or --trace-ascii options with a given file name to log to, like this:.

The HTTP information is a lot more extensive. Note that headers stored in a separate file can be very useful at a later time if you want curl to use cookies sent by the server. More about that in the cookies section. It's easy to post data using curl. The post data must be urlencoded.

If there's a "normal" post, you use -d to post. The data must be properly URL encoded. This latter type supports things like file upload. If you want the contents to be read from a file, use filename as contents.Usually, I just need to enter the command in terminal and press return key.

However, I don't know how it works in python. I searched a lot and got confused. I tried to write a piece of code, although I could not fully understand. It didn't work. The error message is 'Parse Error'. Can anyone tell me how to fix it?

For Python 3, try doing this: import urllib.

PycURL is mature, very fast, and supports a lot of features. You will need libcurl headers and libraries installed to install PycURL from source. Sometimes it is more convenient to use an environment variable, if you are not directly invoking setup. The suite depends on packages nosebottle and cherrypy.

See man page for more details on available variables. Many APIs will accept both formats, so if you're using curl at the command line, it can be a bit easier to use the form urlencoded format instead of json because.

This gist provides examples for using both formats, including how to use sample data files in either format with your curl requests. While running the following command from cmd. It gives the error as '-d' is not recognized as an internal or external command, operable program or batch file.

I felt if curl provide any simple solution with out writing a script for making this happen. It was necessary to escape the quotes in the submitted JSON:. I don't konw how to post data also with payload image data. I use fastcgi do the server part. Vanshita you might have not set the pathset the environment path and try. Excuse me I am getting the following error, syntaxerror: unexpected token in json at position 0 at object.

If your API endpoint can only accept one at a single time, then you can write a bash script that traverses your json array and throws a curl command for each one of them.

Other languages besides bash are more "pretty" for doing this task, like Ruby or Python. Just discovered something that others might also find surprising.

python curl

If you want to push up some space-significant stuff like YAML, then -d is not your friend. Use --data-binary instead of --data-ascii - otherwise it strips out linefeeds.

Thanks,very informative. In fact you shouldn't use it at all. AaronBaldwin Thanks. How do I do it? Good luck! The advantage of using -T is that you can stream read which in the case of a file descriptor is immensely useful if you don't know the length, whereas --data and --data file will read the entire contents of the file into a buffer in memory before the POST is sent, but -T reads however many bytes the internal read callback expects and asynchronously begins writing, hence why this is a very dirty hack.

I don't know if this behavior was ever actually intended, I should probably e-mail the haxx list one of these days and find out for sure. Thanks for your response. Partially issue got resolved but still I stuck with the problem.What is HTTP?

HTTP is a set of protocols designed to enable communication between clients and servers. It works as a request-response protocol between a client and server.

python curl

A web browser may be the client, and an application on a computer that hosts a web site may be the server. The most elegant and simplest of above listed libraries is Requests. We will be using requests library in this article. To download and install Requests library, use following command:. OR, download it from here and install manually. An API Application Programming Interface enables you to access the internal features of a program in a limited fashion.

Important points to infer :. For requests library, parameters can be defined as a dictionary. These parameters are later parsed down and added to the base url or the api-endpoint. To understand the parameters role, try to print r. You will see something like this:. We use requests. The two arguments we pass are url and the parameters dictionary. This is achieved by using json method. Finally, we extract the required information by parsing down the JSON type object.

Making a POST request. Here again, we will need to pass some data to API server. We store this data as a dictionary. The two arguments we pass are url and the data dictionary.
