Julia wrapper for libCURL
This is a simple Julia wrapper around http://curl.haxx.se/libcurl/ generated using Clang.jl. Please see the libcurl API documentation for help on how to use this package.
using LibCURL # init a curl handle curl = curl_easy_init() # set the URL and request to follow redirects curl_easy_setopt(curl, CURLOPT_URL, "http://example.com") curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1) # setup the callback function to recv data function curl_write_cb(curlbuf::Ptr{Cvoid}, s::Csize_t, n::Csize_t, p_ctxt::Ptr{Cvoid}) sz = s * n data = Array{UInt8}(undef, sz) ccall(:memcpy, Ptr{Cvoid}, (Ptr{Cvoid}, Ptr{Cvoid}, UInt64), data, curlbuf, sz) println("recd: ", String(data)) sz::Csize_t end c_curl_write_cb = @cfunction(curl_write_cb, Csize_t, (Ptr{Cvoid}, Csize_t, Csize_t, Ptr{Cvoid})) curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, c_curl_write_cb) # execute the query res = curl_easy_perform(curl) println("curl url exec response : ", res) # retrieve HTTP code http_code = Array{Clong}(undef, 1) curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, http_code) println("httpcode : ", http_code) # release handle curl_easy_cleanup(curl)
This package uses the LibCURL_jll binary package to install compiled libCURL binaries on all supported platforms. The following products are defined in the jll
libcurl: ALibraryProductreferencing the shared librarycurl: AnExecutableProductreferencing the binary
This package also uses the MozillaCACerts_jll package to supply the Mozilla CA root certificate bundle. Note that the cacert symbol is re-exported from this package for ease of use.
cacert: AFileProductreferencing the Mozilla CA certificate bundle
Making SSL/TLS connections usually needs access to a CA certificate to validate peers. The Mozilla CA bundle can be used via this package. To use this certificate bundle, set the following option:
curl_easy_setopt(curl, CURLOPT_CAINFO, LibCURL.cacert)
