Error handling

If the problem occurs on the EasyCurl side then EasyCurlError exception will be thrown.

EasyCurl.EasyCurlError — Type
EasyCurlError{code} <: Exception

Type that is returned if curl_request fails on the libcurl side.

Fields

Examples

julia> curl_request("GET", "http://httpbin.org/status/400", interface = "9.9.9.9")
ERROR: EasyCurlError{45}(Failed binding local connection end)
[...]

julia> curl_request("GET", "http://httpbin.org/status/400", interface = "")
ERROR: EasyCurlError{7}(Couldn't connect to server)
[...]

Or, if the problem was caused by HHTP, a EasyCurlStatusError exception will be thrown.

EasyCurl.EasyCurlStatusError — Type
EasyCurlStatusError{code} <: Exception

Type that is returned if curl_request fails on the HTTP side.

Fields

  • code::Int64: The HTTP error code (see HTTP_STATUS_CODES).
  • message::String: The error message.
  • response::Response: The HTTP response object.

Examples

julia> curl_request("GET", "http://httpbin.org/status/400", interface = "0.0.0.0")
ERROR: EasyCurlStatusError{400}(BAD_REQUEST)
[...]

julia> curl_request("GET", "http://httpbin.org/status/404", interface = "0.0.0.0")
ERROR: EasyCurlStatusError{404}(NOT_FOUND)
[...]

Below is a small example of error handling.

Example

using EasyCurl

headers = Pair{String,String}[
    "User-Agent" => "EasyCurl.jl",
    "Content-Type" => "application/json",
]

try
    response = curl_request("GET", "http://httpbin.org/status/400", query = "echo=你好嗎",
        headers = headers, interface = "0.0.0.0", read_timeout = 30, retries = 1)
    # If the request is successful, you can process the response here
    # ...
catch e
    if isa(e, EasyCurlError{EasyCurl.CURLE_COULDNT_CONNECT})
        # Handle the case where the connection to the server could not be made
    elseif isa(e, EasyCurlError{EasyCurl.CURLE_OPERATION_TIMEDOUT})
        # Handle the case where the operation timed out
    elseif isa(e, EasyCurlStatusError{400})
        # Handle a 400 Bad Request error specifically
        rethrow(e)
    end
end
