I have built a command line tool, at some point, I need to execute a curl command. I'm creating the script that should be executed, but I don't know how.
I'm able to create the script and printing it out, but I'm not being able to execute it.
It looks something like: curl https://api.github.com/zen
Please ask me anything if it's not clear. I appreciate your help.
#!/usr/bin/env swift
import Foundation
func run(_ args: String...) -> Int32 {
let task = Process()
task.launchPath = "/usr/bin/env"
task.arguments = args
task.launch()
task.waitUntilExit()
return task.terminationStatus
}
run("curl", "https://api.github.com/zen")
curl https://api.github.com/zen. However, I'm trying to run another command like: curl -H 'Authorization: token USERTOKEN’ -H 'Accept: application/vnd.github.v3.raw' https://api.github.com/repos/USERNAME/REPO/contents/PATH by inserting double quotations and commas between each flag but I failed to done that. Please help me with that. I also would be so appreciative if you explained more on how the func above is working. Thanks
run("curl", "param1", "param2", "paramn"). See [variadic parameters](swift variadic parameters).You can run a Terminal command from Swift using NSTask (now called Process in Swift 3): If you need output, add let output = handle.readDataToEndOfFile() at the end. Here's the whole thing wrapped in a function (the launchPath would be /usr/bin/curl):
func runTask(launchPath: String, flags: [String]) -> String {
let task = Process()
let pipe = Pipe()
task.launchPath = launchPath
task.arguments = flags
task.standardOutput = pipe
let handle = pipe.fileHandleForReading
task.launch()
return String(data: handle.readDataToEndOfFile(), encoding: .utf8) ?? ""
}
In your case though, you might want to have a look at URLSession and URLRequest (superseding NSURLRequest). To create a request to your URL and credentials, you would simply do:
var request = URLRequest(url:URL(string: "https://api.github.com/zen")!)
request.setValue("application/vnd.github.v3.raw", forHTTPHeaderField: "Accept")
request.setValue("token USERTOKEN", forHTTPHeaderField: "Authorization")
let session = URLSession(configuration: .default)
session.dataTask(with: request, completionHandler: {(data, response, error) in
guard let data = data, error == nil else {
print("Error: \(error.debugDescription)")
return
}
guard let output = String(data: data, encoding: .utf8) as String? else {
print("Unable to format output data")
return
}
print(output)
}).resume()
curl -H 'Authorization: token USERTOKEN’ -H 'Accept: application/vnd.github.v3.raw' https://api.github.com/repos/USERNAME/REPO/contents/PATH @Oskarvar request = MutableURLRequest(URL:url), here what I did in main.swift: gist.github.com/MEnnabah/18ecf3fbd95ecee1466d08dab896fcc4 but it's not working.
curlhere. You'll probably have an easier time withNSURLRequest
