Swift：cUrl 等效 Alamofire 请求

Posted 2023-02-24

【中文标题】Swift：cUrl 等效 Alamofire 请求

【英文标题】：Swift: cUrl equivalent Alamofire request

【问题描述】：

我明白这不是传统方式，但我受客户约束。

cUrl 相当于什么

Expected

curl -v -X POST -H "Authorization: Basic XXXX==" -d Rules='[\"some\":\"thing\"]' "xyz.com/rules"

专注于 -d 内部的 Rules 字段

使用

struct Parameters: Encodable 
    let Rules: [ [String : String] ]


Session().request(
    "xyz.com",
    method: .post,
    parameters: Parameters(),
    encoder: JSONEncoder()
).cURLDescription  description in
    print("cURLDescription: ", description)

这将导致

Present

curl -v -X POST -H "Authorization: Basic XXXX==" -d '"Rules":"[\"some\": \"thing\"]' "xyz.com/rules"

但这不是预期的，需要产生上述Expected cUrl 命令的东西

【问题讨论】：

Rules='[\"some\":\"thing\"]'：这不是 JSON。相反，为自己创建一个解析器，它将从Parameters 生成它。然后就可以看到***.com/questions/27855319/…

【参考方案1】：

import Foundation
#if canImport(FoundationNetworking)
import FoundationNetworking
#endif

var semaphore = DispatchSemaphore (value: 0)

var postData: Data? = nil
if let data = "Rules=\"some\":\"thing\"".data(using: .utf8) 
    postData = Data(base64Encoded: data)

var request = URLRequest(url: URL(string: "xyz.com/rules")!,timeoutInterval: Double.infinity)
request.addValue("Basic XXXX==", forHTTPHeaderField: "Authorization")
request.addValue("application/x-www-form-urlencoded", forHTTPHeaderField: "Content-Type")

request.httpMethod = "POST"
request.httpBody = postData

let task = URLSession.shared.dataTask(with: request)  data, response, error in
  guard let data = data else 
    print(String(describing: error))
    semaphore.signal()
    return
  
  print(String(data: data, encoding: .utf8)!)
  semaphore.signal()


task.resume()
semaphore.wait()

使用这个扩展来打印 curlString。 https://gist.github.com/shaps80/ba6a1e2d477af0383e8f19b87f53661d

【讨论】：

这仍然会生成 Present 请求，而不是 Expected 请求
