json - HTTP Post 请求 API - 解析用单引号括起来的 JSON

Question

我的 API 仅接受单引号包装的 JSON。喜欢:

'{"api_key":"key_api1234","api_secret":"asdfg","uniqueid":"LDM23564GQQP","password":"test1","pin":"94729"}'

我在这里或互联网上都找不到明确的答案。

我尝试了对 JSON 的许多语法更改。

let parameters = ["api_key": "key_api1234",
                      "api_secret": "asdfg",
                      "uniqueid": "LDM23564GQQP",
                      "password": "test1",
                      "pin": "94729"]

    guard let url = URL(string: "https://dev-api.authenticateuser") else { return }
    var request = URLRequest(url: url)
    request.httpMethod = "POST"
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    guard let httpBody = try? JSONSerialization.data(withJSONObject: parameters, options: []) else { return }
    request.httpBody = httpBody

    let session = URLSession.shared
    session.dataTask(with: request) { (data, response, error) in
        if let response = response {
            print(response)
        }

        if let data = data {
            do {
                let json = try JSONSerialization.jsonObject(with: data, options: [])
                print(json)
            } catch {
                print(error)
            }
        }

        }.resume()

我收到 500 错误

这是一个糟糕的 API 设计。 强制将 JSON 嵌入到单引号中，如果您无法告诉后端开发人员修复它，我建议您这样做。

不过，如果您希望它起作用，您只需将单引号转换为Data，然后将您所谓的httpBody，在前后附加该单引号即可。

强制解包的做法不好(使用 !)，但要强调逻辑:

let parameters = ["api_key": "key_api1234",
                  "api_secret": "asdfg",
                  "uniqueid": "LDM23564GQQP",
                  "password": "test1",
                  "pin": "94729"]

var request = URLRequest(url: URL(string: "www.stackoverflow.com")!)

let singleQuote = "'".data(using: .utf8)!
let parametersJSON = try! JSONSerialization.data(withJSONObject: parameters, options: [])

let finalBody = singleQuote + parametersJSON + singleQuote
print("request.httpBody string: \(String(data: finalBody, encoding: .utf8)!)")
request.httpBody = finalBody

输出:

$>request.httpBody string: '{"api_key":"key_api1234","uniqueid":"LDM23564GQQP","pin":"94729","password":"test1","api_secret":"asdfg"}'
