HTTP Post 请求 API - 解析 JSON 包裹在单引号中

Question

我的 API 只接受单引号 JSON。喜欢：

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

我在这里和互联网上都找不到明确的答案。

我在 JSON 上尝试了许多语法更改。

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

在字符串中插入单引号并将其转换为数据。

问题已解决：

    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")
    request.addValue("*/*", forHTTPHeaderField: "Accept")
    let jsonData = "'{\"api_secret\":\"asdfg\",\"uniqueid\":\"LDM23564GQQP\",\"pin\":\"94729\",\"password\":\"test1\",\"api_key\":\"key_api1234\"}'".data(using: .utf8)

    request.httpBody = jsonData
    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()

这是一个糟糕的设计 API。强制将 JSON 嵌入到单引号中，如果你不能告诉后端开发人员修复它，我建议你。

不过，如果您想让它起作用，您可以将单引号转换为 Data，然后将您称为 httpBody 的内容附加到该单引号前后。

强制展开的不良做法（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.whosebug.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"}'
