ios - URLSession发送GET请求而不是POST

我就是这么做的

var request = URLRequest(url: url)
let methodString = mehtod.rawValue
request.httpMethod = "POST"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")
request.cachePolicy = .reloadIgnoringLocalAndRemoteCacheData

if let headers = headers {
    request.set(headers: headers)
}

if let parameters = parameters {
    do {
        let postParams =  try JSONEncoder().encode(parameters)
        let postData = postParams
        request.httpBody = postData
    }
    catch {
        print("error")
    }
}

let session = URLSession.shared

print(request)
print(request.allHTTPHeaderFields)
print(String(data: request.httpBody!, encoding: .utf8)!)
print(request.httpMethod)

session.dataTask(with: request) { (data, response, error) in

    let result: Result<Data>

    if let data = data {
        result = .success(data)
    }
    else if let error = error {
        result = .failure(error)
    }
    else {
        result = .failure(RESTError.unknownError)
    }

    completion(result)

    }.resume()

这就是我在查尔斯身上看到的

我试着发邮件，但不知怎的我发了GET请求。
另外，我从服务器得到错误：

{"message":"Method \"GET\" not allowed.","code":"method_not_allowed"}

原因可能是什么？

最佳答案

我想你可以使用session.uploadTask(with: request, from: uploadData)。
