如何将http请求打印到控制台

是否可以在执行实际请求之前打印整个http(s)请求?

这是我的代码:

let postsEndpoint: String = "https://www.example.com/api/"
guard let postsURL = NSURL(string: postsEndpoint) else {
    throw APICallError.other("cannot create URL")
}
let postsURLRequest = NSMutableURLRequest(URL: postsURL)
postsURLRequest.HTTPMethod = "POST"
print(UTF8EncodedJSON)
postsURLRequest.HTTPBody = UTF8EncodedJSON
print(postsURLRequest) 

let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let session = NSURLSession(configuration: config)

let task = session.dataTaskWithRequest(postsURLRequest, completionHandler: {
    (data, response, error) in
    //handle response
})

首先以十六进制打印json然后:

<NSMutableURLRequest: 0x7fdae8d1dd30> { URL: https://www.ritzie.nl/api/v2 }

这对我没有多大帮助。我只想打印我的整个请求,就像你在Firefox上的firebug中看到它一样。

澄清一点,我不打算打印我的json。关于SO已经有足够的问题了。我希望我的完整请求打印出类似这样的内容:

POST /api/v2/ HTTP/1.1

HTTP headers:
Host: www.example.ocm
Origin: http://www.example.com
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/\*;q=0.8
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_2) AppleWebKit/601.3.9 (KHTML, like Gecko) Version/9.0.2 Safari/601.3.9
Referer: http://www.ritzie.nl/api/test.php
Accept-Language: en-us
Accept-Encoding: gzip, deflate

request body:
data=%7B%22action%22%3A+%22vehicleRecords%22%2C%0D%0A%22token%22%3A+%22token_04e01fdc78205f0f6542bd523519e12fd3329ba9%22%2C%0D%0A%22vehicle%22%3A+%22vehicle_e5b79b2e%22%7D

在completionHandler中打印:

let task = session.dataTaskWithRequest(postsURLRequest, completionHandler: {
    (data, response, error) in
    //handle response
     print(NSString(data: data.HTTPBody!, encoding:NSUTF8StringEncoding)!)
})

如果它不起作用,请使用以下内容:

print(NSString(data: data, encoding: NSUTF8StringEncoding))

这个适用于我:

    let task = session.dataTaskWithRequest(postsURLRequest, completionHandler: {
        (data, response, error) in
        if let _data = data
        {
            do {
                var jsonResult: NSDictionary
                try jsonResult = NSJSONSerialization.JSONObjectWithData(_data, options: NSJSONReadingOptions.MutableContainers) as! NSDictionary
                print("AsSynchronous\(jsonResult)")
            }
            catch {
                // handle error
            }
        }
        else
        {
            print("Error: no data for request \(urlPath)")
        }
    })

我认为您正在寻找类似的东西

        print("\(URLRequest.httpMethod ?? "") \(URLRequest.url)")
        let str = String(decoding: URLRequest.httpBody!, as: UTF8.self)
        print("BODY \n \(str)")
        print("HEADERS \n \(URLRequest.allHTTPHeaderFields)")

您可以使用CustomStringConvertible或CustomDebugStringConvertible生成有关URLRequest扩展的描述。您可以在返回字符串中包含所需的属性。

extension URLRequest /*: CustomStringConvertible*/{
    public var description: String{
        get{
            return "HEADERS \n \(String(describing: allHTTPHeaderFields))"
        }
    }
}

Use : print(<session task>.currentRequest?.description)

let task = session.dataTaskWithRequest(postsURLRequest, completionHandler: {
    (data, response, error) in
    //handle response
     print(NSString(data: response.request, encoding:NSUTF8StringEncoding)!)
})
