是否可以将 NSURLSession 发送的请求记录到控制台?我在身份验证方面遇到问题,如果无法查看请求,我将无法调试
最佳答案
这些方法将以干净的方式打印 HTTP 请求和响应:
class func log(request: URLRequest){
let urlString = request.url?.absoluteString ?? ""
let components = NSURLComponents(string: urlString)
let method = request.httpMethod != nil ? "\(request.httpMethod!)": ""
let path = "\(components?.path ?? "")"
let query = "\(components?.query ?? "")"
let host = "\(components?.host ?? "")"
var requestLog = "\n---------- OUT ---------->\n"
requestLog += "\(urlString)"
requestLog += "\n\n"
requestLog += "\(method) \(path)?\(query) HTTP/1.1\n"
requestLog += "Host: \(host)\n"
for (key,value) in request.allHTTPHeaderFields ?? [:] {
requestLog += "\(key): \(value)\n"
}
if let body = request.httpBody{
let bodyString = NSString(data: body, encoding: String.Encoding.utf8.rawValue) ?? "Can't render body; not utf8 encoded";
requestLog += "\n\(bodyString)\n"
}
requestLog += "\n------------------------->\n";
print(requestLog)
}
class func log(data: Data?, response: HTTPURLResponse?, error: Error?){
let urlString = response?.url?.absoluteString
let components = NSURLComponents(string: urlString ?? "")
let path = "\(components?.path ?? "")"
let query = "\(components?.query ?? "")"
var responseLog = "\n<---------- IN ----------\n"
if let urlString = urlString {
responseLog += "\(urlString)"
responseLog += "\n\n"
}
if let statusCode = response?.statusCode{
responseLog += "HTTP \(statusCode) \(path)?\(query)\n"
}
if let host = components?.host{
responseLog += "Host: \(host)\n"
}
for (key,value) in response?.allHeaderFields ?? [:] {
responseLog += "\(key): \(value)\n"
}
if let body = data{
let bodyString = NSString(data: body, encoding: String.Encoding.utf8.rawValue) ?? "Can't render body; not utf8 encoded";
responseLog += "\n\(bodyString)\n"
}
if let error = error{
responseLog += "\nError: \(error.localizedDescription)\n"
}
responseLog += "<------------------------\n";
print(responseLog)
}
示例:
---------- OUT ---------->
https://api.example.com/api/auth
POST /api/auth HTTP/1.1
Host: api.example.com
------------------------->
<---------- IN ----------
https://api.example.com/api/auth
HTTP/1.1 200 /api/auth
