有没有办法使用 Alamofire(类似于 AFNetworkActivityLogger)记录每个请求/响应?
我知道 Printable、DebugPrintable 和 Output (cURL),但它们并不是我想要的。

有一个可爱的小豆荚:https ://github.com/konkab/AlamofireNetworkActivityLogger
将此添加到您的 podfile 中:
pod 'AlamofireNetworkActivityLogger', '~> 2.0'
在您的 AppDelegate 中:
import AlamofireNetworkActivityLogger
然后在你的didFinishLaunchingWithOptions
,添加这个:
NetworkActivityLogger.shared.level = .debug
NetworkActivityLogger.shared.startLogging()
编辑:我实际上在生产中遇到了崩溃。为了安全起见,使用“构建标志”仅在调试中使用它,如下所示:
#if DEBUG
NetworkActivityLogger.shared.level = .debug
NetworkActivityLogger.shared.startLogging()
#endif
像这样的东西可能是您正在寻找的东西:
extension Request {
public func debugLog() -> Self {
#if DEBUG
debugPrint(self)
#endif
return self
}
}
用法:
Alamofire.request(.GET, "http://httpbin.org/get", parameters: ["foo": "bar"])
.debugLog()
.response {…}
如果要打印所有响应,可以编写自己的响应方法,类似于本教程顶部的 responseObject() 方法:
http://www.raywenderlich.com/87595/intermediate-alamofire-tutorial
[更新:根据@trauzti 的要求在下面添加。]
以下是如何使用 responseObject() 方法来打印每个请求的输出。
警告讲师:我没有亲自测试过这段代码,并且可能会在生产中做出不同的选择。这只是显示了 Wenderlich 教程代码如何包含调试日志记录。另请注意:由于本教程是 Swift 2.0 之前的版本,因此我使用了旧的 println() 而不是 print()。
@objc public protocol ResponseObjectSerializable {
init(response: NSHTTPURLResponse, representation: AnyObject)
}
extension Alamofire.Request {
public func responseObject<T: ResponseObjectSerializable>(completionHandler: (NSURLRequest, NSHTTPURLResponse?, T?, NSError?) -> Void) -> Self {
let serializer: Serializer = { (request, response, data) in
#if DEBUG
println("Request: \(request.URL)")
#endif
let JSONSerializer = Request.JSONResponseSerializer(options: .AllowFragments)
let (JSON: AnyObject?, serializationError) = JSONSerializer(request, response, data)
if response != nil && JSON != nil {
#if DEBUG
println("Response:")
debugPrint(JSON)
#endif
return (T(response: response!, representation: JSON!), nil)
} else {
#if DEBUG
println("Failed Serialization:")
debugPrint(serializationError)
#endif
return (nil, serializationError)
}
}
return response(serializer: serializer, completionHandler: { (request, response, object, error) in
completionHandler(request, response, object as? T, error)
})
}
}
从 Alamofire 5 开始,最简单的方法是定义一个EventMonitor
子类:
final class AlamofireLogger: EventMonitor {
func requestDidResume(_ request: Request) {
let body = request.request.flatMap { $0.httpBody.map { String(decoding: $0, as: UTF8.self) } } ?? "None"
let message = """
⚡️ Request Started: \(request)
⚡️ Body Data: \(body)
"""
NSLog(message)
}
func request<Value>(_ request: DataRequest, didParseResponse response: DataResponse<Value>) {
NSLog("⚡️ Response Received: \(response.debugDescription)")
}
}
然后在您的会话中使用它:
let session = Session(eventMonitors: [ AlamofireLogger() ])
此示例代码改编自https://github.com/Alamofire/Alamofire/issues/2867#issuecomment-509662892
Timberjack 就是您正在寻找的东西。Timberjack 是一个简单的、非侵入式的网络活动记录器。记录您的应用程序发出的每个请求,或者如果您愿意,则仅限于使用特定 NSURLSession 的请求。如果这是你的事,它也适用于 Alamofire。
https://cocoapods.org/pods/Timberjack
用法:
import Alamofire
import Timberjack
class HTTPManager: Alamofire.Manager {
static let sharedManager: HTTPManager = {
let configuration = Timberjack.defaultSessionConfiguration()
let manager = HTTPManager(configuration: configuration)
return manager
}()
}
添加到 Alamofire 4.0+ Swift 3 的上述答案
extension DataRequest {
public func LogRequest() -> Self {
//Your logic for logging
return self
}
}
请求时
Alamofire.request(requestUrl, method: .post, parameters: parameter, encoding: JSONEncoding.default)
.LogRequest()
.responseJSON { response in
//Do your thing
}
如果您想在任何情况下取消请求(这是我想要的),您可以self.cancel()
在返回之前的任何地方
在 Alamofire 5 中,URLRequest 是异步创建的,这意味着
extension Request {
public func debugLog() -> Self {
#if DEBUG
debugPrint(self)
#endif
return self
}
}
不再是最好的解决方案。相反,cURLDescription
建议如下调用:
let request = AF.request(<Your request>))
request.cURLDescription { (curl) in
print("CURL \(curl)")
}
request.responseJSON { response in
//Do something with your response...
}
或者
extension Request {
public func debugLog() -> Self {
#if DEBUG
cURLDescription(calling: { (curl) in
debugPrint("=======================================")
print(curl)
debugPrint("=======================================")
})
#endif
return self
}
}
在 Alamofire 5.0.0 中,我使用了基于: https ://github.com/Alamofire/Alamofire/issues/2867#issuecomment-509662892 的答案, 但我不得不用 AFDataResponse 替换 DataResponse。例如:
import Alamofire
final class AlamofireLogger: EventMonitor {
func requestDidResume(_ request: Request) {
let allHeaders = request.request.flatMap { $0.allHTTPHeaderFields.map { $0.description } } ?? "None"
let headers = """
⚡️⚡️⚡️⚡️ Request Started: \(request)
⚡️⚡️⚡️⚡️ Headers: \(allHeaders)
"""
NSLog(headers)
let body = request.request.flatMap { $0.httpBody.map { String(decoding: $0, as: UTF8.self) } } ?? "None"
let message = """
⚡️⚡️⚡️⚡️ Request Started: \(request)
⚡️⚡️⚡️⚡️ Body Data: \(body)
"""
NSLog(message)
}
func request<Value>(_ request: DataRequest, didParseResponse response: AFDataResponse<Value>) {
NSLog("⚡️⚡️⚡️⚡️ Response Received: \(response.debugDescription)")
NSLog("⚡️⚡️⚡️⚡️ Response All Headers: \(String(describing: response.response?.allHeaderFields))")
}
}
然后您可以通过以下方式使用它:
let session = Session(eventMonitors: [ AlamofireLogger() ])
正如 0xced 在上述帖子中所解释的那样。
斯威夫特 3.0+ 的解决方案
对于打印请求参数和标头:
Alamofire.request(url, method: .get, parameters: parameters, headers: headers)
.validate()
.responseObject { (response: DataResponse<T>) in
self.pendingRequests.removeValue(forKey: endPoint)
completion!(response)
if(NetworkConfig.loggingEnable) {
debugPrint("************* printing REQUEST parameter and Headers *************")
debugPrint("RESPONSE : \(response.debugDescription)")
}
}.responseDebugPrint()
用于打印响应。使用下面的扩展名。
import Foundation
import Alamofire
extension Alamofire.DataRequest {
func responseDebugPrint() -> Self {
if NetworkConfig.loggingEnable {
return responseJSON() {
response in
if let JSON = response.result.value,
let JSONData = try? JSONSerialization.data(withJSONObject: JSON, options: .prettyPrinted),
let prettyString = NSString(data: JSONData, encoding: String.Encoding.utf8.rawValue) {
print(prettyString)
} else if let error = response.result.error {
print("Error Debug Print: \(error.localizedDescription)")
}
}
}
return self
}
}
给你的小要点: https ://gist.github.com/manishpathak99/348f2eb0167c0ff6e12ecd667612bc9b/edit
在 Alamofire 5 及更高版本中,您可以curl
通过以下代码获取请求详细信息:
request.cURLDescription(calling: { (curl) in
print(curl)
})
和响应/错误数据:
request.responseDecodable { (response:AFDataResponse<T>) in
switch response.result {
case .success(let value):
var responseMessage : String?
if let data = response.data {
let json = String(data: data, encoding: String.Encoding.utf8)
responseMessage = String(describing: json)
}
print(responseMessage)
break;
case .failure(let error):
var message : String?
if let data = response.data {
let json = String(data: data, encoding: String.Encoding.utf8)
message = String(describing: json)
}
print(message)
break
}
}
