原理
CocoaHTTPServer框架能夠在iOS上建立起一個(gè)本地服務(wù)器恬涧，只要電腦和移動(dòng)設(shè)備連入同一熱點(diǎn)，即可使用電腦訪問iOS服務(wù)器的頁面搜立，利用POST實(shí)現(xiàn)文件的上傳昆淡。
實(shí)現(xiàn)
CocoaHTTPServer沒有現(xiàn)成的向iOS設(shè)備傳輸?shù)腟ample，我通過學(xué)習(xí)OS X端的Sample實(shí)現(xiàn)了iOS端的文件傳輸盒件，按照下面的步驟配置即可。
1.下載CocoaHTTPServer
2.解壓后舱禽，將CocoaHTTPServer-master目錄下的Core導(dǎo)入工程炒刁。
3.打開Samples/SimpleFileUploadServer，將其中的MyHTTPConnection類文件誊稚、web文件夾導(dǎo)入工程翔始。
4.打開Vendor罗心，將其中的CocoaAsyncSocket、CocoaLumberjack文件夾導(dǎo)入城瞎。
5.打開工程渤闷，打開MyHTTPConnection.m，根據(jù)標(biāo)記#pragma mark multipart form data parser delegate跳轉(zhuǎn)或者直接找到139行脖镀，- (void) processStartOfPartWithHeader:(MultipartMessageHeader*) header方法飒箭，將其中filePath的值修改為iOS的某個(gè)目錄，這個(gè)路徑是上傳的文件存儲(chǔ)的路徑蜒灰，這里以Caches為例：
// NSString* uploadDirPath = [[config documentRoot] stringByAppendingPathComponent:@"upload"];
NSString *uploadDirPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];
6 例子如下
var localHttpServer:HTTPServer!
func setupLocalHttpServer() {
// setupLocalHttpServer()\
localHttpServer = HTTPServer.init()
localHttpServer.setType("_http.tcp")
let fileM = FileManager.init()
// YalaaUpload
if let webPath = Bundle.main.path(forResource: "web", ofType: nil) {
if fileM.fileExists(atPath: webPath) {
print("web \(webPath)")
localHttpServer.setDocumentRoot(webPath)
localHttpServer.setConnectionClass(MyHTTPConnection.classForCoder())
// [httpServer setConnectionClass:[MyHTTPConnection class]];
self.startServer()
}
}
}
func startServer() {
do {
try localHttpServer.start()
let port = localHttpServer.listeningPort()
print("port \(port)")
if let ip = self.getWifiIP() {
print("address http://\(ip):\(port)")
}
} catch let err {
print("error \(err)")
}
}
//獲取本機(jī)無線局域網(wǎng)ip
func getWifiIP() -> String? {
var address: String?
var ifaddr: UnsafeMutablePointer<ifaddrs>? = nil
guard getifaddrs(&ifaddr) == 0 else {
return nil
}
guard let firstAddr = ifaddr else {
return nil
}
for ifptr in sequence(first: firstAddr, next: { $0.pointee.ifa_next }) {
let interface = ifptr.pointee
// Check for IPV4 or IPV6 interface
let addrFamily = interface.ifa_addr.pointee.sa_family
if addrFamily == UInt8(AF_INET) || addrFamily == UInt8(AF_INET6) {
// Check interface name
let name = String(cString: interface.ifa_name)
if name == "en0" {
// Convert interface address to a human readable string
var addr = interface.ifa_addr.pointee
var hostName = [CChar](repeating: 0, count: Int(NI_MAXHOST))
getnameinfo(&addr,socklen_t(interface.ifa_addr.pointee.sa_len), &hostName, socklen_t(hostName.count), nil, socklen_t(0), NI_NUMERICHOST)
address = String(cString: hostName)
}
}
}
freeifaddrs(ifaddr)
return address
}
注意事項(xiàng)如果沒有網(wǎng)絡(luò)請(qǐng)求的情況下弦蹂，您的app 是無法獲取到網(wǎng)絡(luò)權(quán)限的，獲取不到網(wǎng)絡(luò)權(quán)限强窖，您的app 就無法使用局域網(wǎng)傳輸文件建議您在設(shè)置之前凸椿，這樣加句代碼
