ios MKNetworkKit 的使用
常用框架比如：AFNetworking，ASIHttpRequest,SDWebImage,MKNetWorKit等。
iOS5已出来这么久了，而ASIHttpRequest的作者已经申明不更新了，在iOS5环境下，其实还是有些问题的。
现在MKNetWorkKi吸取了ASIHttpRequest与AFNetWorking的优点，并加入了自己特有的功能。
下载：
gitHub地址：https://github.com/MugunthKumar/MKNetworkKit.git
官方使用说明：http://blog.mugunthkumar.com/products/ios-framework-introducing-mknetworkkit/
github下载了该项目后，如果想运行其demo，一定要打开MKNetworkKit.xcworkspace该文件，若单独打开，则编译时会提示缺少libMKNetworkKit-iOS.a文件！！！
安装：
克隆下来之后把其中的 MKNetworkKit文件夹拖入项目，然后引入3个framework：
CFNetwork.Framework , SystemConfiguration.framework , Security.framework
注意：由于MKNetworkKit支持ARC，我们在项目中要开启ARC，不然会报错
开启ARC自动内存控制机制：(开启ARC之后项目中所有的dealloc 、release 、autorelease都得注释掉)
使用方法：
在需要使用的地方导入：#import"MKNetworkKit.h"
http方式：
GET请求：
[cpp] view plaincopy
MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:@"192.168.2.176:3000" customHeaderFields:nil];
MKNetworkOperation *op = [engine operationWithPath:@"/index" params:nil httpMethod:@"GET" ssl:NO];
[op addCompletionHandler:^(MKNetworkOperation *operation) {
NSLog(@"[operation responseData]-->>%@", [operation responseString]);
}errorHandler:^(MKNetworkOperation *errorOp, NSError* err) {
NSLog(@"MKNetwork request error : %@", [err localizedDescription]);
}];
[engine enqueueOperation:op];
POST请求：
[cpp] view plaincopy
MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:@"192.168.2.176:3000" customHeaderFields:nil];
NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
[dic setValue:@"admin" forKey:@"username"];
[dic setValue:@"123" forKey:@"password"];
MKNetworkOperation *op = [engine operationWithPath:@"/login" params:dic httpMethod:@"POST"];
[op addCompletionHandler:^(MKNetworkOperation *operation) {
NSLog(@"[operation responseData]-->>%@", [operation responseString]);
}errorHandler:^(MKNetworkOperation *errorOp, NSError* err) {
NSLog(@"MKNetwork request error : %@", [err localizedDescription]);
}];
[engine enqueueOperation:op];
https方式：
[cpp] view plaincopy
#define serverHost @"192.168.1.84:5558"
- (NSDictionary *)getDataFromURL:(NSString *)Path params:(NSDictionary *)data
{
NSLog(@"MKNetwork request URL: %@%@ \n Data: %@",serverHost,Path,data);
__block NSDictionary *responseJSON;
__block NSError *error = nil;
MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:serverHost customHeaderFields:nil];
MKNetworkOperation *op = [engine operationWithPath:Path params:data httpMethod:@"POST" ssl:YES];
// 在请求中添加证书
op.clientCertificate = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"client.p12"];
op.clientCertificatePassword = @"test";
// 当服务器端证书不合法时是否继续访问
op.shouldContinueWithInvalidCertificate=YES;
[op addCompletionHandler:^(MKNetworkOperation *operation) {
NSLog(@"[operation responseData]-->>%@", [operation responseString]);
responseJSON=[NSJSONSerialization JSONObjectWithData:[operation responseData] options:kNilOptions error:&error];
if(error) {
NSLog(@"JSONSerialization failed! - error: %@", error);
};
error=nil;
} errorHandler:^(MKNetworkOperation *errorOp, NSError* err) {
error=err;
}];
[engine enqueueOperation:op];
while(!error&&!responseJSON){}
if (error) {
NSLog(@"MKNetwork request error : %@", error);
return nil;
}
if(responseJSON){
NSLog(@"JSONSerialization successed! - responseJSON: %@", responseJSON);
}
return responseJSON;
}
NSDictionary *params=[NSDictionary dictionaryWithObjectsAndKeys:@"admin",@"userName", @"123",@"password", nil];
NSDictionary *responseDict = [self getDataFromURL:@"/login" params:params];
下载文件：
[cpp] view plaincopy
+(MKNetworkOperation*) downloadFatAssFileFrom:(NSString*) remoteURL toFile:(NSString*) filePath {
MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:@"127.0.0.1:5558" customHeaderFields:nil];
MKNetworkOperation *op = [engine operationWithURLString:remoteURL
params:nil
httpMethod:@"GET"];
[op addDownloadStream:[NSOutputStream outputStreamToFileAtPath:filePath
append:YES]];
[engine enqueueOperation:op];
return op;
}
+(void)testDownload{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cachesDirectory = [paths objectAtIndex:0];
NSString *downloadPath = [cachesDirectory stringByAppendingPathComponent:@"DownloadedFile.pdf"];
MKNetworkOperation *downloadOperation=[HttpManager downloadFatAssFileFrom:@"http://127.0.0.1:5558/QQ"
toFile:downloadPath];
[downloadOperation onDownloadProgressChanged:^(double progress) {
//下载进度
NSLog(@"download progress: %.2f", progress*100.0);
}];
//事件处理
[downloadOperation addCompletionHandler:^(MKNetworkOperation* completedRequest) {
NSLog(@"download file finished!");
} errorHandler:^(MKNetworkOperation *errorOp, NSError* err) {
NSLog(@"download file error: %@", err);
}];
}
上传文件：
[cpp] view plaincopy
+(MKNetworkOperation*) uploadImageFromFile:(NSString*) filePath mimeType:(NSString *)fileType{
MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:@"127.0.0.1:5558" customHeaderFields:nil];
MKNetworkOperation *op = [engine operationWithPath:@"upload"
params:[NSDictionary dictionaryWithObjectsAndKeys:
@"admin", @"username",
@"123", @"password",nil]
httpMethod:@"POST"];
[op addFile:filePath forKey:@"media" mimeType:fileType];
// setFreezable uploads your images after connection is restored!
[op setFreezable:YES];
[op addCompletionHandler:^(MKNetworkOperation* completedOperation) {
NSString *responseString = [completedOperation responseString];
NSLog(@"server response: %@",responseString);
} errorHandler:^(MKNetworkOperation *errorOp, NSError* err){
NSLog(@"Upload file error: %@", err);
}];
[engine enqueueOperation:op];
return op;
}
+(void)testUpload{
NSString *uploadPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"SampleImage.jpg"];
// NSData *myData = [NSData dataWithContentsOfFile:uploadPath];
// NSLog(@">>>>>>>>%@",myData);
MKNetworkOperation *uploadOperation = [HttpManager uploadImageFromFile:uploadPath mimeType:@"jpg"];
[uploadOperation onUploadProgressChanged:^(double progress) {
// 上传进度
DLog(@"Upload file progress: %.2f", progress*100.0);
}];
}
上传文件时服务器端程序(Node.Js):
[javascript] view plaincopy
var express = require('express')
,fs=require('fs');
var app = module.exports = express.createServer();
// Configuration
app.configure(function(){
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
});
// Routes
app.post('/upload', function(req, res) {
console.log(req);
var tmp_path = req.files.media.path; // 获得文件的临时路径
var target_path = './'+req.files.media.name;// 指定文件上传后的目录
fs.rename(tmp_path, target_path, function(err) { // 移动文件
if (err) throw err;
fs.unlink(tmp_path, function() {// 删除临时文件夹文件,
if (err) throw err;
res.send({server:'success'});
res.end();
});
});
});
app.listen(5558);
console.log("Express server listening on port %d in %s mode", app.address().port, app.settings.env);
