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);
