摘要: ios MKNetworkKit 的使用 转载http://blog.csdn.net/marujunyy/article/details/8495810
目录:[ - ]
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!!!
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];<span style="font-family: SimSun;"> </span>
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

- 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];

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);
