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:
- 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];"font-family: SimSun;">
POST请求:
- 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) {

- // 在请求中添加证书
- op.clientCertificate = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"client.p12"];

- // 当服务器端证书不合法时是否继续访问
- op.shouldContinueWithInvalidCertificate=YES;
- [op addCompletionHandler:^(MKNetworkOperation *operation) {

上传文件时服务器端程序(Node.Js):
[javascript] view plain copy
- 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);
