MKNetworkKit的使用

 

链接：http://blog.csdn.net/lookyou111/article/details/26450663

 

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];

    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) {
    NSLog(@"[operation responseData]-->>%@", [operation responseString]);
}errorHandler:^(MKNetworkOperation *errorOp, NSError* err) {
    NSLog(@"MKNetwork request error : %@", [err localizedDescription]);
}];
[engine enqueueOperation:op];

    https方式：

#define serverHost               @"192.168.1.84:5558"

- (NSDictionary *)getDataFromURL:(NSString *)Path params:(NSDictionary *)data
{
    NSLog(@"MKNetwork request URL:  %@%@   
 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：

+(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：

+(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):

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.e
