iOS用ASIHttpRequest上傳

1.建立一個single view工程，匯入ASIHttpRequest庫，匯入MobileCoreServices、CFNetwork、SystemConfiguration和libz1.2.5.dylib四個系統庫

2.隨便匯入一張圖片，比如haoyou.png

3.ViewController.h

#import #import "ASIHTTPRequest.h"#import "ASIFormDataRequest.h"@interface ViewController : UIViewController @property (nonatomic, copy)NSString *m_auth;@end

4.ViewController.m 添加兩個按鈕

- (void)viewDidLoad {    [super viewDidLoad];    UIButton *loginBtn = [UIButton buttonWithType:UIButtonTypeRoundedRect];    loginBtn.frame = CGRectMake(100, 20, 120, 40);    [loginBtn setTitle:@"登入" forState:UIControlStateNormal];    [loginBtn addTarget:self action:@selector(login) forControlEvents:UIControlEventTouchUpInside];    [self.view addSubview:loginBtn];        UIButton *uploadBtn = [UIButton buttonWithType:UIButtonTypeRoundedRect];    uploadBtn.frame = CGRectMake(100, 80, 120, 40);    [uploadBtn setTitle:@"上傳" forState:UIControlStateNormal];    [uploadBtn   addTarget:self action:@selector(upload) forControlEvents:UIControlEventTouchUpInside];     [self.view addSubview:uploadBtn];}

5.實現login和upload兩個方法

- (void)login {    NSURL *url = [NSURL URLWithString:@"..."];//此處省略請求url    //請求    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];    request.tag = 10;    request.delegate = self;    [request startAsynchronous];}- (void)upload {    NSURL* url = [NSURL URLWithString:@"..."];//此處省略請求url    UIImage* img = [UIImage imageNamed:@"haoyou.png"];    NSData* data = UIImagePNGRepresentation(img);    //ASIFormDataRequest請求是post請求，可以查看其源碼    ASIFormDataRequest* request = [ASIFormDataRequest requestWithURL:url];    request.tag = 20;    request.delegate = self;    [request setPostValue:self.m_auth forKey:@"m_auth"];//    [request setFile:@"tabbar.png" forKey:@"haoyou"];//如果有路徑，上傳檔案    [request setData:data  withFileName:@"tmp.png" andContentType:@"image/png" forKey:@"headimage"];//               資料                檔案名稱,隨便起                 檔案類型            設定key    [request startAsynchronous];}

6.實現協議

- (void)requestFailed:(ASIHTTPRequest *)request {    NSLog(@"請求失敗");}- (void)requestFinished:(ASIHTTPRequest *)request {    if (request.tag == 10) {        NSDictionary * dic = [NSJSONSerialization JSONObjectWithData:request.responseData options:0 error:nil];        self.m_auth = [dic objectForKey:@"m_auth"];        NSLog(@"%@", self.m_auth);    }    if (request.tag == 20) {        NSLog(@"%@", request.responseString);    }}
