iOS uploads with ASIHTTPRequest

1. Create a single View project, import the ASIHTTPRequest library, import the Mobilecoreservices, Cfnetwork, SystemConfiguration, and libz1.2.5.dylib four system libraries

2. Randomly import a picture, such as Haoyou.png

3.viewcontroller.h

?

1 2 3 4 5 6

#import <uikit uikit.h="">#import "ASIHTTPRequest.h"#import "ASIFormDataRequest.h"@interface ViewController : UIViewController @property (nonatomic, copy)NSString *m_auth;@end</asihttprequestdelegate></uikit>

4.VIEWCONTROLLER.M Add two buttons

?

1 2 3 4 5 6 7 8 9 Ten One A - - the

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

5. Two ways to implement login and upload

?

1 2 3 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

- (void)login {    NSURL *url = [NSURL URLWithString:@"..."];//此处省略请求url    //请求    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];    request.tag = 10;    request.delegate = self;    [request startAsynchronous];} - (void)upload {    NSURL* url = [NSURL URLWithString:@"..."];//此处省略请求url    UIImage* img = [UIImage imageNamed:@"haoyou.png"];    NSData* data = UIImagePNGRepresentation(img);    //ASIFormDataRequest请求是post请求，可以查看其源码    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"];//如果有路径，上传文件    [request setData:data  withFileName:@"tmp.png" andContentType:@"image/png" forKey:@"headimage"];//               数据                文件名,随便起                 文件类型            设置key    [request startAsynchronous];}

6. Implementing the Agreement

?

1 2 3 4 5 6 7 8 9 Ten One A - -

- (void)requestFailed:(ASIHTTPRequest *)request {    NSLog(@"请求失败");} - (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);    }}
