HTTP请求
NSString *urlStr = @"http://api.openweathermap.org/data/2.5/forecast/city?id=524901&APPID=bf791ba9eeca14dd22823b4c21ce7e2d";
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
// 设置回复内容信息
manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes
setByAddingObject:@"text/html"];
[manager GET:urlStr
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
//请求正文数据
//NSLog(@"%@",responseObject);
//请求头部信息(我们执行网络请求的时候给服务器发送的信息)
//NSLog(@"%@",operation.request.allHTTPHeaderFields);
//服务器返回的包的头部信息
NSLog(@"%@",operation.response);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"%@",error);
}];
请求方法
(GET、POST等)
// 执行POST请求，需要将参数写在parameter处，而不能如同get方法一样直接写在地址栏
[manager POST:@"http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx/getMobileCodeInfo"
parameters:@{@"mobileCode" : @"15910514636",
@"userID" : @""}
success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"%@", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"%@", error);
}];
请求头
(HttpHeaderFields)
//请求头部信息(我们执行网络请求的时候给服务器发送的信息)
NSLog(@"%@",operation.request.allHTTPHeaderFields);
请求正文 (数据)
问号后的字符串，使用get方法是可以在地址栏中看见的
NSString *urlStr = @"http://api.openweathermap.org/data/2.5/forecast/city?id=524901&APPID=bf791ba9eeca14dd22823b4c21ce7e2d";
序列化
采用不同的序列化格式，得到不同的response结果
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
// 请求的序列化
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
// 回复序列化
//responseObject就变成二进制文件
manager.responseSerializer[AFHTTPResponseSerializer serializer];
//responseObject就变成JSON格式
manager.responseSerializer = [AFJSONResponseSerializer serializer];
//responseObject成为xml格式
manager.responseSerializer = [AFXMLParserResponseSerializer serializer];
上传文件
// 获取数据
UIImage *image = [UIImage imageNamed:@"demo"];
NSData *dataObj = UIImageJPEGRepresentation(image, 1.0);
// 参数
NSDictionary *paras = @{@"ContactName" : @"Lilis",
@"ContactPhoneNumber" : @"15910514635",
@"LoseDetail" : @"...",
@"address" : @"",
@"gender" : @"2",
@"verify" : @"012460"};
[Networking UploadDataWithUrlString:BASE_URL // 请更换网址
parameters:paras
timeoutInterval:nil
requestType:HTTPRequestType
responseType:JSONResponseType
constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
// 构造数据的地方
[formData appendPartWithFileData:dataObj name:@"upload" fileName:@"image1.jpg" mimeType:@""];
[formData appendPartWithFileData:dataObj name:@"upload" fileName:@"image2.jpg" mimeType:@""];
}
success:^(AFHTTPRequestOperation *operation, id responseObject) {
// 请求头
NSLog(@"%@", operation.request.allHTTPHeaderFields);
// 服务器回复的头
NSLog(@"%@", operation.response);
NSLog(@"%@", responseObject);
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];
断点下载
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://c.hiphotos.baidu.com/image/pic/item/f3d3572c11dfa9ec78e256df60d0f703908fc12e.jpg"]];
AFDownloadRequestOperation *operation = [[AFDownloadRequestOperation alloc] initWithRequest:request
fileIdentifier:@"fuck.jpg"
targetPath:[NSHomeDirectory() stringByAppendingPathComponent:@"/Library/Caches/fuck.jpg"]
shouldResume:YES];
operation.shouldOverwrite = YES;
// 开始下载
[operation start];
// 2s后暂停
[GCDQueue executeInMainQueue:^{
NSLog(@"暂停");
[operation pause];
} afterDelaySecs:2.f];
// 4s后继续恢复
[GCDQueue executeInMainQueue:^{
NSLog(@"开始");
[operation resume];
} afterDelaySecs:4.f];
// 查看下载进度
[operation setProgressiveDownloadProgressBlock:^(AFDownloadRequestOperation *operation, NSInteger bytesRead, long long totalBytesRead, long long totalBytesExpected, long long totalBytesReadForFile, long long totalBytesExpectedToReadForFile) {
CGFloat percent = (float)totalBytesReadForFile / (float)totalBytesExpectedToReadForFile;
NSLog(@"百分比:%.3f%% %ld %lld %lld %lld", percent * 100, (long)bytesRead, totalBytesRead, totalBytesReadForFile, totalBytesExpectedToReadForFile);
}];
// 结束block
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"下载成功 %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"下载失败 %@", error);
}];
监听网络
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// 开启网络指示器
[[AFNetworkActivityIndicatorManager sharedManager] setEnabled:YES];
NSURL *url = [NSURL URLWithString:@"http://baidu.com"];
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:url];
NSOperationQueue *operationQueue = manager.operationQueue;
[manager.reachabilityManager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status) {
case AFNetworkReachabilityStatusReachableViaWWAN:
case AFNetworkReachabilityStatusReachableViaWiFi:
[operationQueue setSuspended:NO];
NSLog(@"有网络");
break;
case AFNetworkReachabilityStatusNotReachable:
default:
[operationQueue setSuspended:YES];
NSLog(@"无网络");
break;
}
}];
// 开始监听
[manager.reachabilityManager startMonitoring];
return YES;
}
