AFURLSessionManager 上传下载使用代码说明
1、下载CreatingaDownloadTask
NSURLSessionConfiguration*configuration=[NSURLSessionConfigurationdefaultSessionConfiguration];
AFURLSessionManager*manager=[[AFURLSessionManageralloc]initWithSessionConfiguration:configuration];
NSURL*URL=[NSURLURLWithString:@"http://example.com/download.zip"];
NSURLRequest*request=[NSURLRequestrequestWithURL:URL];
NSURLSessionDownloadTask*downloadTask=[managerdownloadTaskWithRequest:requestprogress:nildestination:^NSURL*(NSURL*targetPath,NSURLResponse*response){
NSURL*documentsDirectoryURL=[[NSFileManagerdefaultManager]URLForDirectory:NSDocumentDirectoryinDomain:NSUserDomainMaskappropriateForURL:nilcreate:NOerror:nil];
return[documentsDirectoryURLURLByAppendingPathComponent:[responsesuggestedFilename]];
}completionHandler:^(NSURLResponse*response,NSURL*filePath,NSError*error){
NSLog(@"Filedownloadedto:%@",filePath);
}];
[downloadTaskresume];
2、上传CreatinganUploadTask
NSURLSessionConfiguration*configuration=[NSURLSessionConfigurationdefaultSessionConfiguration];
AFURLSessionManager*manager=[[AFURLSessionManageralloc]initWithSessionConfiguration:configuration];
NSURL*URL=[NSURLURLWithString:@"http://example.com/upload"];
NSURLRequest*request=[NSURLRequestrequestWithURL:URL];
NSURL*filePath=[NSURLfileURLWithPath:@"file://path/to/image.png"];
NSURLSessionUploadTask*uploadTask=[manageruploadTaskWithRequest:requestfromFile:filePathprogress:nilcompletionHandler:^(NSURLResponse*response,idresponseObject,NSError*error){
if(error){
NSLog(@"Error:%@",error);
}else{
NSLog(@"Success:%@%@",response,responseObject);
}
}];
[uploadTaskresume];
3、批量上传CreatinganUploadTaskforaMulti-PartRequest,withProgress
NSMutableURLRequest*request=[[AFHTTPRequestSerializerserializer]multipartFormRequestWithMethod:@"POST"URLString:@"http://example.com/upload"parameters:nilconstructingBodyWithBlock:^(idformData){ [formDataappendPartWithFileURL:[NSURLfileURLWithPath:@"file://path/to/image.jpg"]name:@"file"fileName:@"filename.jpg"mimeType:@"image/jpeg"error:nil]; }error:nil]; AFURLSessionManager*manager=[[AFURLSessionManageralloc]initWithSessionConfiguration:[NSURLSessionConfigurationdefaultSessionConfiguration]]; NSURLSessionUploadTask*uploadTask; uploadTask=[manager uploadTaskWithStreamedRequest:request progress:^(NSProgress*_NonnulluploadProgress){ //Thisisnotcalledbackonthemainqueue. //YouareresponsiblefordispatchingtothemainqueueforUIupdates dispatch_async(dispatch_get_main_queue(),^{ //Updatetheprogressview [progressViewsetProgress:uploadProgress.fractionCompleted]; }); } completionHandler:^(NSURLResponse*_Nonnullresponse,id_NullableresponseObject,NSError*_Nullableerror){ if(error){ NSLog(@"Error:%@",error); }else{ NSLog(@"%@%@",response,responseObject); } }]; [uploadTaskresume];
4、数据任务CreatingaDataTask
NSURLSessionConfiguration*configuration=[NSURLSessionConfigurationdefaultSessionConfiguration];
AFURLSessionManager*manager=[[AFURLSessionManageralloc]initWithSessionConfiguration:configuration];
NSURL*URL=[NSURLURLWithString:@"http://httpbin.org/get"];
NSURLRequest*request=[NSURLRequestrequestWithURL:URL];
NSURLSessionDataTask*dataTask=[managerdataTaskWithRequest:requestcompletionHandler:^(NSURLResponse*response,idresponseObject,NSError*error){
if(error){
NSLog(@"Error:%@",error);
}else{
NSLog(@"%@%@",response,responseObject);
}
}];
[dataTaskresume];
5、请求参数设置RequestSerialization
RequestserializerscreaterequestsfromURLstrings,encodingparametersaseitheraquerystringorHTTPbody.
NSString*URLString=@"http://example.com";
NSDictionary*parameters=@{@"foo":@"bar",@"baz":@[@1,@2,@3]};
