1. 简单的上传任务

// 上传文件- (void)uploadTask {    NSURL *url = [NSURL URLWithString:@"http://127.0.0.1/uploads/123.png"];    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];    request.HTTPMethod = @"put";    [request setValue:[self getAuth:@"admin" pwd:@"1"] forHTTPHeaderField:@"Authorization"];//    [request setValue:@"Basic YWRtaW46MQ==" forHTTPHeaderField:@"Authorization"];    // 本地文件    NSURL *fileUrl = [[NSBundle mainBundle] URLForResource:@"head1.png" withExtension:nil];    [[[NSURLSession sharedSession] uploadTaskWithRequest:request fromFile:fileUrl completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {        NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];        NSLog(@"%@", str);    }] resume];}// 获取授权的字符串- (NSString *)getAuth:(NSString *)name pwd:(NSString *)pwd {    // 拼字符串 admin:1    NSString *tmpStr = [NSString stringWithFormat:@"%@:%@",name,pwd];    // base64编码    tmpStr = [self base64Encode:tmpStr];    return [NSString stringWithFormat:@"Basic %@", tmpStr];}// base64编码- (NSString *)base64Encode:(NSString *)str {    NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];    return [data base64EncodedStringWithOptions:0];}

2. 监听进度的上传

#import "ViewController.h"@interface ViewController () 
     
      @property (nonatomic, strong) NSURLSession *session;@end@implementation ViewController// 懒加载- (NSURLSession *)session {    if (_session == nil) {        NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];        _session = [NSURLSession sessionWithConfiguration:config delegate:self delegateQueue:0];    }    return _session;}- (void)viewDidLoad {    [super viewDidLoad];}- (void)touchesBegan:(NSSet
      
        *)touches withEvent:(UIEvent *)event {    [self uploadTask];}// 上传文件，监听进度- (void)uploadTask {        NSURL *url = [NSURL URLWithString:@"http://127.0.0.1/uploads/123.png"];    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];    request.HTTPMethod = @"put";    [request setValue:[self getAuth:@"admin" pwd:@"1"] forHTTPHeaderField:@"Authorization"];    // 本地文件    NSURL *fileUrl = [[NSBundle mainBundle] URLForResource:@"head1.png" withExtension:nil];        [[self.session uploadTaskWithRequest:request fromFile:fileUrl completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {        NSString *str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];        NSLog(@"---%@", str);    }] resume];}#pragma mark - 上传进度代理方法// 上传进度- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didSendBodyData:(int64_t)bytesSent totalBytesSent:(int64_t)totalBytesSent totalBytesExpectedToSend:(int64_t)totalBytesExpectedToSend {    // 进度 = 已发送的 / 一共需要发送的    float process = totalBytesSent * 1.0 / totalBytesExpectedToSend;    NSLog(@"%f", process);}// 上传完成- (void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didCompleteWithError:(NSError *)error {    NSLog(@"上传完成");}// 获取授权的字符串- (NSString *)getAuth:(NSString *)name pwd:(NSString *)pwd {    // 拼字符串 admin:1    NSString *tmpStr = [NSString stringWithFormat:@"%@:%@",name,pwd];    // base64编码    tmpStr = [self base64Encode:tmpStr];    return [NSString stringWithFormat:@"Basic %@", tmpStr];}// base64编码- (NSString *)base64Encode:(NSString *)str {    NSData *data = [str dataUsingEncoding:NSUTF8StringEncoding];    return [data base64EncodedStringWithOptions:0];}@end
      
     

3. NSURLSessionConfiguration配置
