AFNetworking上传图片
基本代码如下
[manager POST:@"" parameters:nil constructingBodyWithBlock:^(id_Nonnull formData) {UIImage *image =[UIImage imageNamed:@"image"];
//png和jpeg的压缩
NSData *data = https://www.it610.com/article/UIImagePNGRepresentation(image);
//NSData *data = UIImageJPEGRepresentation(image, 0.1);
//采用时间来防止名字重复
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
formatter.dateFormat = @"yyyyMMddHHmmss";
NSString *str = [formatter stringFromDate:[NSDate date]];
NSString *fileName = [NSString stringWithFormat:@"%@.png", str];
//上传
/*
1. name:指服务器获取该图片所用的“键”的名字
2. fileName:文件在服务器上保存的名字
*/
[formData appendPartWithFileData:data name:@"file" fileName:fileName mimeType:@"image/png"];
} progress:^(NSProgress * _Nonnull uploadProgress) {
NSLog(@"当前进度:%lf / 总进度:%lf",uploadProgress.completedUnitCount,uploadProgress.totalUnitCount);
} success:^(NSURLSessionDataTask * _Nonnull task, id_Nullable responseObject) {
NSLog(@"success");
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"failure");
}];
