图片上传时必要将图片进行压缩,不然会上传失败

1.单张图上传

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; [manager POST:urlString parameters:params constructingBodyWithBlock:^(id_Nonnull formData) { //使用日期生成图片名称 NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss"; NSString *fileName = [NSString stringWithFormat:@"%@.png",[formatter stringFromDate:[NSDate date]]]; [formData appendPartWithFileData:imageData name:@"uploadFile" fileName:fileName mimeType:@"image/png"]; } success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { //上传图片成功执行回调 completion(responseObject,nil); } failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) { //上传图片失败执行回调 completion(nil,error); }];

2.多图上传

多图上传和单图上传区别在于文件名称

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; [manager POST:urlString parameters:params constructingBodyWithBlock:^(id_Nonnull formData) { NSInteger imgCount = 0; for (NSData *imageData in imageDatas) { NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss:SSS"; NSString *fileName = [NSString stringWithFormat:@"%@%@.png",[formatter stringFromDate:[NSDate date]],@(imgCount)]; [formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"uploadFile%@",@(imgCount)] fileName:fileName mimeType:@"image/png"]; imgCount++; } } success:^(AFHTTPRequestOperation * _Nonnull operation, id _Nonnull responseObject) { completion(responseObject,nil); } failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) { completion(nil,error); }];
