Request failed: request too larg
服务器请求限制:
iis默认只有200k
跟后台反应一下。iis默认200K限制。ngnix默认1M,apache默认2M。
图片压缩:(写了一个分类方法)
@implementation UIImage (Compress)
/*
* 压缩图片至目标尺寸
*
* @param targetWidth 图片最终尺寸的宽
*
* @return 返回按照源图片的宽、高比例压缩至目标宽、高的图片
*/
-(UIImage *)compressImageToTargetWidth:(CGFloat)targetWidth{
CGSize imageSize = self.size;
CGFloat width = imageSize.width;
CGFloat height = imageSize.height;
CGFloat targetHeight = (targetWidth / width) * height;
UIGraphicsBeginImageContext(CGSizeMake(targetWidth, targetHeight));
[self drawInRect:CGRectMake(0, 0, targetWidth, targetHeight)];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return newImage;
}
图片转二进制压缩:(注意UIImageJPEGRepresentation压缩是有限度的,当图片比较大时,最低压缩到200k级别,此后无论压缩值设置多小都不能再进步压缩)
UIImage *icon = iconArr[i][@"icon"];
NSString *name = iconArr[i][@"name"];
object.data = UIImageJPEGRepresentation(icon,0.8);//0.8为压缩值
一般上传多张图片,如果图片张数比较少,请求一次接口,将一组图片传给服务器。如果图片张数比较多,用递归来多次请求接口,通过每次请求的返回参数(如上传的图片名),来判断该图片是否上传成功及是否所有图片上传完成。
