最近项目中要求能够上传图片和日志(可恶!你怎么不要求上传视频呢!),用的是老牌的ZipArchive,居然跳了几次坑,特来记录下来免得下次又忘记了=。=
下面这份就是全部的压缩代码了(上传的是最多五张图片):
NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
/** 新建文件夹路径*/
NSString *imagePath = [path stringByAppendingPathComponent:@"feedBackImages"];
NSFileManager *photoFileManager = [NSFileManager defaultManager];
/** 判断该路径存不存在,若不存在就建立这个文件夹*/
if (![photoFileManager fileExistsAtPath:imagePath]) {
[photoFileManager createDirectoryAtPath:imagePath withIntermediateDirectories:YES attributes:nil error:nil];
}
/** 检查文件夹有没有内容,若有则清空*/
NSDirectoryEnumerator *dirEnum = [photoFileManager enumeratorAtPath:imagePath];
NSString *fileName = @"";
while (fileName = [dirEnum nextObject]) {
[photoFileManager removeItemAtPath:[NSString stringWithFormat:@"%@/%@", imagePath, fileName] error:nil];
}
NSUInteger count = self.choosePictureView.imageArray.count - 1;
NSUInteger length = 0;
for (int i = 0; i < count; i++) {
UIImage *photoImage = self.choosePictureView.imageArray[i];
/** 压缩用户选择的图片*/
NSData *dataImage = UIImageJPEGRepresentation(photoImage, 0.3);
length += dataImage.length;
if (length > 5 * pow(1024, 2)) {
HintView *hintView = [[HintView alloc]initWith:LocatizedStirngForkey(@"上传图片过大")];
[hintView showInView];
return;
}
UIImage *choosePhoto = [UIImage imageWithData:dataImage];
[self.choosePhotoArray addObject:choosePhoto];
NSString *pictureNew = [NSString stringWithFormat:@"/picImage_%d.jpeg",i];
/** 存入每张照片*/
NSString *NewPhotoPath = [imagePath stringByAppendingString:pictureNew];
[photoFileManager createFileAtPath:NewPhotoPath contents:dataImage attributes:nil];
}
ZipArchive *zip =[[ZipArchive alloc] init];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *rootPathStr = ([paths count] > 0) ? paths[0] : nil;
/** 图片压缩包名*/
NSString *uploadFileName = @"feedbackPictureUpload.zip";
NSString *photoZip = [rootPathStr stringByAppendingPathComponent:uploadFileName];
/** 创建zip文件*/
BOOL ret = [zip CreateZipFile2:photoZip];
/** 遍历文件夹,将文件夹中的文件添加到压缩文件包中*/
dirEnum = [photoFileManager enumeratorAtPath:imagePath];
while ((fileName = [dirEnum nextObject]) != nil) {
ret = [zip addFileToZip:[imagePath stringByAppendingPathComponent:fileName] newname:fileName];
}
/** 确认文件是否已经压缩完成*/
if ([zip CloseZipFile2]) {
[self feedbackPictureUpload:uploadFileName withFilePath:photoZip andFeedbackId:feedBackId];
}
首先说一下我跳进去的坑吧:
1、第一个是最后我居然没有确认文件是不是已经压缩完成,就直接调用了上传的方法,服务器那边虽然能够收到压缩包,但是一直解压失败,提示文件损坏,这还是最后比较手机内生成的ZIP包和服务器那边收到的ZIP包大小的时候发现的= =!
最后提示![zip CloseZipFile2]!千万别忘了!
2、第二个就是文件的contentType了,貌似图片和别的contentType不一样,需要在AFNManager里加上multipart/form-data类型,服务器那边才收的到
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"multipart/form-data",@"text/plain", nil];
好了,就这么多了,其他的坑我倒是没遇到,等遇到了再来更新吧O.O
