iOS|iOS 上传图片 file格式 + 压缩图片
之前用OSS直接上传 在重新上报URL 看到file格式上传有点蒙蔽
- (void)uploadImgFile:(UIImage *)imageFile result:(void(^)(BOOL succeed, NSDictionary *dic))complete{AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
NSString *url = [NSString stringWithFormat:@"%@%@",root,uploadPicture];
[manager POST:url parameters:nil constructingBodyWithBlock:^(id_Nonnull formData) {NSData *data = [self imageZipToData:imageFile];
User *user = [SaveObject getModelWithKey:@"user"];
NSString *fileStr = [NSString stringWithFormat:@"%@%@.png",user.ID, [self getTimeNow]];
##formDataname:你的入参字典的key
[formData appendPartWithFileData:data name:@"file" fileName:fileStr mimeType:@"image/png"];
} progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id_Nullable responseObject) {NSLog(@"成功");
NSDictionary *result = responseObject;
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSString *success = [NSString stringWithFormat:@"%@", result[@"success"]];
if ([success isEqualToString:@"1"]) {complete(YES, result);
} else {NSString *errorsStr = result[@"errorDesc"];
[SimpleAlertView showWithState:errorsStr];
complete(NO, nil);
}} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"失败");
[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
NSDictionary *userinfo = error.userInfo;
NSString *errorsStr = [[NSString alloc] initWithData:userinfo[@"com.alamofire.serialization.response.error.data"]encoding:NSUTF8StringEncoding];
NSLog(@"请求失败:%@", errorsStr);
if (errorsStr.length > 0) {
[SimpleAlertView showWithState:errorsStr];
}else{
complete(NO, nil);
}}];
}
图片名字的随机数
/**
*返回当前时间
*/
- (NSString *)getTimeNow
{
NSString* date;
NSDateFormatter * formatter = [[NSDateFormatter alloc ] init];
[formatter setDateFormat:@"YYYYMMddhhmmss"];
date = [formatter stringFromDate:[NSDate date]];
//取出个随机数
int last = arc4random() % 10000;
NSString *timeNow = [[NSString alloc] initWithFormat:@"%@-%i", date,last];
NSLog(@"%@", timeNow);
return timeNow;
}
压缩图片
/**
*压缩图片
*/
- (NSData *)imageZipToData:(UIImage *)newImage{NSData *data = https://www.it610.com/article/UIImageJPEGRepresentation(newImage, 1.0);
if (data.length> 500 * 1024) {if (data.length>1024 * 1024) {//1M以及以上data = https://www.it610.com/article/UIImageJPEGRepresentation(newImage, 0.5);
}else if (data.length>512*1024) {//0.5M-1Mdata=https://www.it610.com/article/UIImageJPEGRepresentation(newImage, 0.6);
}else if (data.length>200*1024) { //0.25M-0.5Mdata=https://www.it610.com/article/UIImageJPEGRepresentation(newImage, 0.9);
}
}
return data;
}扩展
我的报讯信息是：reason: 'Invalid type in JSON write (UIImage)
网上查了下,能够转换为json字符串的对象必须具有如下属性:
顶层对象必须是NSArray或者NSDictionary
所有的对象必须是NSString/NSNumber/NSArray/NSDictionary/NSNull的实例
所有NSDictionary的key必须是NSString类型
数字对象不能是非数值或无穷;
相关报错信息： reason: 'Invalid type in JSON write (NSConcreteMutableData)
【iOS|iOS 上传图片 file格式 + 压缩图片】[iOS]将含有NSData数据的数组转化为json字符串报错:reason: 'Invalid type in JSON write (NSConcreteMutableData)
