这儿的需求为两个固定的图片数组,可以根据需要进行修改
#FileUpLoad.h
/** * 上传带图片的内容，允许多张图片上传（URL）POST
*
* @param url 传url
* @param images 要上传的图片数组（注意数组内容需是图片）
* @param parameter 图片数组对应的参数 可以为nil
* @param parameters 其他参数字典 可以为nil
* @param succeedBlock 成功的回调
* @param failedBlock 失败的回调 */

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
//以下三项manager的属性根据需要进行配置 // manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/json"];
manager.requestSerializer.timeoutInterval = 10;

//根据当前系统时间生成图片名称

//习性文件数组

}
压缩图片
//压缩图片至100k以下
- (NSData *)imageData:(UIImage *)myimage{
NSData *data = UIImageJPEGRepresentation(myimage, 1.0);
if (data.length>100*1024) {
if (data.length>1024*1024) {//1M以及以上
data = UIImageJPEGRepresentation(myimage, 0.1);
} else if (data.length>512*1024) {//0.5M-1M
data = UIImageJPEGRepresentation(myimage, 0.5);
} else if (data.length>200*1024) {//0.25M-0.5M
data = UIImageJPEGRepresentation(myimage, 0.9);
}
}
return data;
}
调用
NSDictionary *paramDic = @{@"id":self.plantDetailModel.id, @"name":nameAndStatusModel.name, @"typeId":nameAndStatusModel.statusID, @"shapeDesc":infoModelOne.describe, @"applyDesc":infoModelTwo.describe};
NSArray *imags = @[infoModelOne.imageArr, infoModelTwo.imageArr];
NSArray *desc = @[@"shapeFileGroup", @"applyFileGroup"];
FileUpLoad *file = [[FileUpLoad alloc] init];
[file startMultiPartUploadTaskWithURL:[NSString stringWithFormat:@"%@%@",MAINURL, URL] imagesArray:imags parameterOfimages:desc parametersDict:paramDic succeedBlock:^(NSDictionary *dict) {
NSLog(@"dict = %@", dict);
} failedBlock:^(NSError *error) {
NSLog(@"error = %@", error);
}];
