上传照片的两种方式
第一种：以文件流的形式上传图片。
formDate 设置数据name：@“改为传给后台的参数名”
AFHTTPSessionManager*manager = [AFHTTPSessionManagermanager];
//接收类型不一致请替换一致text/html或别的manager.responseSerializer.acceptableContentTypes= [NSSetsetWithObjects:@"application/json",
@"text/html",
@"image/jpeg",
@"image/png",
@"application/octet-stream",
@"text/json",
nil];
//AppDelegate*myDelegate = (AppDelegate*)[[UIApplicationsharedApplication]delegate];
//NSDictionary*dic =@{@"id":myDelegate.userId};
NSURLSessionDataTask*task = [managerPOST:urlparameters:dicconstructingBodyWithBlock:^(id_NonnullformData) {
NSData*imageDatas = imageData;
NSDateFormatter*formatter = [[NSDateFormatteralloc]init];
formatter.dateFormat=@"yyyyMMddHHmmss";
NSString*str = [formatterstringFromDate:[NSDatedate]];
NSString*fileName = [NSStringstringWithFormat:@"%@.jpg", str];
//上传的参数(上传图片，以文件流的格式)
[formDataappendPartWithFileData:imageDatas
name:@"photo"
fileName:fileName
mimeType:@"image/jpeg"];
}progress:^(NSProgress*_NonnulluploadProgress) {
//打印下上传进度
NSLog(@"上传进度");
NSLog(@"%@",uploadProgress);
}success:^(NSURLSessionDataTask*_Nonnulltask,id_NullableresponseObject) {
//上传成功
NSLog(@"上传成功");
NSLog(@"%@",responseObject);
}failure:^(NSURLSessionDataTask*_Nullabletask,NSError*_Nonnullerror) {
//上传失败
NSLog(@"上传失败");
}];
第二种：将image转成NSData，在进行base64加密上传。
- (void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info {
NSString*mediaType = [infoobjectForKey:UIImagePickerControllerMediaType];
UIImage*image = [[UIImagealloc]init];
if([mediaTypeisEqualToString:@"public.image"]){
image = [infoobjectForKey:@"UIImagePickerControllerOriginalImage"];
[_headimagesetImage:image];
// [_changeBtn setImage:image forState:UIControlStateNormal];
NSData*data;
if(UIImagePNGRepresentation(image) ==nil) {
data =UIImageJPEGRepresentation(image,1);
}else{
data =UIImageJPEGRepresentation(image,0.001); //压缩图片，方便上传
}
// //获取文件路径
NSString*imageString = [database64EncodedStringWithOptions:0];
转成base64字符串imageString，再传给给后台，在传参中需要添加图片的类型（@“png”或@“jpg”等）
}
[pickerdismissViewControllerAnimated:YEScompletion:nil];
}
