02-iOS 使用AFN 進行單圖和多圖上傳

//1.單張圖上傳

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    [manager POST:urlString parameters:params constructingBodyWithBlock:^(id_Nonnull formData) {

//使用日期生成圖片名稱

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss";

NSString *fileName = [NSString stringWithFormat:@"%@.png",[formatter stringFromDate:[NSDate date]]];

[formData appendPartWithFileData:imageData name:@"uploadFile" fileName:fileName mimeType:@"image/png"];

} success:^(AFHTTPRequestOperation * _Nonnull operation, id  _Nonnull responseObject) {

//上傳圖片成功執行回調

completion(responseObject,nil);

} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {

//上傳圖片失敗執行回調

completion(nil,error);

}];

2.多圖上傳

多圖上傳和單圖上傳區別在於文件名稱

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    [manager POST:urlString parameters:params constructingBodyWithBlock:^(id_Nonnull formData) {

NSInteger imgCount = 0;

for (NSData *imageData in imageDatas) {

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss:SSS";

NSString *fileName = [NSString stringWithFormat:@"%@%@.png",[formatter stringFromDate:[NSDate date]],@(imgCount)];

[formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"uploadFile%@",@(imgCount)] fileName:fileName mimeType:@"image/png"];

imgCount++;

}

} success:^(AFHTTPRequestOperation * _Nonnull operation, id  _Nonnull responseObject) {

completion(responseObject,nil);

} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {

completion(nil,error);

}];
