iOS 使用AFN 進行單圖和多圖上傳
圖片上傳時必要將圖片進行壓縮,不然會上傳失敗
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撥
completion(responseObject,nil);
} failure:^(AFHTTPRequestOperation * _Nonnull operation, NSError * _Nonnull error) {
//上傳圖片失敗執行回撥
completion(nil,error);
}];
2.多圖上傳
多圖上傳和單圖上傳區別在於檔名稱
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);
}];
