iOS上传图片和上传语音

一、上传多张图片

备注:支持上传不同类型的图片(举例:imageDatas图片数组最后一项image元素对应不同参数名)

// 上传图片
- (void)postDataWithUrl:(NSString *)url params:(NSMutableDictionary *)params imageDatas:(NSArray *)images success:(void (^)(id response))success failure:(void (^)(NSError *error))failure
{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager.responseSerializer setAcceptableContentTypes:[NSSet setWithObjects:@"application/json",@"text/html",@"text/javascript",@"text/xml",@"text/plain",nil]];
    [manager POST:url parameters:params constructingBodyWithBlock:^(id  _Nonnull formData) {
        for (UIImage *image in images) {
            // 图片太大会上传不到服务器上面去
            NSData *imageData = UIImageJPEGRepresentation(image, 0.1);;
            // 在网络开发中,上传文件时,是文件不允许被覆盖,文件重名
            // 要解决此问题,
            // 可以在上传时使用当前的系统事件作为文件名
            NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
            // 设置时间格式
            formatter.dateFormat = @"yyyyMMddHHmmss";
            NSString *str = [formatter stringFromDate:[NSDate date]];
            NSString *fileName = [NSString stringWithFormat:@"%@.png", str];
            /*
             此方法参数
             1. 要上传的[二进制数据]
             2. 对应网站上[upload.php中]处理文件的[字段"file"]
             3. 要保存在服务器上的[文件名]
             4. 上传文件的[mimeType]
             */
            NSUInteger index = [images indexOfObject:image];
            if (index == images.count-1) {
                // 上传位置图片data
                [formData appendPartWithFileData:imageData name:@"posfile" fileName:fileName mimeType:@"image/png"];
            } else {
                [formData appendPartWithFileData:imageData name:@"file" fileName:fileName mimeType:@"image/png"];
            }
        }
    } progress:^(NSProgress * _Nonnull uploadProgress) {
        NSLog(@"uploadProgress = %@",uploadProgress);
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        success(responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        failure(error);
    }];
}

二、上传语音文件

备注:支持上传图片、语音同时上传;根据自己的需求定制化调整代码即可

// 上传语音
- (void)POSTOneAmrWithUrl:(NSString *)url params:(NSMutableDictionary *)params voiceName:(NSString *)fileName AmrDatas:(NSData *)amr imageDatas:(NSArray *)images success:(void (^)(id response))success failure:(void (^)(NSError *error))failure
{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager.responseSerializer setAcceptableContentTypes:[NSSet setWithObjects:@"application/json",@"text/html",@"text/javascript",@"text/xml",@"text/plain",nil]];
    [manager POST:url parameters:params constructingBodyWithBlock:^(id  _Nonnull formData) {
        
        [formData appendPartWithFileData:amr name:@"voicefile" fileName: [NSString stringWithFormat:@"%@.mp3", fileName] mimeType:@"amr/mp3/wmr"];
        
        for (UIImage *image in images) {
            // 图片太大会上传不到服务器上面去
            NSData *imageData = UIImageJPEGRepresentation(image, 0.1);;
            // 在网络开发中,上传文件时,是文件不允许被覆盖,文件重名
            // 要解决此问题,
            // 可以在上传时使用当前的系统事件作为文件名
            NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
            // 设置时间格式
            formatter.dateFormat = @"yyyyMMddHHmmss";
            NSString *str = [formatter stringFromDate:[NSDate date]];
            NSString *fileName = [NSString stringWithFormat:@"%@.png", str];
            /*
             此方法参数
             1. 要上传的[二进制数据]
             2. 对应网站上[upload.php中]处理文件的[字段"file"]
             3. 要保存在服务器上的[文件名]
             4. 上传文件的[mimeType]
             */
            NSUInteger index = [images indexOfObject:image];
            if (index == images.count-1) {
                // 上传位置图片data
                [formData appendPartWithFileData:imageData name:@"posfile" fileName:fileName mimeType:@"image/png"];
            } else {
                [formData appendPartWithFileData:imageData name:@"file" fileName:fileName mimeType:@"image/png"];
            }
        }
    } progress:^(NSProgress * _Nonnull uploadProgress) {
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        success(responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        failure(error);
    }];
}
