Question

我无法将多个图片上传到服务器。我正在使用以下代码进行上传：

-(void)upload {
 NSString *path=[NSString stringWithFormat:@"%@.php",webserviceURL];
 ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:path]];
 [request addPostValue:@"306" forKey:@"id"];

 for (int i= 0; i<[imageArray count]; i++) {
    NSData *imgData = UIImageJPEGRepresentation([imageArray objectAtIndex:i],1.0);
    NSDate *date....

     .....

    NSLog(@"dateString");//for getting different file name..

    [request addData:imgData withFileName:[NSString stringWithFormat:@"%@.jpg",dateString] 
    andContentType:@"image/jpeg" forKey:@"image"];
  }

 [request setDelegate:self]; 
 [request startAsynchronous];
}

使用此代码，我只能上传一张图片。如何使用相同的密钥上传多个图像？

请求：ASIFormDataRequest很老，作者没有更新。您应该切换到AFNetworking。

如果您使用PHP作为接收文件的后端，则应该能够发送文件数组。

NSData *imageToUpload = UIImageJPEGRepresentation([UIImage imageNamed:@"profile-image-placeholder"], 10);
AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://www.imthi.com"]];

NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"/info.php" parameters:nil constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
    [formData appendPartWithFileData: imageToUpload name:@"image[0]" fileName:@"temp.jpeg" mimeType:@"image/jpeg"];
    [formData appendPartWithFileData: imageToUpload name:@"image[1]" fileName:@"temp.jpeg" mimeType:@"image/jpeg"];
    [formData appendPartWithFileData: imageToUpload name:@"image[2]" fileName:@"temp.jpeg" mimeType:@"image/jpeg"];
}];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation * _operation, id responseObject) {
    NSString *response = [_operation responseString];
    NSLog(@"response: [%@]",response);
} failure:^(AFHTTPRequestOperation * _operation, NSError *error) {
    if([_operation.response statusCode] == 403){
        NSLog(@"Upload Failed");
        return;
    }
}];
[operation start];

诀窍是使用图像[0]，图像1，图像[2]等作为添加更多文件的关键。尝试更改代码，它也适用于您当前的库。

[request addData:imgData withFileName:[NSString stringWithFormat:@"%@.jpg",dateString] andContentType:@"image/jpeg" forKey:[NSString stringWithFormat:@"image[%d]",i]];

在你的PHP上你应该收到像这样的文件..

(
[image] => Array
    (
        [name] => Array
            (
                [0] => temp.jpeg
                [1] => temp.jpeg
                [2] => temp.jpeg
            )

        [type] => Array
            (
                [0] => image/jpeg
                [1] => image/jpeg
                [2] => image/jpeg
            )

        [tmp_name] => Array
            (
                [0] => /tmp/php4XsVR8
                [1] => /tmp/phpDBPzVO
                [2] => /tmp/phpu26eZu
            )

        [error] => Array
            (
                [0] => 0
                [1] => 0
                [2] => 0
            )

        [size] => Array
            (
                [0] => 2207
                [1] => 2207
                [2] => 2207
            )

    )
