iphone下载图像与变量使用ASIHTTPRequest

问题描述

我陷入困境。

我将图像上传到服务器，没关系。
但是，当我尝试从服务器下载图像时，我想使用字符串变量获取图像。这里是我的php代码服务器端

  .... 
 
 echoimage_getting;; 
 $ fullPath = $ _POST ['download_image']; 
 echo file_get_contents（$ fullPath）; 
 
 .... 
  

如果我从我的服务器删除第一行[请求responseData]正常工作。
但是，我也想得到image_getting;因为我也在下载一些不同的类型。

如果我可以清除，iphone侧
当我说

$（$）$（$）$（$）$（$）$（$）$（$）$
NSLog（@％@，responseString）;

NSArray * resultResponseArray = [responseString componentsSeparatedByString：@;];
if（[[resultResponseArray objectAtIndex：0] isEqualToString：@image_getting]）
{
NSData * responseData = [request responseData];
UIImage * image = [UIImage imageWithData：aData];
.......
}
else if ...
....
}
/ pre>

正如你可以看到上面的回复数据也采取回声image_getting我如何拆分它。
我试图转换并拆分它们不起作用。

我应该说，我对php非常糟糕。

如果有人帮我，我将不胜感激。
感谢

编辑：解决方案Php端

 标题（'X-Return：image_getting;'）; 
 $ fullPath = $ _POST ['download_image']; 
 echo file_get_contents（$ fullPath）; 
  

iphone侧

 code> NSLog（@header％@，[[request responseHeaders] objectForKey：@X-Return]）; 
  

解决方案

为什么不把image_getting响应中的HTTP头？这将使解析更容易 - 您可以检索标题：

  NSString * whatever = [[request responseHeaders] objectForKey： @ X-不管]; 
  

然后[request responseData]将只包含图像。

I got stuck something annoying.

I uploaded images to server it's ok.However, when i try to download image from server i want to get image with string variable. here is my php code server side

         ....

        echo "image_getting;";
        $fullPath = $_POST['download_image'];
        echo file_get_contents($fullPath);

         ....

if i remove first line from my server [request responseData] working correctly.However, i want to also get "image_getting;" because i am also downloading some different types.

if i can clear, iphone sidewhen i say

- (void)requestFinished:(ASIHTTPRequest *)request
{
    NSString *responseString = [request responseString];
    NSLog(@"%@",responseString);

    NSArray *resultResponseArray = [responseString componentsSeparatedByString:@";"];
    if([[resultResponseArray objectAtIndex:0] isEqualToString:@"image_getting"])
    {
          NSData *responseData = [request responseData];
          UIImage * image = [UIImage imageWithData:aData];
          .......
    }
    else if...
....
}

as you can see above response data also taking echo "image_getting" how do i split it.I tried to convert and split them it didn't work.

I should say, i am very bad with php.

I will be appreciated, if someone help me.Thanks

EDIT:Solution Php side

    header('X-Return: image_getting;');
    $fullPath = $_POST['download_image'];
    echo file_get_contents($fullPath);

iphone side

    NSLog(@"header %@",[[request responseHeaders] objectForKey:@"X-Return"]);

解决方案

Why don't you put the "image_getting" into a HTTP header in the response instead? That would make the parsing much easier - you can then retrieve the header:

NSString *whatever = [[request responseHeaders] objectForKey:@"X-Whatever"];

and then [request responseData] will only contain the image.
