iphone SDK:将图像从iphone上传到php服务器发送空文件?(内部示例代码链接)
我尝试通过 PHP 将照片和 GPS 位置发送到服务器,
这是 PHP 部分:从这里复制 保存上传的文件
上面的示例在服务器上的 PHP 临时文件夹中创建上传文件的临时副本。
当脚本结束时,临时复制的文件就会消失。要存储上传的文件,我们需要将其复制到不同的位置:
<?php
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
?>
上面的脚本检查文件是否已存在,如果不存在,则将文件复制到指定的文件夹。
注意:这个例子将文件保存到一个名为“upload”的新文件夹
,现在回到iOS部分,我只能将GPS位置发送到服务器,这很简单,因为只是一个字符串。
你可以在这里下载示例代码
但是图像不是,我做了一些搜索,发现了这个讨论
我直接将代码放在我的发送 GPS&image 中按钮
最好的是它可以反馈我发送文件成功或失败
这是我将照片发送到服务器后收到的最多消息
1.文件无效
2.返回代码:
上传:
类型:
大小:0 Kb
临时文件:
存储在:upload/
我按照一些指南将图像保存到 NSData
NSData *photoData= UIImageJPEGRepresentation(self.theimageView.image, 1.0);
,我还检查里面是否有数据或不是
简单地将这段代码添加到按钮操作中
if (photoData == nil) {
NSLog(@"The photo is nothing !!!");
}
else {
NSLog(@"Photo inside !!!!");
它工作得很好......
但是如何将图像上传到服务器???
也许我需要提供一个文件名然后上传它???
但是如何...
我以前从未使用过相机功能并上传数据
希望有人能解决这个问题
非常感谢!!!
I try to send a photo and GPS location to server via PHP
here is the PHP part:Copy from here
Saving the Uploaded File
The examples above create a temporary copy of the uploaded files in the PHP temp folder on the server.
The temporary copied files disappears when the script ends. To store the uploaded file we need to copy it to a different location:
<?php
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
}
}
else
{
echo "Invalid file";
}
?>
The script above checks if the file already exists, if it does not, it copies the file to the specified folder.
Note: This example saves the file to a new folder called "upload"
now back to iOS part ,I only can send GPS location to server ,it's easy because just a string.
and you can download sample code here
But an image is not,I do some search and found this discussion
I directly put the code in my send GPS&image button
the best thing is it can feedback I send the file success or failed
this is the most message I got after I send photo to server
1.Invalid file
2.Return Code:
Upload:
Type:
Size: 0 Kb
Temp file:
Stored in: upload/
I follow some guide to save image to NSData
NSData *photoData= UIImageJPEGRepresentation(self.theimageView.image, 1.0);
and I also check there is data inside or not
so simply add this code into Button action
if (photoData == nil) {
NSLog(@"The photo is nothing !!!");
}
else {
NSLog(@"Photo inside !!!!");
It works fine.......
But How To Upload An Image To Server ???
maybe I need to give a file name then upload it ???
but how to...
I never use camera function and upload data before
Hope someone can figure out this problem
Many Great Thanks !!!

使用 HTTP 多部分 POST 或 ASIHTTPRequest
use HTTP multipart POST or ASIHTTPRequest
添加这个很好
但是当我尝试放入按钮操作时
它收到了很多错误消息,我认为委托问题
首先编译器说“请求未声明”和“ASIFormDataRequest未声明”
和“requestString未声明”
我尝试给出请求和requestString声明
所以我使用
ASIFormDataRequest *request;
和NSString *requestString;
它清除了有关“equestString undeclared”的错误
我不知道如何声明 ASIFormDataRequest 所以它仍然是一个错误...
我把它放在 IBAction 中对吗???
我在这里查看一些示例
再次感谢~你真是个好人!
更多编辑:
好的,这是有关如何导入必要的 .h .m 和框架的更多步骤
在此处下载
并导入此标头:
iPhone 项目还必须包括:
导入框架:
CFNetwork
SystemConfiguration.framework
MobileCoreServices.framework
CoreGraphics.framework
libz.1.2.3。 dylib
It's fine to add this
But When I try to put in my button action
It got many error message ,I think is delegate problem
first complier says "request undeclared" and "ASIFormDataRequest undeclared"
and "requestString undeclared"
I try to give request and requestString declared
So I use
ASIFormDataRequest *request;
andNSString *requestString;
It clear an error about "equestString undeclared"
I don't know how to declared ASIFormDataRequest so it still a error...
Did I right to put this in IBAction ???
I look some example here
Thanks again~you are a really nice guy !
More Edit :
OK, Here is more step about how to import necessary .h .m and framework
download here
and import this header :
iPhone projects must also include:
than import Framework:
CFNetwork
SystemConfiguration.framework
MobileCoreServices.framework
CoreGraphics.framework
libz.1.2.3.dylib
好的,这是 iPhone3 和 iPhone3 之间的一个小错误。 iPhone4/touch4
@ dhil 的答案几乎是正确的,你只需要给出一个正确的密钥(取决于服务器)
好吧...现在如果你使用 iPhone3 ,并且你不给出
requestString
alloc它运行良好〜
但如果你在 iPhone4/touch4 上运行,
即使两个设备都是 iOS 4.1,
它也会导致 EXC_BAD_ACCESS所以...希望这个答案能帮助你节省上传时间图像到服务器。
OK,Here is a small bug between iPhone3 & iPhone4/touch4
@ dhil's Answer is almost right , You just need to give a right key (depends on Server)
Ok...now if you use iPhone3 , and you don't give
requestString
allocIt runs fine ~
But if you run on iPhone4/touch4 ,It will cause EXC_BAD_ACCESS
even both device is iOS 4.1
So...Hope this answer will help you to save time about upload image to server.
