如果想同时post字符串以及文件到服务器，则在网页中一定要设置 enctype="multipart/form-data".
html测试页面:
<html>
<body>
<form action="" method="post"enctype="multipart/form-data">
<input type=text name="name" />
<input type=file name="file1" />
<input type="submit" />
</form>
</body>
</html>
|
此时，使用Firefox的Tamper Data附加组件，是看不到上传文件的过程的，只能看到post信息里面的文件名称。
而，在ASI中，这个multipart部分应该是自己给添加上的。
iPhone代码:
NSString *fileName = [[NSBundle mainBundle] pathForResource: @"01"ofType: @"mov"];
NSString *url = @"";
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL: [NSURL URLWithString: url]];
[request setPostValue: @"MyName" forKey: @"name"];
[request setFile: fileName forKey: @"this_is_file"];
[request buildRequestHeaders];
NSLog(@"header: %@", request.requestHeaders);
[request startSynchronous];
NSLog(@"responseString = %@", request.responseString);
|
服务器php代码:
<?php
var_dump($_FILES);
$header = print_r(apache_request_headers(), true);
echo $header;
|
服务器返回Log:
2011-08-07 18:33:36.991 TestRecordVideo[2836:15503] responseString = array(1) {
["this_is_file"]=>

["tmp_name"]=>
string(14) "/tmp/phpmoUHlk"
["error"]=>

["size"]=>

}
}
