发送http删除请求
我需要如何发送 http 删除请求，我已经实现了下面的代码，
- (void) deleteSyncRequestWithURL:(NSString *) url
{
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"DELETE"];
_connection = [[NSURLConnection connectionWithRequest:request delegate:self] retain];
}
但我得到了 404 状态。
有谁知道我错过了什么？
PS：我使用的是xcode 3.2.3，模拟器4.0
I need to how I can send an http delete request, I've implemented the code below
- (void) deleteSyncRequestWithURL:(NSString *) url
{
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:@"DELETE"];
_connection = [[NSURLConnection connectionWithRequest:request delegate:self] retain];
}
But I've got a 404 status.
Does anyone know what I'm missing??
P.S: I'm using xcode 3.2.3, simulator 4.0

看起来您的删除请求似乎已正确发出，但服务器选择以 404 - 文档未找到错误进行响应。
您也可以控制服务器应用程序吗？您确定服务器在该 URL 上有响应删除请求的资源吗？
如果您对发出的删除请求感到怀疑 - 我将使用 HTTP 代理直接检查请求，然后您可以与其他客户端进行比较。我会使用 Wireshark （在 Mac 上）。如果另一个客户端在 PC 上，您可以使用 Fiddler，这非常好。
It looks as if your Delete request is being issued correctly, but the server is choosing to respond with a 404 - document not found error.
Do you have control over the server application too? Are you sure the server has a resource at that URL that responds to a Delete request?
If you are suspicious of the Delete request being made - I would use an HTTP proxy to examine the request directly, you can then compare to your other client. I would use Wireshark (on the Mac). If the other client is on a PC, you could use Fiddler, which is excellent.
