iPhone上的JSON POST请求（使用HTTPS） [英] JSON POST Request on the iPhone (Using HTTPS)
问题描述
我托管了WCF服务，并且我试图在iPhone应用程序中将其用作JSON POST请求。我打算稍后使用JSON序列化程序，但这是我对请求的要求：
I have a WCF service hosted and I'm trying to use it within an iPhone app as a JSON POST request. I plan on using the JSON serializer later, but this is what I have for the request:
NSString *jsonRequest = @"{\"username\":\"user\",\"password\":\"letmein\"}";
NSLog(@"Request: %@", jsonRequest);
NSURL *url = [NSURL URLWithString:@"https://mydomain.com/Method/"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody: requestData];
[NSURLConnection connectionWithRequest:[request autorelease] delegate:self];
在收到的数据中，我只是将其打印到控制台：
In my data received I'm just printing it to the console:
- (void) connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
NSMutableData *d = [[NSMutableData data] retain];
[d appendData:data];
NSString *a = [[NSString alloc] initWithData:d encoding:NSASCIIStringEncoding];
NSLog(@"Data: %@", a);
}
在此回复中，我收到此消息：
And within this response I get this message:
Data: <?xml version="1.0" encoding="utf-8"?>

有谁知道为什么会发生这种情况以及我哪里出错？
Does anyone know why this happens and where I'm going wrong?
我读过有关使用 ASIHTTPPost 的内容，但我无法获得在iOS4中运行的演示:(
I've read about using ASIHTTPPost instead but I can't get the demo to run in iOS4 :(
谢谢
编辑：
我刚刚用 CharlesProxy 来嗅出我从iPhone打电话时发生的事情（模拟器），这就是它给我的：
I've just used to CharlesProxy to sniff out what's happening when I call from the iPhone (Simulator) and this is what it gave me:
我注意到的唯一奇怪的是它说未为此主机启用SSL代理：在代理设置，SSL位置启用。有谁知道这意味着什么？（这也发生在我工作的Windows客户端）。
The only thing strange I've noticed is it says "SSL Proxying not enabled for this host: enable in Proxy Settings, SSL locations". Does anyone know what this means? (This also happens in my working windows client).
我刚刚在我的Windows客户端上运行它，唯一不同的是请求和响应文本这是加密编辑。我是否遗漏了某些内容以便使用安全的HTTP连接来执行此操作？
I've just ran this on my windows client and the only thing that is different is the Request and Response text which is encrypted. Am I missing something in order to use a secure HTTP connection to do this?
新编辑：
这适用于非HTTPS请求，例如： ：
http://maps.googleapis。 COM /地图/ API /地理编码/ JSON地址= UK&安培;传感器=真。所以我想问题是让iPhone通过SSL正确发送POST？
NEW This works with a non-HTTPS request such as: http://maps.googleapis.com/maps/api/geocode/json?address=UK&sensor=true. So I guess the problem is getting the iPhone to send the POST properly over SSL?
我也在使用这些方法：
- (void) connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
{
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]
forAuthenticationChallenge:challenge];
}
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
- (void) connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
if([[protectionSpace authenticationMethod] isEqualToString:NSURLAuthenticationMethodServerTrust])
{
return YES;
}
}
这让我可以做到这一点。如果我不使用它们，我会收到一个错误信息：
This allows me to get this far. If I don't use them I get an error sent back saying:
此服务器的证书无效。您可能连接到假冒mydomain.com的服务器，这可能会使您的机密信息处于危险之中。
The certificate for this server is invalid. You might be connecting to a server that is pretending to be "mydomain.com" which could put your confidential information at risk.
推荐答案
固定！
更改：
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
to：
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
您还需要以下两种方法：
You also need these two methods:
- (void) connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
{
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]
forAuthenticationChallenge:challenge];
}
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
- (void) connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
if([[protectionSpace authenticationMethod] isEqualToString:NSURLAuthenticationMethodServerTrust])
{
return YES;
}
}
