iPhone上的JSON POST请求(使用HTTPS)
ing*_*.am 11 iphone ssl https json objective-c
我托管了一个WCF服务,我试图在iPhone应用程序中使用它作为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:
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:
- (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);
}
在这个回复中,我得到了这样的信息:
Data: <?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</div>

有谁知道为什么会这样,我哪里出错了？
我已经阅读过有关使用ASIHTTPPost但我无法让这个演示在iOS4中运行:(
谢谢
编辑:
我刚刚习惯CharlesProxy来嗅出我从iPhone(模拟器)打电话时发生的事情,这就是它给了我的东西:
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).
我刚刚在我的Windows客户端上运行它,唯一不同的是加密的请求和响应文本.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？
新编辑:这适用于非HTTPS请求,例如:http: //maps.googleapis.com/maps/api/geocode/json？address = UK&_sensor = true.所以我想问题是让iPhone通过SSL正确发送POST？
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,说:
此服务器的证书无效.您可能连接到假装为"mydomain.com"的服务器,这可能会使您的机密信息面临风险.

固定!
更改:
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
至:
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
您还需要以下两种方法:
- (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;
}
}
