好的。我一直在处理原始 HTTP 请求，发现我可以将原始 HTTP 响应发布到 NSLog 中，而且我几乎将原始 HTTP 请求破解到 NSLog 中。我现在有点卡住了。

代码示例

   NSString *CurrentWebURL = webView.request.URL.absoluteString;
   NSURLSession *session= [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
   [[session dataTaskWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:CurrentWebURL]] completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
   NSDictionary *requestdictionary = [request allHTTPHeaderFields];
   NSLog(@"----shouldStartLoadWithRequest Raw HTTPRequest Start ----");
   for (NSString *Object in [requestdictionary allKeys]) {
         NSLog(@"%@: %@",Object, [requestdictionary objectForKey:Object]);
   }
   NSLog(@"----shouldStartLoadWithRequest Raw HTTPRequest Finish ----"] withlevel:SPECIAL_LOG);

   }]resume];

原始请求:

Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
User-Agent: Mozilla/5.0 (iPad; CPU OS 7_0_6 like Mac OS X)  AppleWebKit/537.51.1 (KHTML, like Gecko) Mobile/11B651

它应该显示“Get:URL”、“HOST”、“Connection: Keep-alive”、“Accept-Encoding”、“Accept”、“Cookie”、“Connection”、“Accept-Language”和“用户代理”。

我的问题是为什么它只显示“接受”和“用户代理”？

发出请求:

  NSURL *url = [NSURL URLWithString:PortalURL];

  NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
  [request setHTTPShouldHandleCookies:YES];
  [request setHTTPMethod: @"GET"];

Fiddler 请求跟踪(没有任何自定义 header ):

  GET http://URL/ HTTP/1.1
  Host: Host.co.uk
  Connection: keep-alive
  Accept-Encoding: gzip, deflate
  Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
  Cookie: IsosecCookie=Chris%20Beckett
  Connection: keep-alive
  Accept-Language: en-gb
  User-Agent: Mozilla/5.0 (iPad; CPU OS 7_0_6 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Mobile/11B651

在 NSLog 中记录请求 header :

  Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
  User-Agent: Mozilla/5.0 (iPad; CPU OS 7_0_6 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Mobile/11B651

最佳答案

我得出的结论是，在 iOS 中使用 NSURLRequest 获取原始 HTTP 请求是不可能的，您只能获取“Accept”和“User-Agent”。

不过，我已经解决了问题，为了获取原始 HTTP 请求，我使用 php 来获取 header 。我知道这不是最好的解决方案，但它确实有效，而且无需继续通过 Fiddler 或 Charles 代理之类的代理即可记录此信息真是太棒了。

iOS 代码

NSURL *PHPURL = ([NSURL URLWithString:[NSString stringWithFormat:@"http://office.isosec.co.uk/Audit/testRequest.php?"]]);
request = [[NSMutableURLRequest alloc] initWithURL:PHPURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10.0];
[request setHTTPMethod: @"GET"];
[request setHTTPShouldHandleCookies:YES];

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:NO];

PHPResponse = [NSMutableData data];

if( connection == nil ) {
    [ViewController remoteLog:[NSString stringWithFormat:@"PHPRequest Connection Failed"] withlevel:SPECIAL_LOG];
} else {
    [ViewController remoteLog:[NSString stringWithFormat:@"PHPRequest Connection Started"] withlevel:SPECIAL_LOG];
    [connection scheduleInRunLoop:[NSRunLoop mainRunLoop]
forMode:NSDefaultRunLoopMode];
    [connection start];
}

PHP代码

foreach (getallheaders() as $name => $value) {
    echo "$name: $value,";
}
