Question

当我试图在没有（www-authorization）的情况下使用NSURLSession和dataTaskWithRequest（我正在使用自定义委托）发布帖子请求。

效果很好。（我发送请求，在服务器上我只打印echo $ _POST ['name']，我得到“名称”作为回复。）

当我尝试使用（www-authorization）发布帖子请求时，它看起来效果正常

如果我输入正确的用户名和密码，我会得到带有状态码200和json数据的标题，如果我犯了错误，我会得到状态码为401的标题。在服务器端我做了

if (!isset($_SERVER['PHP_AUTH_USER'])) {
header('WWW-Authenticate: Basic realm="Realm"');
header('HTTP/1.0 401 Unauthorized');        
exit;
}
else
{
    $user = new btuser($_SERVER["PHP_AUTH_USER"],$_SERVER['PHP_AUTH_PW']);
    if ($user->logToDB())
    {
       header('content-type:application/json');
       header('test-login: '.$user->getname());         
       $array = array("fff"=>"tttt",
      "ddd"=>"qqqq",
      "uuuu"=>$_post['name']        
      );
      echo json_encode($array);    
    }
    else
    {
    header('HTTP/1.0 401 Unauthorized');
    unset($_SERVER['PHP_AUTH_USER']);        
    }                   
}

，但“post”请求在某处遗失）））...我得到这样的东西 - {“fff”：“tttt”，“ddd”：“qqqq”，“uuuu”：null}。

所有delegete的方法看起来都很好...... 第一种方法是

1

-(void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didSendBodyData:        (int64_t)bytesSent totalBytesSent:(int64_t)totalBytesSent totalBytesExpectedToSend:        (int64_t)totalBytesExpectedToSend{  
 NSLog(@"did send body data");
}

2

 -(void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task      didReceiveChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition, NSURLCredential *))completionHandler{
NSLog(@"challenge");
    NSURLCredential* newCredintioal;
    newCredintioal = [NSURLCredential credentialWithUser:@"testuser" password:@"testpassword" persistence:NSURLCredentialPersistenceForSession];
      [[challenge sender] useCredential:newCredintioal forAuthenticationChallenge:challenge];
    completionHandler(NSURLSessionAuthChallengeUseCredential,newCredintioal);
}

3然后再次发送了BodyBodyData。

4

 -(void)URLSession:(NSURLSession *)session dataTask:(NSURLSessionDataTask *)dataTask      didReceiveResponse:(NSURLResponse *)response completionHandler:(void (^)(NSURLSessionResponseDisposition))completionHandler
 {
 NSLog(@"did receive response %@", response);
 completionHandler(NSURLSessionResponseAllow);

 NSURLRequest* req = dataTask.currentRequest;
 NSData* dt = [req HTTPBody];
 NSString* body = [[NSString alloc] initWithData:dt encoding:NSUTF8StringEncoding];
 completionHandler(NSURLSessionResponseAllow);
 NSLog(@"credintials   %d     \n %@ \n %@ \n %@  ",dataTask.state, body, dataTask, req);
}

5

 -(void)URLSession:(NSURLSession *)session dataTask:(NSURLSessionDataTask *)dataTask      didReceiveData:(NSData *)data
 {
 NSError *jsonParsingError = nil;

 NSDictionary *urlResponseDataDict = [NSJSONSerialization JSONObjectWithData:data      options:0 error:&jsonParsingError];
 [_savedData appendData:data];

  //  NSString* str = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

NSLog(@"did receive data %@",urlResponseDataDict);
}

6

 -(void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task      didCompleteWithError:(NSError *)error
 {

 // NSError *jsonParsingError = nil;

 //  NSDictionary *urlResponseDataDict = [NSJSONSerialization JSONObjectWithData:_savedData      options:0 error:&jsonParsingError];

 NSString* str = [[NSString alloc] initWithData:_savedData      encoding:NSUTF8StringEncoding];

 NSLog(@"did complete with error - %@, data - %@, _saveddata - %@", error, str,      _savedData ); //, urlResponseDataDict);
 }

如何通过授权发出简单的数据发布请求（URLSession：task：task didReceiveChallenge :)？我做错了什么？

P.S。抱歉我的英文。

Answer 1

问题可能出在PHP脚本上：$_post与$_POST不同（请注意大小写）

具有发布请求的NSURLSession授权
