iOS NSURLConnection JSON失敗

我有點不安，我通常使用MKNetworkKit或某個庫，但是這次我不得不手動執行HTTP請求，因爲我想設置正文數據。iOS NSURLConnection JSON失敗

這是我的要求：

NSData* data = [NSJSONSerialization dataWithJSONObject:questionDict 
               options:NSJSONWritingPrettyPrinted error:Nil]; 

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

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; 
[request setURL:fullAPIURL_URL]; 
[request setHTTPMethod:@"POST"]; 
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
[request setHTTPBody:[NSData dataWithContentsOfFile:aStr]]; 

NSLog(@"Data: %@",aStr); 

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self]; 
[connection start];

這是一個HTTPS的SSL如果這能幫助？

然後我處理這樣的響應;

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { 
    return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; 
} 

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { 

    [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge]; 
} 

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { 
    NSLog(@"Response: %@",response); 
} 

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { 
    [receivedData_ appendData:data]; 
} 

- (void)connectionDidFinishLoading:(NSURLConnection *)connection { 
    NSLog(@"Succeeded! Received %d bytes of data", [receivedData_ length]); 
    NSString *responeString = [[NSString alloc] initWithData:receivedData_ 
                encoding:NSUTF8StringEncoding]; 
    NSLog(@"Response: %@",responeString); 

    // Assume lowercase 
    if ([responeString isEqualToString:@"true"]) { 
     // Deal with true 
     return; 
    } 
    // Deal with an error 
}

我只是在日誌中得到這個;

{ status code: 403, headers { 
    "Cache-Control" = "no-cache, must-revalidate"; 
    Connection = close; 
    "Content-Length" = 48; 
    "Content-Type" = "application/json"; 
    Date = "Mon, 06 Jan 2014 10:22:40 GMT"; 
    Expires = "Mon, 06 Jan 2014 10:22:40 GMT"; 
    P3P = "policyref=\"/w3c/p3p.xml\", CP=\"ALL DSP COR CURa OUR IND COM NAV CNT\""; 
    Pragma = "no-cache"; 
    Server = Apache; 
    "X-Powered-By" = PleskLin; 
} } 
Succeeded! Received 0 bytes of data 
Response:

讚賞任何幫助，我已經測試了這個使用捲曲客戶端和它的作品，因爲它應該做的。我認爲這與使用SSL進行身份驗證有關？

狀態代碼是在這裏一大線索。狀態碼403是「[Forbidden]（http://httpstatus.es/403）」。如果認證是問題，你會期望一個401.向我們展示你的cURL命令可能是有用的。 – neilco

您缺少標題字段。請求開發該API的團隊中的所有關鍵值標題和正文 – amar

我已經修復了我自己的問題。對於其他人來說，它是下面一行;

[request setHTTPBody:[aStr dataUsingEncoding:NSUTF8StringEncoding]];

我錯過了「dataUsingEncoding」
