從NSURLSessionDataTask請求的NSData響應獲取XML

Question

我發送一個NSURLSessionDataTask，並且我得到NSData作爲響應。它應該包含XML。但我無法得到它。

當我發送命令行上一個curl請求時，它按預期工作

NSURLSessionDataTask* dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { //5 
    if (!error) { 
     NSLog(@"%@", [response description]); 
     NSLog(@"%@", data); // some data I can not understand. 
    } 
}]; 

請求：

{ 
    "Content-Type" = "application/xml; charset=\"utf-8\""; 
} 

響應

{ status code: 207, headers { 
    "Accept-Ranges" = bytes; 
    Connection = close; 
    "Content-Length" = 1282; 
    "Content-Type" = "text/xml"; 

請提供指針

Answer 1

text/xml僅僅是XML字符串，因此通過

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

響應數據轉換爲字符串您的代碼將是：

NSURLSessionDataTask* dataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) { //5 
    if (!error) { 
     NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
     NSLog(@"%@", responseString); 
    } 
}];
