iOS通过身份验证从服务器读取xml数据,ios,xml,xml-parsing,Ios,Xml,Xml Parsing,在我的应用程序中，我必须从服务器读取xml数据。要访问此服务器，必须提供用户名和密码，我如何解决这个问题？我尝试使用以下代码读取xml数据： -(id)sendRequestToURL:(NSString*)url withMethod:(NSString*)method { NSURL *finalUrl; if ([method isEqualToString:@"GET"]) { finalUrl = [NSURL URLWithString:url];

在我的应用程序中，我必须从服务器读取xml数据。要访问此服务器，必须提供用户名和密码，我如何解决这个问题？我尝试使用以下代码读取xml数据：

-(id)sendRequestToURL:(NSString*)url withMethod:(NSString*)method {
    NSURL *finalUrl;
    if ([method isEqualToString:@"GET"]) {
        finalUrl = [NSURL URLWithString:url];
    } else {
        NSLog(@"Metodo non implementato");
    }
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:finalUrl];
    [request setHTTPMethod:method];
    [request setValue:@"x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-type"];

    NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
    if (connection) {
        [connection start];
    }
    return connection;
}

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    NSLog(@"Ho ricevuto una risposta");
}

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    NSLog(@"Ho ricevuto dei dati: %@", data);
    NSMutableData *test = [[NSMutableData alloc]init];
    [test appendData:data];
    NSString *string = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
    NSLog(@"%@", string);
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSLog(@"Ho terminato di caricare");
}

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    NSLog(@"%@", error);
}

它连接正确，但如果我试图阅读问题所在，我会得到以下HTML：

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>401 Authorization Required</title>
</head><body>
<h1>Authorization Required</h1>
<p>This server could not verify that you
are authorized to access the document
requested.  Either you supplied the wrong
credentials (e.g., bad password), or your
browser doesn't understand how to supply
the credentials required.</p>

因此，我想有必要提供用户名和密码，但我如何才能做到这一点？

base64EncodedString设置身份验证标头字段：

NSString *authStr = [NSString stringWithFormat:@"%@:%@", @"myusername", @"mypassword"];
NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding];
NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodedString]];
[request setValue:authValue forHTTPHeaderField:@"Authorization"];

要将NSData转换为base64字符串，您需要

我通过以下方式解决了此问题：

    NSString *address = [NSString stringWithFormat:@"http://54.204.6.246/magento8/api/rest/products/?category_id=3"];
    [self sendRequestToURL:address withMethod:@"GET"];

    -(id)sendRequestToURL:(NSString*)url withMethod:(NSString*)method {
    NSURL *finalUrl;
    if ([method isEqualToString:@"GET"]) {
        finalUrl = [NSURL URLWithString:url];
    } else {
        NSLog(@"Metodo non previsto");
    }
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:finalUrl];
    [request setHTTPMethod:method];
    NSString *authStr = [NSString stringWithFormat:@"%@:%@", @"user", @"password"];
    NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding];
    NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodedString]];
    [request setValue:authValue forHTTPHeaderField:@"Authorization"];
    [request setValue:@"x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-type"];

    NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
    if (connection) {
        [connection start];
    }
    return connection;
}

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    NSLog(@"Ho ricevuto una risposta");
}

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    NSLog(@"Ho ricevuto dei dati: %@", data);
    jsonCategory = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSLog(@"Ho terminato di caricare");
    JsonCategoryReader *reader = [[JsonCategoryReader alloc]init];
    [reader parseJson:jsonCategory];

}

我希望它对其他有同样问题的人有用。注意代码，它只是一个片段，可能没有所有的{}

好的，我如何集成NSData+Base64.h？下载您在此处发布的链接中的代码并直接插入我的代码就足够了吗？是的，只需将头文件和实现放在项目中，然后将导入添加到NSData+Base64.h。
