我正在尝试使用下面的代码通过ftp发送一个字符串,但是我收到一个错误:
{
//miscellaneous lines of code.....
//Convert contents of shopping cart into a property list
[Cart serializeCart];
//now need to transport the propertyList to the webserver
//first step is get the serialized propertylist from the documents folder
NSString *pathToSerializedCart = [rootPath stringByAppendingPathComponent:@"serializedCart.plist"];
NSString *shoppingCartString;
if (![fileManager fileExistsAtPath:pathToSerializedCart])
{
NSLog(@"ERROR:\nCouldnt find serialized cart in documents folder.");
}
else
{
NSData *serializedData = [NSData dataWithContentsOfFile:pathToSerializedCart];
shoppingCartString = [[NSString alloc] initWithData:serializedData encoding:NSUTF8StringEncoding];
}
NSLog(@"%@", shoppingCartString);
//Now that the cart is converted into a string. it is ready for transport
NSURL *url = [NSURL URLWithString:@"ftp://username:password@domainName.com/folder/serializedCart.xml"];
BOOL OK =[shoppingCartString writeToURL:url atomically:NO encoding:NSUTF8StringEncoding error:&error];
if(!OK) {
NSLog(@"Error writing to file %@ , error = %@", url, [error localizedFailureReason]);
}
我正在为此代码获取以下控制台输出:
Error writing to file ftp://username:password@domainName.com/folder/serializedCart.xml , error = (null)
其中一个变量:_domain
在最后一行的这个错误对象中,我在调试过程中将鼠标移到它上面说NSCocoaErrorDomain
我不确定如何调试它。 有人可以提出任何建议吗?
答案 0 :(得分:0)
writeToURL:..
方法不支持FTP
协议。您必须使用其他机制将字符串内容写入ftp服务器。您可以查看ios-ftp-server
等工具来处理此类上传。您还可以从Apple查看此sample code
。
