iphone将数据发布到网址

Question

这是我需要发布http://www.mysite.com/save?details= {“name”}

的字符串

我尝试以下代码;

NSString * post = [NSString stringWithFormat：@“details = {\”name \“}”];

NSString *hostStr = @"http://www.mysite.com/save?";
hostStr = [hostStr stringByAppendingString:post];
NSData *dataURL =  [NSData dataWithContentsOfURL: [ NSURL URLWithString: hostStr]];    
NSString *serverOutput = [[NSString alloc] initWithData:dataURL encoding: NSASCIIStringEncoding];

但serverOutput总是= null，除非我只是{name}。但我需要那里的qutoes :(

Answer 1

您应该将所有内容转换为有效的HTTP符号。

e.g：

hostStr = [hostStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

...我的猜测是您的网络服务器拒绝无效网址。

Answer 2

错误..

NSString * post = [NSString stringWithFormat：@“details = {\”name \“}”];

<强>正确：

NSString * post = [NSString stringWithString：@“details = {\”name \“}”];
