IOS URL中文乱码问题解决方案
IOS解决URL中文乱码问题解决
在做一个HTTPS连接时,要客户端合成一段HTTPS地址
如果地址含中文的话程序会crash,检查发现原来是中文没有转码的原因
在NSString库里面找到了下面两个方法
-(NSString*)stringByAddingPercentEscapesUsingEncoding:(NSStringEncoding)encoding -(NSString*)stringByReplacingPercentEscapesUsingEncoding:(NSStringEncoding)encoding
试了下,有效
NSString*string1=@"https://www.cloudsafe.com/文件夹"; NSString*string2=[string1stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSString*string3=[string2stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSString*string4=[string2stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSString*string5=[string3stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSString*string6=[string4stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSString*string7=[string5stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
输出string1-7结果如下
string1:https://www.cloudsafe.com/文件夹 string2:https://www.cloudsafe.com/%E6%96%87%E4%BB%B6%E5%A4%B9 string3:https://www.cloudsafe.com/%25E6%2596%2587%25E4%25BB%25B6%25E5%25A4%25B9 string4:https://www.cloudsafe.com/文件夹 string5:https://www.cloudsafe.com/%E6%96%87%E4%BB%B6%E5%A4%B9 string6:https://www.cloudsafe.com/文件夹 string7:https://www.cloudsafe.com/文件夹
简单说下我是如何使用的:
在合成URL后,给整个String转码两次
NSMutableString*address=[[NSMutableStringstringWithString:SetNiChengStringWithoutUserNameAndNiCheng]mutableCopy]; address=[[addressstringByAppendingString:app.name]mutableCopy]; address=[[addressstringByAppendingString:@"/"]mutableCopy]; address=[[addressstringByAppendingString:_nameTextField.text]mutableCopy]; address=[[addressstringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]mutableCopy]; address=[[addressstringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]mutableCopy];
服务器端如何只是简单存储,服务器接收数据后可以不用转码成中文
当客户端请求这部分数据时,由客户端自己解码就好了
获取到字串后解码一次就可以正常显示为中文了:
str=[strstringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
