iOS - NSURLConnection finished with error - code -1002

 

网络请求会异常，比如报错：Error domain: @"NSURLErrorDomain" - code: 1002

在回调的地方打一个断点，然后用命令行查看下什么错误： po error
当错误是：**[Error Domain=NSURLErrorDomain Code=-1002 ] "unsupported URL" **
*Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo={NSLocalizedDescription=unsupported URL, NSUnderlyingError=0x7fa9b1d06120 {Error Domain=kCFErrorDomainCFNetwork Code=-1002 "(null)"}}  *  的时候是url编码问题，处理一下URL编码就好了

我这边是后台返回的拼接的接口多了“/”,导致统一的域名格式不统一

处理方法:


iOS 8 要用utf8转码：

urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];


iOS 8 以后要用这个方法：

urlString = [urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet characterSetWithCharactersInString:@"#%^{}\"[]|\\<> "].invertedSet];
