iOS9苹果将原http协议改成了https协议的方法

2019年07月24日  | 移动技术网移动技术  | 我要评论

解决方法：

在info.plist 加入key

<key>nsapptransportsecurity</key>
<dict>
<key>nsallowsarbitraryloads</key>
<true/>
</dict>

下面给大家介绍ios中http 和https 协议的访问

最近做个项目，开始采用的是http协议实现客户端和服务器端的交互，后来需要改成https协议。在修改的过程中发现了一些问题，解决方案如下：

http：

nsstring *urlstring =[nsstring stringwithformat:@"https://127.0.0.1/default.aspx?user=%@",@"111"];
nsmutableurlrequest *request = [[[nsmutableurlrequest alloc] init] autorelease];
[request seturl:[nsurl urlwithstring:urlstring]];
[request sethttpmethod:@"get"];
nshttpurlresponse* urlresponse = nil;
nserror *error = [[nserror alloc] init];
nsdata *responsedata = [nsurlconnection sendsynchronousrequest:request returningresponse:&urlresponse error:&error];
nsmutablestring *result = [[nsmutablestring alloc] initwithdata:responsedata encoding:nsutf8stringencoding];
nslog(@"the result string is :%@",result);

https

事件触发 

{ 
nsstring *urlstring =[nsstring stringwithformat:@"https://127.0.0.1/default.aspx?user=%@",@"111"];
nsmutableurlrequest *request = [[nsmutableurlrequest alloc] initwithurl:[nsurl urlwithstring:urlstring] cachepolicy:nsurlrequestreloadignoringlocalcachedata timeoutinterval:5];
//设置请求方式为get
[request sethttpmethod:@"get"];
//添加用户会话id
[request addvalue:@"text/html" forhttpheaderfield:@"content-type"];
//连接发送请求
finished = false;
nsurlconnection *conn = [[nsurlconnection alloc] initwithrequest:request delegate:self];
//堵塞线程，等待结束
while(!finished) {
[[nsrunloop currentrunloop] runmode:nsdefaultrunloopmode beforedate:[nsdate distantfuture]];
}
} 
- (void)connection:(nsurlconnection *)connection didreceiveresponse:(nsurlresponse*)response 
{}
- (void)connectiondidfinishloading:(nsurlconnection *)connection 
{
//[_waitingdialog dismisswithclickedbuttonindex:0 animated:no];
[connection release];
}
-(void)connection:(nsurlconnection *)connection didfailwitherror:(nserror *)error
{ 
}
- (bool)connectionshouldusecredentialstorage:(nsurlconnection *)connection{
return no;
}
//下面两段是重点，要服务器端单项https 验证，ios 客户端忽略证书验证。
- (bool)connection:(nsurlconnection *)connection canauthenticateagainstprotectionspace:(nsurlprotectionspace *)protectionspace {
return [protectionspace.authenticationmethod isequaltostring:nsurlauthenticationmethodservertrust];
} 
- (void)connection:(nsurlconnection *)connection didreceiveauthenticationchallenge:(nsurlauthenticationchallenge *)challenge { 
nslog(@"didreceiveauthenticationchallenge %@ %zd", [[challenge protectionspace] authenticationmethod], (ssize_t) [challenge previousfailurecount]);
if ([challenge.protectionspace.authenticationmethod isequaltostring:nsurlauthenticationmethodservertrust]){
[[challenge sender] usecredential:[nsurlcredential credentialfortrust:challenge.protectionspace.servertrust] forauthenticationchallenge:challenge];
[[challenge sender] continuewithoutcredentialforauthenticationchallenge: challenge];
}
} 
nslog(@"get the whole response");
//[receiveddata setlength:0];
}
//处理数据 
- (void)connection:(nsurlconnection *)connection didreceivedata:(nsdata *)data
{ 
}
