发送HTTP GET请求xcode [英] Sending an HTTP GET request xcode

问题描述

我试图将联系表单的内容发送到我的web服务。
我的代码基于一个名为StackOverFlow的主题：在Xcode中发送get方法。

我认为我遵循规则，但它仍然不起作用。我不想让你失去时间，但我开始生气。

   - （IBAction）send： （id）sender {
 
 
 NSString * get = [[NSString alloc] initWithFormat：@& Contact %% 5BFirstName %% 5D =％@ + First& Contact %% 5BLastName％ ％5D =％@ +最后&安培;联系%% 5BMail %% 5D =％@&安培;联系%% 5BPhone %% 5D =％@&安培;联系%% 5BMotivations %% 5D =％@&安培;联系%% 5BCommentaires %% 5D =％@，prenomtxtfield.text，nomtxtfield.text，emailtxtfield.text，teltxtfield.text，pvController.mail.motiv，questiontxtview.text]; 
 
 
 NSData * getData = [get dataUsingEncoding：NSASCIIStringEncoding allowLossyConversion：YES]; 
 
 NSString * getLength = [NSString stringWithFormat：@％d，[getData length]]; 
 
 NSMutableURLRequest * request = [[NSMutableURLRequest alloc] init]; 
 [request setURL：[NSURL URLWithString：@http://xxx.zfort.net/index.php?r=site/contactAdd]]; 
 [request setHTTPMethod：@GET]; 
 [request setValue：getLength forHTTPHeaderField：@Content-Length]; 
 [request setValue：@application / x-www-form-urlencodedforHTTPHeaderField：@Content-Type]; 
 [request setHTTPBody：getData]; 
  

我的字段是：姓氏，名字，邮件，电话，Motiv，问题。
我的web服务地址是： http://xxx.zfort.net/index.php？

谢谢大家（即使你没有回应...你以前的评论都已经帮助过我）

PS：它可能是一个编码值问题？ 试试这个：

p>

  NSString * sendingtring = [NSString StringWithFormat：@http://xxx.zfort.net/index.php?r=site/ contactAdd和放大器;联系%% 5BFirstName %% 5D =％@ +首先和放大器;联系%% 5BLastName %% 5D =％@ +尾和放大器;联系%% 5BMail %% 5D =％@&放大器;联系%% 5BPhone %% 5D =％@ &安培;联系%% 5BMotivations %% 5D =％@&安培;联系%% 5BCommentaires %% 5D =％@，prenomtxtfield.text，nomtxtfield.text，emailtxtfield.text，teltxtfield.text，pvController.mail.motiv，questiontxtview。文本]; 
 
 [NSURLConnection initWithRequest：[NSURLRequest requestWithURL：[NSURL URLWithString：sendingtring]] delegate：self]; 
  

然后您不必执行

<$ p $ （NSURLConnection *）连接didReceiveResponse：（NSURLResponse *）响应

$ b （NSURLConnection *）连接didReceiveData：（NSData *）数据
$ p

$ $ p $ $ b

I'm trying to send the content of a contact form to my webservice. My code is based on a StackOverFlow topic named : Sending get method in Xcode .

I think i follow the rules but it still doesn't work. I don't want u to lose your time, but i'm starting to get mad.

- (IBAction)send:(id)sender{


NSString *get = [[NSString alloc] initWithFormat:@"&Contact%%5BFirstName%%5D=%@+First&Contact%%5BLastName%%5D=%@+Last&Contact%%5BMail%%5D=%@&Contact%%5BPhone%%5D=%@&Contact%%5BMotivations%%5D=%@&Contact%%5BCommentaires%%5D=%@",prenomtxtfield.text,nomtxtfield.text,emailtxtfield.text,teltxtfield.text,pvController.mail.motiv,questiontxtview.text];


NSData *getData = [get dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSString *getLength = [NSString stringWithFormat:@"%d", [getData length] ];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:@"http://xxx.zfort.net/index.php?r=site/contactAdd"]];
[request setHTTPMethod:@"GET"];
[request setValue:getLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:getData];

My fields are : Last Name , First Name , Mail, Phone , Motiv, Question . My webservice addr is : http://xxx.zfort.net/index.php?

Thank you all (even you're not responding... you've all already helped me in the past with your comments)

PS: it may be an issue of encoding values ?

解决方案

Try this:

NSString * sendstring=[NSString StringWithFormat:@"http://xxx.zfort.net/index.php?r=site/contactAdd&Contact%%5BFirstName%%5D=%@+First&Contact%%5BLastName%%5D=%@+Last&Contact%%5BMail%%5D=%@&Contact%%5BPhone%%5D=%@&Contact%%5BMotivations%%5D=%@&Contact%%5BCommentaires%%5D=%@",prenomtxtfield.text,nomtxtfield.text,emailtxtfield.text,teltxtfield.text,pvController.mail.motiv,questiontxtview.text];

[NSURLConnection initWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:sendstring]] delegate:self];

Then you haven to implement

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response

and

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
