Iphone 向服务器发送Post请求

我有这个php代码

<?php  
       $users = $this->Session->read("user");
       $varFName = $users['User']['first_name'];
       $varLName = $users['User']['last_name'];
       $message = "Hello,
 I would like to invite you to Clicksays! ".$varFName." ".$varLName;
       echo $this->Form->create('User', array('id' => 'sendEmailRequest', 'style'=>'padding : 0px;', 'url' => array('controller' => 'Contacts', 'action' => 'addEmailRequest')));
       echo $this->Form->input('Email', array('id' => 'email', "size"=>"40"));
       echo $this->Form->textarea("Message", array("type"=>"textarea", "id"=>"PreviewEmail", "style"=>"display:none;","rows"=>"5", "cols"=>"45", "value"=>$message));
       echo $this->Form->button('Preview and edit invitation Clickup', array("id" => "butInvite", "type"=>"button"));
       echo $this->Form->button('Send invitation Clickup', array('id' => 'butSendInvitation',  'type'=>'submit'));
       echo $this->Form->end(); ?>

现在我非常确定我需要将数组作为HTTP主体，但我不知道如何放置。我不是一个网络人，对网络编程和方法知之甚少

我怎样才能传递细节？如果没有它，它将无法工作，并发布错误以输入用户的详细信息，该代码也存在于php中。

RestKit非常适合在iOS应用程序中处理JSON内容。查看此教程：

尝试此教程

    NSString *urlString = @"Your url";

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];

    NSMutableData *body = [NSMutableData data];


    NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
    [request addValue:contentType forHTTPHeaderField:@"Content-Type"];




    [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[NSData dataWithData:imageData]];
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];



    // Text parameter1
    // NSString *param1 = @"parameter text";
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"name\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:param1] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];



    // Another text parameter
    // NSString *param2 = @"Parameter 2 text";
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"desc\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:param2] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];


    // close form
    [body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    // set request body
    [request setHTTPBody:body];

与上面的代码类似，您可以使用HTTP post方法发送多个值。

如果您希望以数组形式发送，则应以Json字符串形式发送。您可以使用NSJSONSerialization类将数组转换为Json字符串尝试发布答案..如果有帮助..我也会接受+1给您..顺便说一下..我需要ios4.0兼容性。。

    NSString *urlString = @"Your url";

    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];

    NSMutableData *body = [NSMutableData data];


    NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
    [request addValue:contentType forHTTPHeaderField:@"Content-Type"];




    [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[NSData dataWithData:imageData]];
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];



    // Text parameter1
    // NSString *param1 = @"parameter text";
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"name\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:param1] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];



    // Another text parameter
    // NSString *param2 = @"Parameter 2 text";
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"desc\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:param2] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];


    // close form
    [body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    // set request body
    [request setHTTPBody:body];
