將Web服務從GET轉換爲POST

Question

我創建了一個Web服務來在iOS應用程序和Joomla網站之間進行通信，並且我使用GET方法在移動應用程序和Web服務之間進行通信， web服務和控制器（做文件並返回數據的PHP文件），但我沒有找到如何將實現轉換爲POST方法，這裏是實際系統：

ws.php：它是web服務（簡單示例）

<?php 
     $id = $_GET['id'] ; // get the data from the URL 

// here i make testes 

// then I redirect to the controller of the Joomla component that receive 
// the call of the request the URL is actually the attribute "action" of 
// an existing HTML Form that implement the login system, I added a 
// parameter called web service to help me to modify the controller 
// to make the difference between a normal call and a web service call 

header("Location: index.php?option=com_comprofiler&task=login&ws=1&id=1"); 
?> 

Controller.php這樣：Web服務調用的接收器和網絡電話（從瀏覽器）

<?php 
// code added by me, in the existent controller of the component 
// it was waiting for a form submitting, so I got to convert my data to POST here 

if (isset($_GET['ws'])) // it's a web service call 
{ 
    $_POST['id'] = $_GET['id'] ; 

    // do the task ... 

    if ($correctLogin) // just an example 
    echo "1" 
    else 
    echo '0'; 
} 
?> 

我沒有把真正的實現，這是該系統的只是一個簡單的例子，但它是相同的從移動

NSURL *url = [[NSURL alloc]initWithString:@"http://localhost/ws.php?id=1"]; 

NSData *dataUrl= [NSData dataWithContentsOfURL:url]; 

NSString *str = [[NSString alloc]initWithData:dataUrl 
             encoding:NSUTF8StringEncoding]; 

if(![str isEqualToString:@"0"]) 
    NSLog(@"connected"); 
else 
    NSLog(@"not connected"); 

所以

呼叫我不想使用GET方法，我只是想從使用POST手機收到我的數據，並使用這些數據發送到控制器POST也什麼是最好的解決方案？

如果您希望您的應用使用POST方法發送數據，那麼我就是這個代碼。我希望這會有所幫助。

它需要在字典對象中發送數據。 Ecodes所述要發送的數據作爲POST ，然後返回響應（如果你想以字符串格式的結果，可以用[[的NSString的alloc] initWithData：dresponse編碼：NSASCIIStringEncoding];返回數據時）

-(NSData*) getData:(NSDictionary *) postDataDic{ 

    NSData *dresponse = [[NSData alloc] init]; 

    NSURL *nurl = [NSURL URLWithString:url]; 
    NSDictionary *postDict = [[NSDictionary alloc] initWithDictionary:postDataDic]; 
    NSData *postData = [self encodeDictionary:postDict]; 

    // Create the request 
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:nurl]; 
    [request setHTTPMethod:@"POST"]; // define the method type 
    [request setValue:[NSString stringWithFormat:@"%d", postData.length] forHTTPHeaderField:@"Content-Length"]; 
    [request setValue:@"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-Type"]; 
    [request setHTTPBody:postData]; 

     // Peform the request 
     NSURLResponse *response; 
     NSError *error = nil; 

     dresponse = [NSURLConnection sendSynchronousRequest:request 
                returningResponse:&response 
                   error:&error]; 

    return dresponse; 
} 

這種方法準備字典數據POST

- (NSData*)encodeDictionary:(NSDictionary*)dictionary { 
    NSMutableArray *parts = [[NSMutableArray alloc] init]; 
    for (NSString *key in dictionary) { 
     NSString *encodedValue = [[dictionary objectForKey:key] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
     NSString *encodedKey = [key stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
     NSString *part = [NSString stringWithFormat: @"%@=%@", encodedKey, encodedValue]; 
     [parts addObject:part]; 
    } 
    NSString *encodedDictionary = [parts componentsJoinedByString:@"&"]; 
    return [encodedDictionary dataUsingEncoding:NSUTF8StringEncoding]; 
}
