具有多個參數的RestKit身份驗證

我無法通過身份驗證來使用PHP堆棧上的REST API。允許登錄在瀏覽器上工作的查詢字符串看起來像...我遵循RestKit上的所有可用文檔，並且提供了下面的代碼，除了啓用NSLogConfigure之外，其輸出還在代碼之後。代碼具有多個參數的RestKit身份驗證

- (void)sendHTTPAuthRequestWithParams { 
NSMutableDictionary* authParams = [[NSMutableDictionary alloc] init]; 
NSMutableDictionary* moreParams = [[NSMutableDictionary alloc] init]; 

//user and password params 
[authParams setObject:usernameTextField.text forKey:@"login"]; 
[authParams setObject:passwordTextField.text forKey:@"password"]; 

//more parameters for rest login api 
[moreParams setObject:@"Login" forKey:@"module"]; 
[moreParams setObject:@"mylogin" forKey:@"action"]; 
[moreParams setObject:authParams forKey:@"params"]; 

//parsing 
id<RKParser> parser = [[RKParserRegistry sharedRegistry] parserForMIMEType:RKMIMETypeJSON]; 
NSError *error = nil; 
NSString *json = [parser stringFromObject:moreParams error:&error]; 

[RKClient sharedClient].authenticationType = RKRequestAuthenticationTypeHTTP; 

//if no error 
if(!error) {   
    RKLogConfigureByName("RestKit/Network", RKLogLevelTrace); 
    [[RKClient sharedClient] post:@"/index.php?" params:[RKRequestSerialization serializationWithData:[json dataUsingEncoding:NSUTF8StringEncoding] MIMEType:RKMIMETypeJSON] delegate:self]; 
    RKLogConfigureByName("RestKit/Network", RKLogLevelTrace); 
}  
//[[RKClient sharedClient] post:@"/index.php?module=Login&action=mylogin" params:authParams delegate:self]; }

RKLogConfigureByName（）輸出

你可以從日誌中看到，查詢字符串（認證參數）包含在HTTP主體。那很好嗎？另外，我確實得到了http響應狀態代碼200（OK），但是我只能看到index.html網頁生成的整個HTML代碼。不知道我去哪裏錯了？我如何解譯RestKit響應？

您是否嘗試將所有參數作爲路徑變量上的簡單字符串發送？作爲對此的迴應，你會得到什麼？ – clopez

我試過這樣做，並且工作正常...但是，我必須硬編碼身份驗證值。 – rajeshvenkat

您的代碼無法正常工作，因爲您正在將模塊和操作發送爲POST值而不是GET。您可能會收到相同的html代碼，就好像您會向index.php發送無params請求一樣。如果你願意，你可以嘗試你的代碼並捕獲整個HTML響應，並將其與index.php網頁上的HTML響應進行比較，沒有參數，我敢打賭他們是一樣的。

我沒有測試代碼，但不妨一試：

- (void)sendHTTPAuthRequestWithParams { 

    NSString *loginPath = [NSString stringWithFormat:@"index.php?module=%@&action=%@",@"Login",@"myModule"]; 

    NSMutableDictionary* authParams = [[NSMutableDictionary alloc] init]; 
    [authParams setObject:usernameTextField.text forKey:@"login"]; 
    [authParams setObject:passwordTextField.text forKey:@"password"]; 

    [[RKClient sharedClient] post:loginPath usingBlock:^(RKRequest *request) { 
     request.authenticationType = RKRequestAuthenticationTypeHTTP; 
     request.method = RKRequestMethodPOST; 
     request.params = authParams; 
     request.delegate = self; 
     request.onDidLoadResponse = ^(RKResponse *response){ 
      if (response.statusCode > 299) { 
       //We got an error! 
      }else { 
       //Check Response Body to get Data! 
      } 
     }; 

    }]; 
}

在響應體，你會得到一個NSData，如果你希望在響應JSON可以變換到一個NSDictionary與此：NSData to NSDictionary from JSON

RK的主要缺點是，它缺乏良好的文檔，這裏有一些東西，你可以看看，瞭解一些基本知識：

可以看到另一種方式，有點更先進的，這樣做的你想用什麼RKObjectM應用RestKit：Making a post to API with RKParams and mapping the response with RKObjectMapping using RestKit。

最後，你也可以檢查這個代碼，它描述瞭如何Do a simple json POST using RESTKit

你也可以問RestKit的開發者在Twitter上。這對我來說非常好，他們回答得非常快！

謝謝，@clopez，這對我來說非常合適。我仍然有點困惑，爲什麼我的原始代碼不起作用。是的，我也認爲RKObjectMapping應該適用於高級查詢。 – rajeshvenkat

我會更新我的回答以回答這個問題，如果你願意，請記住給我回答:) – clopez

我可以問一個後續問題嗎？你如何在NSMutableDictionary中包含一個多形式的圖像？ http://stackoverflow.com/questions/11189120/include-image-using-nsmutabaledictionary-with-rkclient-and-receiving-on-the-php/11190451#comment14704769_11190451 – ruelluna
