如何在我的ViewController中調用httppost方法postuser並將頭文件+編碼參數傳遞給它?如何使用swift進行HTTP POST請求

Like http://www.api.com/post/data?username=kr%209&password=12 我需要在ehader中發送會話/ cookie/useragent。

request.allHTTPHeaderFields = [ 「內容類型」: 「應用/ JSON」, 「接受」: 「應用/ JSON」 ] request.addValue(mySessionToken,forHTTPHeaderField: 「SessionToken」) – jpulikkottil

當然,你可以做到這一點。如果你設法寫出你上面寫的代碼,那事情會非常簡單。只需爲需要的方法添加額外的參數,然後構建請求。 – EridB

request.setValue("Your Header value", forHTTPHeaderField: "Header-Key") //User-Agent for ex.

請注意,該類有一個sharedInstance靜態屬性?這是一個快速實施的singleton pattern。這使您可以撥打RestApiManager類的方法如下:

let postBody: [String: AnyObject] = [ 
    "username": "joe.bloggs", 
    "password": "test1234" 
] 

RestApiManager.sharedInstance.makeHTTPPostRequest(path: "relative/url", body: postBody) { json, err in 
    // Handle response here... 
} 

單例模式允許你從項目的任何地方調用類的sharedInstance實例。您不需要在viewController中創建API管理器的實例來使用它。
