Question

我已经做了一个api调用将产品添加到购物车。在按钮操作中我正在做这个api调用。我需要向api发送一些特定的参数。但是当我使用邮递员代码时。它在我的代码中抛出了很多错误：

func addtocartapicalling ()
{


    let headers = [
        "cache-control": "no-cache",
        "postman-token": "4c933910-0da0-b199-257b-28fb0b5a89ec"
    ]

    let postData = NSData(data: "{
        "cartType" : "1",
        "cartDetails" : {
        "customerID" : "u",
        "cartAmount" : "6999",
        "cartShipping" : "1",
        "cartTax1" : "69",
        "cartTax2" : "",
        "cartTax3" : "",
        "cartCouponCode" : "",
        "cartCouponAmount" : "",
        "cartPaymentMethod" : "",
        "cartProductItems" : {
        "productID" : "9",
        "productPrice" : "6999",
        "productQuantity" : "1"
        }
    }
}".dataUsingEncoding(NSUTF8StringEncoding)!)

var request = NSMutableURLRequest(URL: NSURL(string: "http://api.php")!,
                                  cachePolicy: .UseProtocolCachePolicy,
                                  timeoutInterval: 10.0)
request.HTTPMethod = "POST"
request.allHTTPHeaderFields = headers
request.HTTPBody = postData

let session = NSURLSession.sharedSession()
let dataTask = session.dataTaskWithRequest(request, completionHandler: { (data, response, error) -> Void in
    if (error != nil) {
        println(error)
    } else {
        let httpResponse = response as? NSHTTPURLResponse
        println(httpResponse)
    }
})

dataTask.resume()
}

看到我上面的代码，有没有api调用。请帮帮我。

由于

  let string = "{\"cartType" : "1" + "cartDetails" : { "customerID" : "u", + "cartAmount" : "6999", + "cartShipping" : "1", + "cartTax1" : "69", + "cartTax2" : "", + "cartTax3" : "", + "cartCouponCode" : "", + "cartCouponAmount" : "", + "cartPaymentMethod" : "",} + "cartProductItems" : { "productID" : "9", + "productPrice" : "6999", + "productQuantity" : "1"  }" }"

你不能只是从其他地方复制代码并期望它神奇地工作。主要问题是你不能在Swift中的多行上拆分文字字符串。将其放在一行中或在多行上添加多个文字字符串。例如......

let string = "{ \"cartProductItems\" : " +
        "{\"productID\" : \"9\"," +
        "\"productPrice\" : \"6999\"}}"

let postData = NSData(data: string.data(using: .utf8)!)

一旦您修复了大部分其他错误，您应该可以通过点击错误本身来修复，Xcode会为您修复项目NSURLSession has been renamed URLSession
