Alamofire HTTP请求失败

Question

我使用Alamofire发出了一些HTTP请求。 某些请求已成功，某些请求失败。

错误是Invalid value around character 0.

请求失败给了我以上错误。

在下面，我提到了一个失败的示例代码。

let parameters = ["amount": ["10"], "payment_method": ["paypal"], "date": ["2015-11-25"], "details": ["Payment description"]]

    let headers = [
        "Accept": "*/*",
        "Content-Type": "application/json"
    ]

    let url = "https://livetest.somedomain.com/api/invs/LAT1j5da99PdPg/payments?auth_token=pbtTEPNki3hUhGBuPX3d"

    Alamofire.request(.POST, url, parameters: parameters, encoding: .JSON, headers: headers)
        .responseJSON { response in
            let results = response.result
            print(results)
            print(response.debugDescription)
    }

请帮我找到问题

Answer 1

发生此问题是因为JSON传递的格式错误。 然后我如下更改参数

let parameters = ["payment":["amount": "100" , "payment_method": "check", "date": "2015-11-25", "details": "Payment description dimuth Lasantha"]]

现在，它传递的正确格式是

{
payment: {
    "amount" : "100",
    "payment_method" : "check",
     .....
    }
}
