【问题描述】：

我是 swift 的新手，并试图发出一个调用 api 的 http post 请求。while it works just fine on postman

这是我需要将后端作为 httpBody 的 JSON 字符串。

myJSON ="address1":"Mirpur","address2":"D6, f8","cellPhone":"01852540565","city":"fghff","countryName":"Bangladesh","orderDate":"2017-02-25T11:28:24","orderStatus":1,"orderedProductList":["discount":0.0,"orderDetailId":0,"price":30000.0,"quantity":1,"shippingCharge":50.0,"supplierId":0,"tax":0.0,"type":"isBook":false,"typeId":0,"productId":5,"productViews":0,"discount":0.0,"orderDetailId":0,"price":50000.0,"quantity":1,"shippingCharge":50.0,"supplierId":0,"tax":0.0,"type":"isBook":false,"typeId":0,"productId":8,"productViews":0,"discount":0.0,"orderDetailId":0,"price":2000.0,"quantity":1,"shippingCharge":50.0,"supplierId":0,"tax":0.0,"type":"isBook":false,"typeId":0,"productId":9,"productViews":0],"paymentTransactionId":"1215455638874521","state":"fyy","zip":"4525","countryId":23,"orderId":0,"orderTotal":82000.0,"paymentMethodId":1,"userId":0

知道如何解决这个问题，这将非常有帮助。 谢谢

【问题讨论】：

字典语法在swift中使用[]，而不是

同样在这种情况下，您需要指定变量的类型：let jsonObject: [String:Any] = ...

至于发出POST请求，试试Alamofire

我同意 deadbeef，Alamofire 强烈推荐用于 Swift 网络。

【参考方案1】：

使用 @deadbeef 建议的语法应该可以工作，例如重新格式化的 myJSON：

    let myJSON: [String : Any] = ["address1":"Mirpur",
                                "address2":"D6, f8",
                                "cellPhone":"01852540565",
                                "city":"fghff",
                                "countryName":"Bangladesh",
                                "orderDate":"2017-02-25T11:28:24",
