Question

我正在尝试发送一个如下所示的api请求：

https://api.gibbly.com/1/device?format=json&body= {“ selection” = {“ selectionType”：“已注册”，“ selectionMatch”：“”，“ includeRuntime”：true}}

但是，当我使用下面的代码时，出现错误。在响应的[RESULT]部分中，我得到以下信息：

[RESULT] FAILURE: responseSerializationFailed(reason: Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(error: Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.}))

我尝试使用Postman进行请求，并且效果很好，所以我认为问题是由代码引起的。

基于代码中的第一个“ print”语句，HTTP正文似乎是正确的：

Optional({"selection":{"selectionType":"registered","selectionMatch":"","includeSettings":true}})

我唯一能想到的是Alamofire并未在请求中添加“ format = json＆body =“，但我不知道该如何看待。任何帮助将不胜感激。


        let headers: HTTPHeaders = [
            "Authorization": "Bearer adsf023494axadf32342",
            "Content-Type": "text/json"
        ]

        let parameters: [String: Any] = [
            "selection":[
                "selectionType":"registered",
                "selectionMatch":"",
                "includeSettings":true
            ]
        ]

        Alamofire.request(url!, method: .get, parameters: parameters, encoding: JSONEncoding.default, headers: headers).responseJSON {
            response in
print(NSString(data: (response.request?.httpBody)!, encoding: String.Encoding.utf8.rawValue))
            print(response)
        }

Answer 1

对于GET方法，在Alamofire请求中使用URLEncoding.default而不是JSONEncoding.default

Answer 2

好了。我做了以下工作：（1）将参数创建为字符串，（2）对它们进行百分比编码，以便所有字符都可以用作url，（3）将编码后的参数添加到基本url，以及（4）使用新网址，其中包含基本网址，然后将编码后的参数作为我请求的网址。

let url = "https://api.gibbly.com/1/device?format=json&body="
        let urlParams = "{\"selection\":{\"selectionType\":\"registered\",\"selectionMatch\":\"\",\"includeSettings\":true}}"
        let urlEncoded = url + urlParams.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)!

        let headerList : HTTPHeaders = [
            "Authorization" : "Bearer " + (KeychainWrapper.standard.string(forKey: "accessToken"))!, 
            "Content-Type" : "text/json"
        ]

        Alamofire.request(urlEncoded, method: .get, headers: headerList).responseJSON{
            response in
print(response)
}

使用Alamofire格式化HTTP请求“ format = json＆body =”
