Alamofire自定义参数

我正在尝试将这个curl 调用转换为Swift 中的Alamofire。

 curl -X POST https://content.dropboxapi.com/2/files/download    
     --header "Authorization: Bearer ab-xxx-x-x"     
     --header "Dropbox-API-Arg: {\"path\": "/acme101/acmeX100/acmeX100.001.png\"}"

我想到了这一点...

let headers:HTTPHeaders = ["Authorization": "Bearer " + token2Save]
let moreheaders:Parameters = ["Dropbox-API-Arg": ["path":sourcePath]]

Alamofire.request("https://content.dropboxapi.com/2/files/download", parameters: moreheaders, encoding: URLEncoding(destination: .queryString), headers: headers).responseJSON { feedback in
        guard feedback.result.value != nil else {
            print("Error: did not receive data", print("request \(request) feedback \(feedback)"))
            return
        }

但当然它不起作用，它崩溃了......

request (Function) feedback FAILURE: responseSerializationFailed(Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.}))
Error: did not receive data ()

这需要位于标题中，而不是正文中。

let headers:HTTPHeaders = ["Authorization": "Bearer " + token2Save]
let moreheaders:Parameters = ["Dropbox-API-Arg": ["path":sourcePath]]

Alamofire.request("https://content.dropboxapi.com/2/files/download", parameters: moreheaders, encoding: URLEncoding(destination: .queryString), headers: headers).responseJSON { feedback in
        guard feedback.result.value != nil else {
            print("Error: did not receive data", print("request \(request) feedback \(feedback)"))
            return

URLEncoding(目的地: .queryString), headers: headers).responseJSON

将responseJSON 替换为responseString 并检查来自webservice 的响应..这将导致出现错误行。
