Alamofire自定义参数

问题描述：

我正试图在Swift中将此卷曲调用转换为Alamofire。Alamofire自定义参数

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\"}"

而且我想这...

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 
     }

但当然这是行不通的，它崩溃...

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()

这需要在头，而不是身体。

预期结果是采用哪种格式？ –

答

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

URL编码（目标：.queryString），标题：标题）.responseJSON

 Replace responseJSON with responseString and check your response from webservice.. it will lead to get the error line.
