ios - Swift 5 & Alamofire 5 : GET method ERROR: Alamofire. AFError.URLRequestValidationFailureReason.bodyDataInGETRequest(22 字节)

Question

我正在尝试使用 Alamofire 从数据库中获取记录。我在 GET 请求中发送参数如下。

let headers : HTTPHeaders = ["x-access-token": "\(t)","username":"\(Base.sharedManager.user)","password":"\(Base.sharedManager.pass)"]
let parm : [String: Any] = ["search_str" : self!.searchStr]
// let searchUrl = Base.sharedManager.URL+"questions/get/"+self!.searchStr
let searchUrl = Base.sharedManager.URL+"questions/get/"

AF.request(searchUrl, method: .get, parameters: parm, encoding:JSONEncoding.default , headers: headers, interceptor: nil).response { (responseData) in
    guard let data = responseData.data else {
        debugPrint("Error getting question data", responseData.error as Any)
        self?.showNoResults()
        return
    }

    do {
        let sResults = try JSONDecoder().decode(SearchResults.self, from: data)
        self!.searchReturn = [sResults]
        self!.qSearchTV.reloadData()
    } catch {
        self?.showNoResults()
        print("Error retriving questions \(error)")
    }                        
}

执行上述代码时出现以下错误:
“获取问题数据时出错”可选(Alamofire.AFError.urlRequestValidationFailed(原因:Alamofire.AFError.URLRequestValidationFailureReason.bodyDataInGETRequest(23 字节)))

Answer 1

使用URLEncoding.default而不是 JSONEncoding.default

AF.request(path, 
          method: .get, 
      parameters: params, 
        encoding: URLEncoding.default, 
         headers: nil)
  .response { (responseData) in

}
