【问题标题】:How to post raw data as a parameters in Alamofire?如何在 Alamofire 中将原始数据作为参数发布?

【问题描述】:

如何在 Alamofire 中发布这种形式的参数?

[{"view_id":"108","Class_id":"VIII"}]

像往常一样Alamofire 接受 [String:Any] 参数,当我在Alamofire 请求中输入此参数时,它会引发错误:

"extra call method"

    【解决方案1】:

    你说As normally Alamofire accept [String:Any] parameters,然后你传递了[[String: Any]]

    尝试在 hhtpBody 中传递您的数据。

    let urlString            = "yourString"
    guard let url = URL(string: urlString) else {return}
    var request        = URLRequest(url: url)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    do {
        request.httpBody   = try JSONSerialization.data(withJSONObject: your_parameter_aaray)
    } catch let error {
        print("Error : \(error.localizedDescription)")
    }
    Alamofire.request(request).responseJSON{ (response) in
    }

    • 已解决,谢谢
    【解决方案2】:

    您可以使用自定义编码来发送请求中的参数。检查Alamofire docs on custom-encoding

    struct JSONStringArrayEncoding: ParameterEncoding {
        private let jsonArray: [[String: String]]
    
        init(jsonArray: [[String: String]]) {
            self.jsonArray = jsonArray
        }
    
        func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
            var urlRequest = try urlRequest.asURLRequest()
    
            let data = try JSONSerialization.data(withJSONObject: jsonArray, options: [])
    
            if urlRequest.value(forHTTPHeaderField: "Content-Type") == nil {
                urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
            }
    
            urlRequest.httpBody = data
    
            return urlRequest
        }
    }
    

    使用方法:

    Alamofire.request("https://myserver.com/api/path", method: .post, encoding: JSONStringArrayEncoding).responseJSON { response in
    
    }

      试试这个方法来解决:

      Alamofire.request(url, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: header).validate(statusCode: 200..<300) .responseJSON { response in
                  
      
      }
