在 C# 上使用 API 的 Amadeus 机场自动完成

Question

我在 C# 上开发应用程序，我在使用 C# 的 amadeus 库。我正在尝试获取如下所示的 AirportAutocomplete 响应：

[ { "value": "MAD", "label": "Adolfo Suárez Madrid–Barajas Airport [MAD]" } ]

由于括号内的响应不仅是 AiportAutocompleteResponse class，它更像是 AirportAutocompleteResponse class 的数组或列表。如果有更多的搜索匹配项，我将得到类似 this example.

的响应

AirportAutocompleteResponse class:

public partial class AirportAutocompleteResponse :  IEquatable<AirportAutocompleteResponse>
{
    /// <summary>
    /// Initializes a new instance of the <see cref="AirportAutocompleteResponse" /> class.
    /// </summary>
    public AirportAutocompleteResponse()
    {

    }


    /// <summary>
    /// The 3 letter IATA location code of the given city or airport. You can use this as an input parameter for a flight low-fare or inspiration search.
    /// </summary>
    /// <value>The 3 letter IATA location code of the given city or airport. You can use this as an input parameter for a flight low-fare or inspiration search.</value>
    [DataMember(Name="value", EmitDefaultValue=false)]
    public string Value { get; set; }


    /// <summary>
    /// The name of this airport, in UTF-8 format, prefixed with the name of the city if it is not already incorporated in the name of the airport, and appended with the location's IATA code (as in value), enclosed in square brackets.
    /// </summary>
    /// <value>The name of this airport, in UTF-8 format, prefixed with the name of the city if it is not already incorporated in the name of the airport, and appended with the location's IATA code (as in value), enclosed in square brackets.</value>
    [DataMember(Name="label", EmitDefaultValue=false)]
    public string Label { get; set; }



    /// <summary>
    /// Returns the string presentation of the object
    /// </summary>
    /// <returns>String presentation of the object</returns>
    public override string ToString()
    {
        var sb = new StringBuilder();
        sb.Append("class AirportAutocompleteResponse {\n");
        sb.Append("  Value: ").Append(Value).Append("\n");
        sb.Append("  Label: ").Append(Label).Append("\n");

        sb.Append("}\n");
        return sb.ToString();
    }

    /// <summary>
    /// Returns the JSON string presentation of the object
    /// </summary>
    /// <returns>JSON string presentation of the object</returns>
    public string ToJson()
    {
        return JsonConvert.SerializeObject(this, Formatting.Indented);
    }

    /// <summary>
    /// Returns true if objects are equal
    /// </summary>
    /// <param name="obj">Object to be compared</param>
    /// <returns>Boolean</returns>
    public override bool Equals(object obj)
    {
        // credit: 
        return this.Equals(obj as AirportAutocompleteResponse);
    }

    /// <summary>
    /// Returns true if AirportAutocompleteResponse instances are equal
    /// </summary>
    /// <param name="other">Instance of AirportAutocompleteResponse to be compared</param>
    /// <returns>Boolean</returns>
    public bool Equals(AirportAutocompleteResponse other)
    {
        // credit: 
        if (other == null)
            return false;

        return 
            (
                this.Value == other.Value ||
                this.Value != null &&
                this.Value.Equals(other.Value)
            ) && 
            (
                this.Label == other.Label ||
                this.Label != null &&
                this.Label.Equals(other.Label)
            );
    }

    /// <summary>
    /// Gets the hash code
    /// </summary>
    /// <returns>Hash code</returns>
    public override int GetHashCode()
    {
        // credit: 
        unchecked // Overflow is fine, just wrap
        {
            int hash = 41;
            // Suitable nullity checks etc, of course :)

            if (this.Value != null)
                hash = hash * 59 + this.Value.GetHashCode();

            if (this.Label != null)
                hash = hash * 59 + this.Label.GetHashCode();

            return hash;
        }
    }

}

我用来调用 API 的函数：

public AirportAutocompleteResponse AirportAutocomplete (string apikey, string term)
    {
         ApiResponse<AirportAutocompleteResponse> response = AirportAutocompleteWithHttpInfo(apikey, term);
         return response.Data;
    }

    /// <summary>
    /// The Airport Autocomplete API provides a simple means to find an IATA location code for flight search based on a city or airport name. The API is fully JQuery-Autocomplete compatible to enable you to quickly build a drop-down list for your users to find the right airport easily. Given the start of any word in an airport&#39;s official name, a city name, or the start of an IATA code, this API provides the full name and IATA location code of the city or airport, for use in flight searches. Only major cities and civilian airports with several commercial flights per week are included by default. The response provides up to 20 possible matches, sorted by importance, in a &lt;a href=\&quot;http://jqueryui.com/autocomplete/\&quot;&gt;JQuery UI Autocomplete&lt;/a&gt; compatible format. &lt;a href=\&quot;https://github.com/amadeus-travel-innovation-sandbox/sandbox-content/blob/master/airport-autocomplete-template.html\&quot;&gt;This sample implementation&lt;/a&gt; using JQuery UI may help. This API uses data from the OpenTravelData project, see https://github.com/opentraveldata/opentraveldata/blob/master/opentraveldata/optd_por_public.csv.\n\nThe value returned is the IATA location code. The label returned is always in UTF-8 format, with the airport official name (which is often in the native language), in the format of English City Name (if not already included in the airport name).
    /// </summary>
    /// <param name="apikey">API Key provided for your account, to identify you for API access</param> 
    /// <param name="term">Search term that should represent some part of a city or airport name.</param> 
    /// <returns>ApiResponse of AirportAutocompleteResponse</returns>
    public ApiResponse< AirportAutocompleteResponse > AirportAutocompleteWithHttpInfo (string apikey, string term)
    {

        // verify the required parameter 'apikey' is set
        if (apikey == null)
            throw new ApiException(400, "Missing required parameter 'apikey' when calling DefaultApi->AirportAutocomplete");

        // verify the required parameter 'term' is set
        if (term == null)
            throw new ApiException(400, "Missing required parameter 'term' when calling DefaultApi->AirportAutocomplete");


        var path_ = "/airports/autocomplete";

        var pathParams = new Dictionary<String, String>();
        var queryParams = new Dictionary<String, String>();
        var headerParams = new Dictionary<String, String>(Configuration.DefaultHeader);
        var formParams = new Dictionary<String, String>();
        var fileParams = new Dictionary<String, FileParameter>();
        Object postBody = null;

        // to determine the Content-Type header
        String[] httpContentTypes = new String[] {

        };
        String httpContentType = Configuration.ApiClient.SelectHeaderContentType(httpContentTypes);

        // to determine the Accept header
        String[] httpHeaderAccepts = new String[] {
            "application/json"
        };
        String httpHeaderAccept = Configuration.ApiClient.SelectHeaderAccept(httpHeaderAccepts);
        if (httpHeaderAccept != null)
            headerParams.Add("Accept", httpHeaderAccept);

        // set "format" to json by default
        // e.g. /pet/{petId}.{format} becomes /pet/{petId}.json
        pathParams.Add("format", "json");

        if (apikey != null) queryParams.Add("apikey", Configuration.ApiClient.ParameterToString(apikey)); // query parameter
        if (term != null) queryParams.Add("term", Configuration.ApiClient.ParameterToString(term)); // query parameter







        // make the HTTP request
        IRestResponse response = (IRestResponse) Configuration.ApiClient.CallApi(path_, 
            Method.GET, queryParams, postBody, headerParams, formParams, fileParams,
            pathParams, httpContentType);

        int statusCode = (int) response.StatusCode;

        if (statusCode >= 400)
            throw new ApiException (statusCode, "Error calling AirportAutocomplete: " + response.Content, response.Content);
        else if (statusCode == 0)
            throw new ApiException (statusCode, "Error calling AirportAutocomplete: " + response.ErrorMessage, response.ErrorMessage);

        return new ApiResponse<AirportAutocompleteResponse>(statusCode,
            response.Headers.ToDictionary(x => x.Name, x => x.Value.ToString()),
            (AirportAutocompleteResponse) Configuration.ApiClient.Deserialize(response, typeof(AirportAutocompleteResponse)));

    }

我想做的是从响应中检索信息，以便我以后可以使用它，这是我迄今为止尝试过的：

        string apiKey = "MyApiKey";  //Not shown for obvious reasons
        DefaultApi Amadeus = new DefaultApi("https://api.sandbox.amadeus.com/v1.2");    


        AirportAutocompleteResponse response = Amadeus.AirportAutocomplete(apiKey, "adolfo suarez");                   
        textBox3.Text = response.ToString(); 




        /**********************TRIED*************************/

        /*****USING A LIST*****/
        /*
        List<AirportAutocompleteResponse> response = Amadeus.AirportAutocomplete(apiKey, "adolfo suarez");    
        textBox3.Text = response.ToString();
        */ //Does not compile since the response its not a list



        /*****AS ARRAY*****/
        //AirportAutocompleteResponse[] response = Amadeus.AirportAutocomplete(apiKey, "adolfo suarez");   
        //textBox3.Text = response.ToString(); //Doesnt work neither



        /*****AS STRING*****/

        /*
        string response = Amadeus.AirportAutocomplete(apiKey, "adolfo suarez").ToString();    
        textBox3.Text = response.ToString();
        */ //DOESNT WORK

我得到的异常是：

'IO.Swagger.Client.ApiException' 类型的未处理异常发生在 IO.Swagger.dll 附加信息：无法将当前 JSON 数组（例如 [1, 2, 3]）反序列化为类型 'IO.Swagger.Model.AirportAutocompleteResponse'，因为该类型需要一个 JSON 对象（例如 { "name"： "value"}) 正确反序列化。要修复此错误，请将 JSON 更改为 JSON 对象（例如 { "name":"value"}）或将反序列化类型更改为数组或实现集合接口(e.g.ICollection, IList) like List 可以从 JSON 数组反序列化。 JsonArrayAttribute 也可以添加到类型以强制它从 JSON 数组反序列化。

由于 AirportAutocomplete 是 class 并且响应似乎是 AirportAutocomplete class 的列表或数组我之前提到过异常，我尝试使用列表来获取响应和数组作为上面显示但没有任何效果。我好像以前有人遇到过这个问题，他们通过

解决了这个问题

Deserialize<AiportAutocomplete>

作为

Deserialize<List<AiportAutocomplete>>

但自从我使用 APIs class 以来，我无法更改它。 ¿有没有一种方法可以解决这个问题而无需我自己的反序列化器？

抱歉延长了时间，但我想包含所有可能有帮助的信息。

Answer 1

感谢 Obito 强调这个问题，我能够重现它。正如 Rup 上面提到的，这确实是 the Swagger Specification that is used to build our client library.

中的一个错误

我已经修复了这个错误并验证它现在对我有用。如果它仍然不适合您，请告诉我们，否则请随时将此答案标记为正确 ;)
