Question

获取400错误请求尝试从我的HTTPS发布请求中获取响应时。这是我的代码：

try
{
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://coupons.valassis.eu/capi/directPrint/"+offerID);
    httpWebRequest.Credentials = new NetworkCredential(userName,Password);
    WebHeaderCollection myWebHeaderCollection = httpWebRequest.Headers;
    myWebHeaderCollection.Add("Authorization: Basic " + Convert.ToBase64String(Encoding.UTF8.GetBytes(httpWebRequest.Credentials.ToString())));

    myWebHeaderCollection.Add("x-valassis-country-code: uk");
    httpWebRequest.ContentType = "application/json";
    httpWebRequest.Accept = "application/json";
    httpWebRequest.Method = "POST";

    using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
    {
        string json = "[{ \"consumerId\": \"000000000000001\", \"remoteConsumerId\": \"000000000000001\" , \"Barcode\": \"Itf: 04910033400000000000000001,Ean13:ccode\", \"Type\": \"j\", \"returnUrl\": \"http://www.durex.co.uk\",\"CouponDescription\" : \"Coupon For:\"" + this.FirstName + " " + this.SurName + "\" }]";

        var serializer = new JavaScriptSerializer();

        streamWriter.Write(json);
        streamWriter.Flush();
        streamWriter.Close();

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (Stream streamReader =httpResponse.GetResponseStream())
        {
            using (StreamReader r = new StreamReader(streamReader))
            {
                var result = r.ReadToEnd();    

            }
        }
    }        
}
catch (WebException e)
{

}

任何人都知道可能是什么问题？或者如何解决这个问题？

您创建的JSON字符串无效，因为CouponDescription属性包含奇数引号。

如果我跑这个......

    var FirstName = "Joe";
var SurName = "Bloggs";
var json = "[{ \"consumerId\": \"000000000000001\", \"remoteConsumerId\": \"000000000000001\" , \"Barcode\": \"Itf: 04910033400000000000000001,Ean13:ccode\", \"Type\": \"j\", \"returnUrl\": \"http://www.durex.co.uk\",\"CouponDescription\" : \"Coupon For:\"" + FirstName + " " + SurName + "\" }]";

我明白了......

[{ "consumerId": "000000000000001", "remoteConsumerId": "000000000000001" , "Barcode": "Itf: 04910033400000000000000001,Ean13:ccode", "Type": "j", "returnUrl": "http://www.durex.co.uk","CouponDescription" : "Coupon For:"Joe Bloggs" }]

查看CouponFor值，报价未关闭。

LINQPad和JSONLint等工具对于验证这些情景中的代码段非常有用
