和我的.svc.cs代码：

    public class api
    {
        [OperationContract]
        public void DoWork()
        {
            return;
        }

        [OperationContract]
        [WebInvoke(Method           = "GET",
                   UriTemplate      = "SAutomationOptions/getall",
                   ResponseFormat   = WebMessageFormat.Json,
                   RequestFormat    = WebMessageFormat.Json,
                   BodyStyle        = WebMessageBodyStyle.Bare)]
        public async Task<ChromeExtData> getall()
        {
            ChromeExtData _chromeExtData = new ChromeExtData();

            using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["DBConnectionString"].ToString()))
            {
                await conn.OpenAsync();
                _chromeExtData              = await conn.QuerySingleAsync<ChromeExtData>("SELECT * FROM SAutomationOptionsSSRCC", null);
            }

            return _chromeExtData;
        }

        [OperationContract]
        [WebInvoke(Method = "POST", 
                   UriTemplate = "SAutomationOptions/fnumber/{FNum}",
                   RequestFormat = WebMessageFormat.Json,
                   ResponseFormat = WebMessageFormat.Json,
                   BodyStyle = WebMessageBodyStyle.Bare)]
        public async Task<ChromeExtData> FNum(String FNum)
        {
            ChromeExtData _chromeExtData = new ChromeExtData();

            using (SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["DBConnectionString"].ToString()))
            {
                await conn.OpenAsync();
                _chromeExtData = await conn.QuerySingleAsync<ChromeExtData>(
                                            "SELECT * FROM SAutomationOptionsSSRCC WHERE fnum = @fNum", 
                                            new { fNum = FNum }
                                       );
            }

            return _chromeExtData;
        }
    }
}

当我将GET加载到浏览器http://localhost:56784/api.svc/SAutomationOptions/getall中时：

{"birthday":"5\/21\/2019","code":"qTest","cstatus":"F","ethnicity":"Latino","ffl":"14774123","fname":"Bob","fnum":"5510471","lname":"Barker","miscnumbers":"645","mname":"Showcase","noty":"True","numsr":"514","pob":"TN","race":"American, Native Hawaiian","sex":"M","sor":"AZ","transp":"Redemption, Redemption of This"}

我期望它是输出。

但是，当我尝试执行POST http://localhost:56784/api.svc/SAutomationOptions/fnumber/15263时，我得到：

enter image description here

也使用以下JS代码在Ajax上进行测试：

function ajaxPostData() {
    $.ajax({
        url: 'http://localhost:56784/api.svc/SAutomationOptions/fnumber/15263',
        type: 'POST',
        data: JSON.stringify({"FNum": 15263}),
        dataType: 'json',
        contentType: "application/json; charset=utf-8",
        success: function (data, textStatus, jqXHR) {
            console.log(data);
        },
            failure: function (response) {
            alert(response.d);
        },
        error: function (jqXHR, textStatus, errorThrown) {
            console.log("error: ", jqXHR);
        }
    });
}

恢复错误：

  

POST http://localhost:56784/api.svc/SAutomationOptions/fnumber/15263 400（错误请求）

     

statusText：“错误请求”

我确定它与Web.Config文件有关，但是我只是不知道它可能是什么？

1 个答案:

答案 0 :(得分：0)

我试图重现您的问题，但失败了。在我这方面，结果可以正确返回。我怀疑查询语句有问题。您确定请求会得到正确的回复吗？我建议您返回一个硬代码对象以排除此错误。
此外，如果此问题与CORE有关，建议您删除ContentType或将其更改为以下内容。

contentType: 'application/x-www-form-urlencoded'

请随时告诉我是否有什么可以帮忙的。
