Question

我在发送POST请求并获得响应时遇到问题。我已经制作了本地PHP脚本，该脚本返回了一些字符串值，但我无法使其与Xamarin一起使用。

这是我用来发送请求的方法：

public async Task<string> Post_Request()
{
    var request = new HttpRequestMessage();
    request.RequestUri = new Uri("http://localhost/server.php");
    request.Method = HttpMethod.Post;
    request.Headers.Add("Accept", "application/json");
    var client = new HttpClient();
    HttpResponseMessage response = await client.SendAsync(request).ConfigureAwait(continueOnCapturedContext: false);
    if (response.StatusCode == HttpStatusCode.OK)
    {
        return "OK";
    }
    else
    {
        return "BAD!";
    }
}

调试时，程序不会在“ if（res（seponse.StatusCode == HttpStatusCode.OK）”条件下进入if或else代码分支。

这是我的PHP脚本：

<?php
return 
"
{
"user":"01",
"name":"ime"
}
"
//echo "OK";
?>

这是我使用的示例发帖请求。

var objRequest = new CustomerDetailsRequest() {
    customerId = 1
};

string url = $"/api/v1/CustomerDetails";
var requestBody = await Task.Run(() => JsonConvert.SerializeObject(objRequest));
using (var httpClient = new HttpClient())
{
    CustomerDetailsResponse data = new CustomerDetailsResponse();
    try
    {
        httpClient.BaseAddress = new Uri("http://localhost:3000");
        var content = new StringContent(requestBody, Encoding.UTF8, "application/json");
        var result = await httpClient.PostAsync(url, content);
        var response = await result.Content.ReadAsStringAsync();
        data = JsonConvert.DeserializeObject<CustomerDetailsResponse>(response);

        if (result.IsSuccessStatusCode && result.StatusCode == HttpStatusCode.OK)
        {
            return data;
        }

        return null;
    }
    catch (Exception exp)
    {
        return null;
    }
}

让我知道这是否令人困惑
