c# 没有向 PHP 发送 json 请求 [英] c# is not sending json request to PHP

问题描述

我正在尝试使用 JSON 将数据从 c# 发送到 PHP.

I am attempting to send data from c# to PHP using the JSON.

我在 PHP 页面上看到了NULL".

I see 'NULL' on the PHP page.

这是我的 c# HTTP 请求，它应该将 json 请求发送到 PHP 网页.

Here is my c# HTTP request which should send json request to PHP webpage.

        user user = new user();
        {
            user.firstname = "aaaa";
            user.secondname = "aaaaaaaaaaa";
            user.email = "aaa";
            user.phonenumber = "aaa";
        };
        string json = JsonConvert.SerializeObject(user);
        HttpWebRequest request = WebRequest.Create("https://localhost/test.php") as HttpWebRequest;
        request.ContentType = "application/json";
        //request.Accept = "application/json, text/javascript, */*";
        request.Method = "POST";
        using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
        {
            writer.Write(json);
        }
        HttpWebResponse response = request.GetResponse() as HttpWebResponse;
        Stream stream = response.GetResponseStream();

        string json1 = "";

        using (StreamReader reader = new StreamReader(stream))
        {
            while (!reader.EndOfStream)
            {
                json1 += reader.ReadLine();
            }
        }
        DisplayAlert("Alert", json1, "OK");

我有 PHPtest.php"，其中包含以下代码.

I have PHP "test.php" which has the following code.

<?php

echo json_encode($_POST);


?>

当c#函数运行时；我没有收到任何错误.

When the c# function run; I don't get any errors.

然后我刷新网页并显示NULL"

Then I refresh webpage and it says "NUll"

我想要实现的是 c# 使用 JSON 使用 REST API(HTTP 请求)发送数据.

What I would like to achieve is c# to send data using JSON using REST API (HTTP Request).

然后使用PHP；我将获取数据并保存在 MySql 表中.

Then using PHP; I will get the data and save in MySql Table.

但 PHP 只显示空"

But PHP just shows 'Null'

我做错了什么.

谢谢

编辑

我在 c# 中看到的 DisplayAlert 显示了它传递给 PHP 的字符串.

The DisplayAlert which I see in c# shows the string which it passes to PHP.

c# 传递给 PHP 的字符串警报

PHP 网页显示字符串 (0)

PHP 代码

//Receive the RAW post data.
$content = file_get_contents("php://input");

$obj = json_encode($content);



$insert_stmt = $mysqli_scs->prepare("INSERT INTO test (name,address) VALUES (?,?)");
$name =$content->{'name'};
$address = $obj->{'address'};


$insert_stmt->bind_param("ss", $name, $address);
//Execute the statement
$insert_stmt->execute();

推荐答案

你必须看看 C# 调用返回给你什么对吗?

You have to look what C# call returns to you right ?

我不懂 C#，但我不认为 json 必须在 $_POST 变量中发送，而是在请求的正文部分中发送.在香草 PHP 中，您可以通过以下方式获得它:

I don't know C# but I don't think the json must be send in the $_POST variable but in the body part of the request. In vanilla PHP you can get it with :

file_get_contents('php://input');
