Reactjs 无法使用react.js和laravel更新包含formData的PUT请求

我没有在Api端点中接收由fetch and PUT方法发送的formdata

我使用了POST方法，它解决了我认为不建议更新的问题。 我在localhost:3000上运行react，在localhost:5000上运行laravelapi

这是API中的路由 这就是控制器中的内容 这是发送到fetch的函数 在我的标题中，我没有内容类型

---

我希望来自LaravelAPI函数的json数据，但我有一个错误，“只能抛出对象”

PHP不解析PUT请求的主体

---

使用

POST

并添加参数

\u方法

和值

PUT

PHP PUT给我带来了困难，使用此函数将节省解析时间，其他方法：

function parsePutRequest()
    {
        // Fetch content and determine boundary

    // Fetch each part
    $parts = array_slice(explode($boundary, $raw_data), 1);
    $data = array();

    foreach ($parts as $part) {
        // If this is the last part, break
        if ($part == "--\r\n") break; 

        // Separate content from headers
        $part = ltrim($part, "\r\n");
        list($raw_headers, $body) = explode("\r\n\r\n", $part, 2);
