在命令行中使用 curl 通过 JSON 对象发布数据

【中文标题】在命令行中使用 curl 通过 JSON 对象发布数据【英文标题】：Posting data via JSON object using curl in the command line 【发布时间】：2019-10-21 15:59:57 【问题描述】：我正在尝试通过命令行将数据从一台服务器发布到另一台服务器。最终，我将使用真实数据，但现在我只想测试它是否有效，但它没有。
在 server1 的命令行中，我使用 curl 通过 JSON 发送数据，而在我的其他服务器中，我有一个方法可以接收 JSON 对象，对其进行解码并打印出来，但是这里有问题。
不发送 JSON 对象，一切正常：我可以打印“例句”，这表明我的方法正在被访问并且有效。
但是，当我发送 JSON 对象时，它会打印我的 .env 文件中的所有详细信息，而我发送的对象中没有任何内容，我不明白。
我尝试过用很多不同的方式编写 curl，但似乎没有任何效果。
来自服务器 1 的卷曲：
curl -X POST -H "Content-Type: application/json" \
-d '"orderId":12345,"customerNr":98765' \
https://returns.jdoe.blah.test/createReturn
来自服务器 2 上 web.php 的路由：
Route::post('/createReturn', 'ProductReturnsController@createReturn');
来自服务器 2 上控制器 ProductReturnsController.php 的方法：
public function createReturn($json)
echo "hallo\n";
$jsonDecoded = json_decode($json);
echo $jsonDecoded->orderId;
print_r($jsonDecoded);
//return view('data');
我现在已将视图注释掉，因为我想确保我可以先发送和接收 JSON 对象。
我在命令行运行curl后的输出如下：

当我传递 orderId 时，我希望在回显 orderId 时看到“12345”。
谁能解释我做错了什么？
编辑： 当我运行以下命令并且我没有在 createReturn 中解码 JSON 时，它会按预期在控制台中打印“hallo”：
curl --header "Content-Type: application/json" \
--data '"orderId":12345,"customerNr":98765' \
https://returns.jdoe.blah.test/createReturn
但是，当我运行上面的 curl 并尝试在 createReturn 中解码 JSON 时，它会打印上面提到的整个 html 文件。所以它似乎与JSON解码有关，也许？
【问题讨论】：
可能是个愚蠢的问题，但您是否在请求周期的早期检查过您不是dump-ing 您的.env？我看到数据有 sf-dump 类等，据我所知，这来自使用 symfony dump 命令，而不是 print_r。简而言之，您是否真的看到脚本打印了您的echo "hallo\n"; 行？
@Kyrre 我如何知道我是否在请求周期的早期转储了 .env 文件？这听起来很愚蠢，但据我所知，我正在调用 uri /createReturn，它进入我的控制器 ProductReturnsController，然后调用函数 createReturn，它应该做的就是回显“你好”。
@Kyrre 另外，我刚刚删除了 json 对象并运行： curl -X POST returns.jdoe.blah.test/createReturn 它再次给了我整个 html 文件。但是昨天当我在没有 JSON 对象的情况下运行命令时，它工作并打印了“hello”。我不知道它为什么会改变。
我会在整个项目范围内搜索dump 函数，然后从ìndex.php（或app/app_dev.php，取决于您的Symfony 版本）开始处理请求。除此之外，很抱歉我不能提供更多帮助..不知道curl的来龙去脉>_>
@Kyrre 谢谢:)。我现在将继续进行项目范围的搜索。顺便说一句，我刚刚尝试了 curl returns.jdoe.blah.test/createReturn 没有 GET 或 POST 并且它按预期打印了“你好”。我不知道为什么 POST 不起作用。
【参考方案1】：
我发现我做错了什么:)。
我将卷曲改为：
curl -i -H "Accept: application/json" \
--data '"orderId":"12345", "customerNr":"98765"' \
-H "Content-Type: application/json" \
-X POST https://returns.jdoe.blah.test/createReturn
我在 ProductReturnsController.php 中将我的方法编辑为：
public function createReturn(Request $request)
$arr = $request->all();
foreach ($arr as $value)
echo "Current value is: " . $value . "\n";
我的问题是我只是使用 $json 作为参数，但我需要使用 Request $request 对参数进行类型提示，然后访问 $request 以获取存储在 JSON 对象中的信息。
例如，如果我只想访问 orderId，就像我在上面的问题中尝试的那样，我可以使用 input() 而不是 all()： p>
public function createReturn(Request $request)
$orderId = $request->input('orderId');
echo "The order id is: " . $orderId . "\n";
希望这可以帮助其他人，如果他们遇到同样的问题。
