在 PHP 中使用 ENTER 在字段值之一中接收 JSON POST

Question

当“描述”字段具有“输入”（换行符）时，API 失败。

用于检查用户发送的所有参数的图像

下面的代码从发布的 JSON 中获取数据。

     // get posted data

     $jason_value = json_decode(file_get_contents("php://input"));

     $crm_id = $jason_value->data->crmId;

     $descriptions = $jason_value->data->descriptions;

我想接受描述作为字符串一行。

descriptions = "10+ windows 现代风格 7057655959"。

我无权访问用户输入描述的程序，我可以在其中添加验证并将其转换为 \n。

转换后低于字符串

你是对的，在 PHP7+ 中，文字制表符或换行符会导致 json 解析失败。file_get_contents("php://input")返回一个字符串，所以我看不出为什么你不能在尝试解析它之前过滤它。但也许我错过了一些东西。//Catch Unix OR DOS line endings, but not both$filter = Array("\n","\n\r");$replace = " ";$cleanJSON = str_replace($filter, $replace, file_get_contents("php://input");$data = json_decode($cleanJSON));我想指出，在这一点之后，您的代码引用了一个不存在的变量： $jason_value$crm_id = $jason_value->data->crmId;$descriptions = $jason_value->data->descriptions;要引用您刚刚创建的对象的属性，请直接转到$data：$crm_id = $data->crmId;$descriptions = $data->descriptions;我希望您想用空格替换换行符，但如果您实际遇到的内容在换行符之前有一个空格，则您可能只想要一个空字符串，但无法从我们拥有的内容中看出这一点。
