Question

我需要验证JSON有效内容以包含特定字段的JSON对象。据我所知，在Laravel的#include <iostream> using namespace std; struct B{ const char mem_var[]; }; struct A { const char * value_in_struct ; // this line gives me a error message. A(char *s):value_in_struct(s){} A() { value_in_struct = NULL;} }; void t(void) { const char value[] = "att"; // this line was ok at compiling std::cout << "value = " << value << std::endl; //value[2] = 's'; // gives error } int main(){ A a(const_cast< char *>("abc")); A b ; b.value_in_struct = "bbc"; cout <<"a: "<<a.value_in_struct << endl; cout <<"b: "<<b.value_in_struct << endl; t(); //B bb; gives error for not initizaling mem_var return 0; }

中，JSON对象和JSON数组都转换为PHP数组

请参阅下面的示例。

Controller.php这样

Illuminate\Http\Request

private static function getType($o) { if (is_object($o)) { return "Object"; } else if (is_array($o)) { return "Array"; } return "Unknown"; } public function test(Request $request) { $input = $request->all(); $response = []; foreach ($input as $key => $value) { $response[$key] = Controller::getType($value); } return response()->json($response); }是获取HTTP请求命中的函数。

以下是来自 Controller.php

的示例请求和响应

请求

test

响应

{
    "obj1": {},
    "obj2": {
        "hello": "world"
    },
    "arr1": [],
    "arr2": ["hello world"]
}

我是否可以在此处验证字段{ "obj1": "Array", "obj2": "Array", "arr1": "Array", "arr2": "Array" }和obj1仅包含 JSON对象？

Laravel的Illuminate\Http\Request使用

解码json函数中的JSON请求

json_decode($this->getContent(), true)

将true用于第二个参数$assoc会使json_decode将所有对象转换为关联数组。

我对 Controller.php

进行了以下更改

$input = $request->all();

已更改为

 $input = json_decode($request->getContent());

以下是已修改 Controller.php

的示例请求和响应

请求

{ "obj1": {}, "obj2": { "hello": "world" }, "arr1": [], "arr2": ["hello world"] }

<强>响应

{ "obj1": "Object", "obj2": "Object", "arr1": "Array", "arr2": "Array" }

在Laravel中区分JSON对象和JSON数组
