Laravel 8：尝试通过 JSON Get Testing 测试控制器方法，但找不到路由

Question

我收到此错误：

预期状态码 200，但收到 404。 无法断言 200 与 404 相同。

当我尝试从我的单元测试中调用它时：

<?php

namespace Tests\Unit;

use App\Models\Project;
use Tests\TestCase;

class ExampleTest extends TestCase
{

    public function testTakePlace()
    {
        $project = Project::factory()->make();

        $response = $this->getJson('controllerUserProject_takePlace', [
            'project_id' => $project->id,
        ]);

        $response
            ->assertStatus(200)
            ->assertJsonPath([
                'project.status' => Project::STATES['TO_BE_REPLIED'],
            ]);
    }
}

但是，controllerUserProject_takePlace 是我给路线起的正确名称。确实，这里是/routing/web.php：

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\TestConnections;

use App\Http\Controllers\ControllerUserProject;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/controllerUserProject_takePlace/projects/{project_id}', [ControllerUserProject::class, 'takePlace'])->name('controllerUserProject_takePlace');

控制器ControllerUserProject 定义正确：

<?php

namespace App\Http\Controllers;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

class ControllerUserProject extends Controller
{
    public function takePlace(Request $request, $project_id)
    {
        return [
            'project_status' => Project::STATES['TO_BE_REPLIED']
        ];
    }
}

你知道为什么使用路由返回404（未找到）吗？

Answer 1

您的路由 url 是 '/controllerUserProject_takePlace/projects/{project_id}'，而在测试中您使用的是 'controllerUserProject_takePlace'，因此出现 404 错误。

getJson() 中的第二个参数也是 $headers 数组，所以当您传递 ['project_id' => $project->id] 时，它会成为第二个参数，作为 $headers。

您需要向getJson('/controllerUserProject_takePlace/projects/' . $project->id);提供完整的网址

或

由于您已经为路线命名，您可以在 getJson(route('controllerUserProject_takePlace', $project->id)); 中使用 route() 助手

更改测试中的网址

<?php

namespace Tests\Unit;

use App\Models\Project;
use Tests\TestCase;

class ExampleTest extends TestCase
{

    public function testTakePlace()
    {
        $project = Project::factory()->make();

       // $response = $this->getJson('/controllerUserProject_takePlace/projects/' . $project->id);

        //Try using named route

        $response = $this->getJson(route('controllerUserProject_takePlace', $project->id));

        $response
            ->assertStatus(200)
            ->assertJsonPath([
                'project.status' => Project::STATES['TO_BE_REPLIED'],
            ]);
    }
}
