Laravel API - JSONP response returns 500 Internal Server Error
提问by LoveAndHappiness
I am working on a Laravel API. My web application is making a GETrequest to my API. But because the API is set to a subdomain (http://api.geladaris.dev/v1/books), I have to use JSONPto make Cross-Origin GETrequests work to this endpoint.
我正在研究 Laravel API。我的 Web 应用程序正在GET向我的 API发出请求。但是因为 API 设置为子域 ( http://api.geladaris.dev/v1/books)，所以我必须使用JSONP使跨域GET请求工作到此端点。
On the client side I have a polymerelement, that generates the GETrequest and the server should return a jsonpresponse by Laravel.
在客户端，我有一个polymer元素，它生成GET请求，服务器应该jsonp通过 Laravel返回响应。
The Laravel documentation herestates, that the setCallbackmethod is to be chained to the response like this:
此处的 Laravel 文档指出，该setCallback方法将像这样链接到响应：
return response()
->json(['name' => 'Abigail', 'state' => 'CA'])
->setCallback($request->input('callback'));
And that is what my indexmethod on my Api\BooksControllerlooks like:
这就是我的index方法的Api\BooksController样子：
public function index()
{
return response()
->json(['name' => 'Abigail', 'state' => 'CA'])
->setCallback($request->input('callback'));
}
And my Routes.php
和我的 Routes.php
Route::group(['domain' => 'api.geladaris.dev'], function () {
Route::group(['prefix' => 'v1'], function () {
Route::resource('books', 'Api\BooksController');
});
});
Unfortunately, all I get is a 500 Internal Server Error, when the request is generated and the server returns above code, with the "setCallback" method:
不幸的是500 Internal Server Error，当生成请求并且服务器使用“setCallback”方法返回上述代码时，我得到的只是一个：
This only happens, if I use the setCallbackMethod. If I omit it, and return a normal jsonresponse instead of jsonp, the file is found, but I don't get the parseResponseI get, when accessing another API, f.e. http://api.github.com/usersor http://jsonplaceholder.typicode.com/posts. Notice the very first line:
这只会发生，如果我使用setCallback方法。如果我省略它，并返回一个正常的json响应而不是jsonp，找到文件，但我没有得到parseResponse我得到的，当访问另一个 API 时，fe http://api.github.com/users或http:// jsonplaceholder.typicode.com/posts。注意第一行：
I am not sure how to proceed from here on. I have disabled the CSRFMiddleware and run my routes without any Middleware.
我不知道如何从这里开始。我已禁用CSRF中间件并在没有任何中间件的情况下运行我的路线。
I also tried using the apimiddleware, witout any positive results.
我也尝试使用api中间件，但没有任何积极的结果。
My next aproach would be to install a CORSlibrary and try setting the right response headers, but I doubt that the problem will be found there, since I checked and compared the headers from three different API's (Google News, Github, Json Placeholder) to my API and the only substantial difference I found, was the missing parseResponsebefore the actual returned JSON.
我的下一个方法是安装一个CORS库并尝试设置正确的响应标头，但我怀疑是否会在那里找到问题，因为我检查并将来自三个不同 API（Google 新闻、Github、Json Placeholder）的标头与我的API 和我发现的唯一实质性区别是parseResponse在实际返回的 JSON 之前丢失了。
Therefore I wonder: How do I set the JSONPresponse in Laravel to be found and not return 500 Server error?
因此我想知道：如何JSONP在 Laravel 中设置响应而不返回 500 服务器错误？
Since the error indicates a Server Error, here some details to the server:
由于错误表示服务器错误，这里有一些关于服务器的详细信息：
I am using WAMP.
我正在使用 WAMP。
My vhost:
我的vhost：
<VirtualHost *:80>
DocumentRoot "d:/wamp/www/geladaris/public"
ServerName geladaris.dev
ServerAlias *.geladaris.dev
</VirtualHost>
My hostsfile:
我的hosts文件：

Turns out that
结果是
return response()
->json(['name' => 'Abigail', 'state' => 'CA'])
->setCallback($request->input('callback'));
Just required the Request to be put through the index method like this:
只需要像这样通过索引方法提交请求：
public function index(Request $request)
{
return response()
->json(['name' => 'Abigail', 'state' => 'CA'])
->setCallback($request->input('callback'));
}
