java - 如何制作一个 Controller 来使用HashMap获取URL？

Question

我需要在 Spring Boot 2.0 中创建一个 Controller 才能正确获取如下 URL:

https://localhost:8443/my_generate_signature?data%5Btimestamp%5D=1570074358&data%5Bsource%5D=uw

此 URL 正在由 AJAX 请求调用:

<script type="text/javascript">
var generateSignature = 
function(callback, params_to_sign){
$.ajax({
url     : "/my_generate_signature",
type    : "GET",
dataType: "text",
data    : { data: params_to_sign},
complete: function() {console.log("complete")},
success : function(signature, textStatus, xhr) { callback(signature); },
error   : function(xhr, status, error) { console.log(xhr, status, error); }
});
}
</script>

<script type="text/javascript">  
  $('#upload_widget_opener').cloudinary_upload_widget({ 
    cloudName: cloudName, apiKey: api_key,
    cropping: true, uploadSignature: generateSignature}, (error, result) => { });
</script>

作为引用，我正在尝试实现这个:

https://cloudinary.com/documentation/upload_widget#create_upload_widget_methods

我尝试过这样的 Controller ，但我得到 HttpStatus 400:

@RequestMapping(value="/my_generate_signature")
@ResponseBody
public String generateSignature(@RequestParam(value="params_to_sign", required=true) Map<String, Object> paramsToSign) {

return 'test';
}

您还可以使用发布请求并使用请求正文。@PostMapping@ResponseBody公共(public)字符串generateSignature(@RequestBody Map> paramsToSign){ 返回 ”....”;}

如果是get请求，可以使用@GetMapping和@RequestParam注解。
