org.apache.coyote.http11.Http11Processor.service解析HTTP请求标头时出错

Question

我收到此错误

org.apache.coyote.http11.Http11Processor.service Error parsing HTTP request header
 Note: further occurrences of HTTP header parsing errors will be logged at DEBUG level.
 java.lang.IllegalArgumentException: Invalid character found in method name. HTTP method names must be tokens

我有一个应用https://test.com，我打电话给后端服务器，从亚马逊s3云存储中检索文件。后端呼叫为https://backend.com/api/getFile

弹簧启动控制器的示例

@RequestMapping(value = "/api/getFiles", method = RequestMethod.POST)
    public ResponseEntity<?> getAllFules(@RequestBody String test){
        try{
            //some code
            return new ResponseEntity<Object>("ok", HttpStatus.OK);
        }catch(Exception e){
            return new ResponseEntity<Object>("not ok", HttpStatus.BAD_REQUEST);
        }
    }

后端服务器运行的nginx路由到proxy_pass http://127.0.0.1:8080/

客户端http代码在angular

中是这样的

$http({
            url: 'https://www.backend.com/api/getFiles',
            method: "POST",
            data: auth.profile['email']
        })
        .then(function(response) {
            console.log(" post success get files");



        },
        function(response) { // optional
            // failed
            console.log("post failed get files");

        })
