Question

在具有rest架构的spring boot应用程序中

我尝试做一个ajax调用

jQuery.ajax({
    type: "PATCH",
    url: getHostName() + "/members/" + memberId + "/contracts/" + contractId + "?status=CANCEL",
    contentType: "application/json",
    dataType: 'json',
    headers: {
      "Authorization": "Basic " + $.cookie('authorization')
    },
    success: function (data, status, jqXHR) {
      $('#modalSaveSuccess').modal('show');
    },
    error: function (jqXHR, status) {
      checkError(jqXHR);
    }
});

在控制器中，

 @PatchMapping(value = "/members/{memberId}/contracts/{contractId}")
 public ResponseEntity updateContractStatus(@PathVariable("memberId") Long memberId, @PathVariable("contractId") Long contractId, @RequestParam("status") StatusEnum status) {

     if (status == StatusEnum.CANCEL) {
         contractService.cancelContract(contractId);
     }
     return new ResponseEntity(HttpStatus.OK);
 }

当我调试时，我看到返回HttpStatus.OK

在javascript中进入错误部分，状态为200且状态为文本＆＃34; parsererror＆＃34;

Answer 1

您已设置dataType: 'json'，但您没有返回json。请删除该行并检查结果。

使用jquery无法正确处理控制器的响应
