Sinon fakeServer failed to mock POST: 'TypeError: By RFC7230, section 3.2.4, header values should be strings. Got object'

Question

GET 方法工作正常，但使用 POST 总是会遇到问题。我的测试代码是

let server = sinon.createFakeServer();
server.respondImmediately = true;
server.respondWith(`api/v1.0/companies/${companyResponse.id}/orgchart`, [200,  {"Content-Type": "*/*"}, 'OK']);

下面是 ajax 调用：

  ajax({
    type: "POST",
    url: '/my/api/endpoint',
    data: data,
    processData: false,
    contentType: false,
    complete: this.handleLoadingComplete,
    xhr: function(){
      let xhr = $.ajaxSettings.xhr() ;
      xhr.upload.onprogress = function(evt){
        updateProgress(evt.loaded, evt.total);
      } ;
      xhr.upload.onload = function(){ console.log('loading completed') } ;
      return xhr ;
    }        
  });

使用完全相同的测试代码，当我将 ajax 方法设置为 'GET' 时，它起作用了。但是 'POST' 它总是失败。这是上面ajax的complete收到的回复 POST:

`

{ readyState: 0,
      getResponseHeader: [Function: getResponseHeader],
      getAllResponseHeaders: [Function: getAllResponseHeaders],
      setRequestHeader: [Function: setRequestHeader],
      overrideMimeType: [Function: overrideMimeType],
      statusCode: [Function: statusCode],
      abort: [Function: abort],
      state: [Function: state],
      always: [Function: always],
      catch: [Function: catch],
      pipe: [Function: pipe],
      then: [Function: then],
      promise: [Function: promise],
      progress: [Function: add],
      done: [Function: add],
      fail: [Function: add],
      status: 0,
      statusText:
       'TypeError: By RFC7230, section 3.2.4, header values should be strings. Got object' }

` 我不知道这里有什么错误，我被困了几个小时....有人可以帮忙吗？将不胜感激！

Answer 1

我有同样的问题，在我的情况下，它与 axios 的设置方式有关 headers。这不是一个真正的解决方案，但固定 sinon 并强制使用旧版本的 nise 解决了这个问题。这是一个 package.json 片段：

  ...
  "devSependencies": {
    ...
    "sinon": "^4.5.0",
    ...
  }
  ...
  "resolutions:" {
    "nise": "1.2.7"
  }
  ...

Answer 2

我遇到了同样的错误。经过大量挖掘后发现请求 headers.Hence 中缺少某些参数，ajax 正在中止请求。
