Reactjs 正在获取200状态代码，但react中未定义响应

响应中没有文本道具。您可以选择console.log response.items.length

{"kind":"analytics#accounts","username":"avisha1997.ab@gmail.com","totalResults":1,"startIndex":1,"itemsPerPage":1000,"items":[{"id":"106194863","kind":"analytics#account","selfLink":"https://www.googleapis.com/analytics/v3/management/accounts/106194863","name":"My Life Jobs","permissions":{"effective":[]},"created":"2017-09-11T06:39:57.512Z","updated":"2017-09-11T06:42:02.258Z","childLink":{"type":"analytics#webproperties","href":"https://www.googleapis.com/analytics/v3/management/accounts/106194863/webproperties"}}]}

请彻底参阅此链接

这样更正确。没有请求参数，只有响应参数，这是任何承诺的第一个也是唯一的参数。得到了响应..谢谢！

{"kind":"analytics#accounts","username":"avisha1997.ab@gmail.com","totalResults":1,"startIndex":1,"itemsPerPage":1000,"items":[{"id":"106194863","kind":"analytics#account","selfLink":"https://www.googleapis.com/analytics/v3/management/accounts/106194863","name":"My Life Jobs","permissions":{"effective":[]},"created":"2017-09-11T06:39:57.512Z","updated":"2017-09-11T06:42:02.258Z","childLink":{"type":"analytics#webproperties","href":"https://www.googleapis.com/analytics/v3/management/accounts/106194863/webproperties"}}]}

console.log(response.items.length);

queryAccounts() {
    console.log('inside queryAccounts');
    gapi.client.load('analytics', 'v3').then(function() {
    gapi.client.analytics.management.accounts.list()
    .then(function(response){
      console.log(response); // try consoling and you will we able to see the response. response is the first arguments not the request
      if (response.items && response.items.length) {
    // Get the first Google Analytics account.
    var firstAccountId = response.items[0].id;
    console.log(firstAccountId);
  }
  else {
    console.log('No accounts found for this user.');
  }
});
