Question

当我使用他们网站上描述的Fetch API时，这是我得到的错误： TypeError: Network request failed at xhr.onload (http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:5881:8) at XMLHttpRequest._sendLoad (http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:19897:1) at XMLHttpRequest.setReadyState (http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:19887:6) at XMLHttpRequest._didCompleteResponse (http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:19782:6) at http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:19736:105 at EventEmitter.emit (http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:18050:23) at MessageQueue.__callFunction (http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:16698:23) at http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:16602:8 at guard (http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:16556:1) at MessageQueue.callFunctionReturnFlushedQueue (http://localhost:8081/index.android.bundle?platform=android&dev=true&hot=false:16601:1) 以下是触发此错误的代码：

  fetch(`${baseUrl}/basecomponents.js`)
    .then(myFunction)
    .catch(errorHandler);

我搜索了解决方案，并发现很少的主题说gzip压缩on react native在使用Fetch API时崩溃应用程序，所以我尝试了，没有任何反应。同样的错误。

然后我尝试了XMLHttpRequest API。这是代码：

  var xhttp = new XMLHttpRequest();

  xhttp.onreadystatechange = function() {
    if (xhttp.readyState == 4/* && xhttp.status == 200*/) {
      console.log(xhttp.responseText);      
    }    
  };

  xhttp.open("GET", `${baseUrl}/basecomponents.js`, true);
  xhttp.send();

这也不行。我收到"Unable to resolve host http://arbormis.loc"错误。所以我无法在Android上发出任何网络请求。请帮忙！

React Native Android网络完全被破坏了
