title: Network request failed while fetch the data from wen URL
body: <p>I am new in react native and I have a common problem while fetching the data from a web URL. As I run the following code I got the following warning and not data is retired. </p>
  
  <p><strong>The Warning:</strong></p>
  
  <blockquote>
    <p>Network request failed.</p>
  </blockquote>
  
  <p><strong>The Code:</strong></p>
  
  <pre><code>fetch('https://samples.openweathermap.org/data/2.5/forecast16?q=London&amp;appid=b6907d289e10d714a6e88b30761fae22', {
      method: 'POST',
      headers: {
        'Accept': 'application/json',
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        firstParam: 'yourValue',
        secondParam: 'yourOtherValue',
      })
    })
  </code></pre>
  
  <p>Also, I tried this one and I had the same problem:</p>
  
  <pre><code>  fetch('https://samples.openweathermap.org/data/2.5/forecast16?q=London&amp;appid=b6907d289e10d714a6e88b30761fae22')
         .then((response)=&gt;response.json())
         .then((resp)=&gt; data={resp})
         .catch( );
         console.log("data",this.resp);
    }
  </code></pre>
  
  <p>I should mention that I have this problem on Android. I searched a lot on this issue but I couldn't find a good solution. I also added the following code to the <code>AndroidManifest</code>, but the problem still exist. </p>
  
  <pre><code> &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  </code></pre>
  
  <p>Anther point that I should added is that the URL is not safe, since in Firefox it dose't show the data. </p>
  
  <p>Any Idea?</p>
