Type mismatch: cannot convert from org.apache.http.HttpResponse
提问by user1781367
I'm trying to update a MySQL data in Android by making HTTP Request but it gives me an error
我正在尝试通过发出 HTTP 请求来更新 Android 中的 MySQL 数据，但它给了我一个错误
"Type mismatch: cannot convert from org.apache.http.HttpResponse to com.google.api.client.http.HttpResponse"
“类型不匹配：无法从 org.apache.http.HttpResponse 转换为 com.google.api.client.http.HttpResponse”
on this line of code "httpClient.execute(httpPost)"
在这行代码“httpClient.execute(httpPost)”上
HttpResponse response = httpClient.execute(httpPost);
and it gives and option to quick fix by adding org.apache.http like
它提供了通过添加 org.apache.http 来快速修复的选项，例如
org.apache.http.HttpResponse response = httpClient.execute(httpPost);
Could someone tell me what I'm doing wrong here? Thank you so much!
有人能告诉我我在这里做错了什么吗？太感谢了！
protected String doInBackground(String... params) {
HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://---.com/---/approve_request.php");
List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();
nameValuePair.add(new BasicNameValuePair("status", "Approved"));
try {
httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
try {
org.apache.http.HttpResponse response = httpClient.execute(httpPost);
Log.d("Http Response:", response.toString());
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}

You have wrong import statement in your code.
您的代码中有错误的导入语句。
goto top of your class and look for
转到班级的顶部并寻找
import com.google.api.client.http.HttpResponse
import com.google.api.client.http.HttpResponse
replace it with
将其替换为
import org.apache.http.HttpResponse

You would be having
你会有
import com.google.api.client.http.HttpResponse;
in your imports list at the top of the source code.
在源代码顶部的导入列表中。
Please update that to
请将其更新为
import org.apache.http.HttpResponse;.
httpClient.execute(httpPost);is returning org.apache.http.HttpResponseobject and by having incorrect import type, you are trying to cast it to com.google.api.client.http.HttpResponse, which is cause the issue.
httpClient.execute(httpPost);正在返回org.apache.http.HttpResponse对象，并且由于导入类型不正确，您试图将其强制转换为com.google.api.client.http.HttpResponse，这是导致问题的原因。

org.apache.http.HttpResponseand com.google.api.client.http.HttpResponseare two completely separate and different Java classes. You cannot just simply take one and convert it to the other. If you are using Apache's HttpClient, then it will always return org.apache.http.HttpResponse, not the Android version. If you indeed want to use Apache's HttpClient, then I suggest you just stick to the Apache version instead of the Android version of HttpResponse and extract headers/content directly as needed.
org.apache.http.HttpResponse并且com.google.api.client.http.HttpResponse是两个完全独立且不同的 Java 类。您不能只是简单地将其转换为另一种。如果您使用的是 Apache 的HttpClient，那么它将始终返回org.apache.http.HttpResponse，而不是 Android 版本。如果您确实想使用 Apache 的 HttpClient，那么我建议您只使用 Apache 版本而不是 HttpResponse 的 Android 版本，并根据需要直接提取标头/内容。
