Question

我正在尝试将日文字符发送到我的API服务器，但发送的字符出现乱码并变为????。所以我使用以下命令将编码设置为实体：

    StringEntity stringEntity = new StringEntity(message, "UTF-8");

但输出变为org.apache.http.entity.StringEntity@4316f850。我想知道是否将stringEntity转换为字符串会导致这种情况，因为我想将其作为String发送到我的服务器中。

以下是我如何使用它：

public static String postSendMessage(String path, String message) throws Exception {
    DefaultHttpClient httpClient = new DefaultHttpClient();
    HttpConnectionParams.setConnectionTimeout(httpClient.getParams(), 10000); // Timeout limit
    HttpPost httpPost = new HttpPost(SystemInfo.getApiUrl() + path);
    List<NameValuePair> value = new ArrayList<NameValuePair>();

    StringEntity stringEntity = new StringEntity(message, "UTF-8");
    value.add(new BasicNameValuePair("message", stringEntity.toString())); //Here's where I converted the stringEntity to string

    UrlEncodedFormEntity entity = new UrlEncodedFormEntity(value);
    httpPost.setEntity(entity);
    HttpResponse httpResponse = httpClient.execute(httpPost);

    HttpEntity httpEntity = httpResponse.getEntity();
    InputStream is = httpEntity.getContent();

    String result = convertStreamToString(is);
    return result;
}

我哪里可能出错？

您无需使用StringEntity。

List<NameValuePair> value = new ArrayList<NameValuePair>();
value.add(new BasicNameValuePair("message", message));

相反，你必须传递第二个参数来初始化`UrlEncodedFormEntity。

UrlEncodedFormEntity entity = new UrlEncodedFormEntity(value, "UTF-8");
