java - Android StringBody(String) 已弃用

Question

我正在尝试向我的 API 发送图像。但是在使用 MultipartEntity StringBody 时出现错误，因为不推荐使用 StringBody(String)。

我没有工作。我在 Android sending image to Server via MultipartEntity - setting Content-type? 做了一个 sample .

这是代码:

try {

    List<NameValuePair> params = new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("api_key", api_key));
    params.add(new BasicNameValuePair("access_token", access_token));

    API api = new API(mApiKey, mApiSecret);        


    HttpClient client = new DefaultHttpClient();
    HttpPost postMethod = new HttpPost("MY API URL");
    File file = new File(imagePath);
    MultipartEntity entity = new MultipartEntity();
    FileBody contentFile = new FileBody(file);

    StringBody api_key       = new StringBody(mApiKey);
    StringBody access_token  = new StringBody(access_token);

    entity.addPart("api_key", api_key);
    entity.addPart("hash", access_token);
    entity.addPart("image", contentFile);

    postMethod.setEntity(entity);
    client.execute(postMethod);



} catch (Exception e) {
    e.printStackTrace();
}

用于创建 StringBody 新实例的构造函数已弃用。

代替

new StringBody(mApiKey);

你应该使用一个 StringBody 构造函数，第二个参数是一个 ContentType 就像

new StringBody(mApiKey, ContentType.TEXT_PLAIN);
