Android StringBody(String)已弃用

Question

我正在尝试将图像发送到我的API.但是在使用MultipartEntity StringBody时我得到错误,因为不推荐使用StringBody(String).

我不工作.我是Android的一个示例,通过MultipartEntity将图像发送到服务器 - 设置内容类型？.

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();
}

不建议使用用于创建新实例的构造函数StringBody.

代替

new StringBody(mApiKey);

你应该使用一个StringBody构造器是第二个参数ContentType一样

new StringBody(mApiKey, ContentType.TEXT_PLAIN);
