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 时出现错误，因为 StringBody(String) 已被弃用。

我不工作。我是Android sending image to Server via MultipartEntity - setting Content-type?的一个样本。

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();
}

Answer 1

用于创建StringBody 的新实例的构造函数已弃用。

代替

new StringBody(mApiKey);

您应该使用StringBody 构造函数和第二个参数，即ContentType 类似

new StringBody(mApiKey, ContentType.TEXT_PLAIN);

Answer 2

字符串体：

 entity.addPart("api_key", new StringBody(mApiKey,ContentType.TEXT_PLAIN));

多部分实体：

检查：The type MultipartEntity is deprecated
