不推荐使用 MultipartEntity 类型 [英] The type MultipartEntity is deprecated

问题描述

文档说 org.apache.http.entity.mime.MultipartEntity 类已弃用.有人可以给我建议一个替代方案吗?

我在我的代码中使用这个:

entity.addPart("params", new StringBody("{\"auth\":{\"key\":\""+ authKey + "\"},\"template_id\":\"" + templateId + "\"}"));entity.addPart("my_file", new FileBody(image));httppost.setEntity(实体);

解决方案

如果你仔细阅读文档，你会注意到你应该使用 MultipartEntityBuilder 作为替代.

例如:

MultipartEntityBuilder builder = MultipartEntityBuilder.create();/* 设置 HttpMultipartMode 的示例 */builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);/* 添加图像部分的示例 */FileBody fileBody = new FileBody(new File(image));//图像应该是一个字符串builder.addPart("my_file", fileBody);//等等

请注意，FileBody 类，通过它可以提供mimeType、内容类型等>

完成将构建指令传递给构建器后，您可以获得构建的HttpEntity 通过调用 MultipartEntityBuilder#build() 方法:

HttpEntity entity = builder.build();

The documentation says the org.apache.http.entity.mime.MultipartEntity class is deprecated. Could anybody please suggest me an alternative ?

I am using this in my code like this:

entity.addPart("params", new StringBody("{\"auth\":{\"key\":\""
            + authKey + "\"},\"template_id\":\"" + templateId + "\"}"));
entity.addPart("my_file", new FileBody(image));
httppost.setEntity(entity);

解决方案

If you read the docs carefully, you'll notice that you should use MultipartEntityBuilder as an alternative.

For example:

MultipartEntityBuilder builder = MultipartEntityBuilder.create();        

/* example for setting a HttpMultipartMode */
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

/* example for adding an image part */
FileBody fileBody = new FileBody(new File(image)); //image should be a String
builder.addPart("my_file", fileBody); 
//and so on

Note that there are several constructors for the FileBody class, by which you can provide mimeType, content type, etc.

After you're done with passing build instructions to the builder, you can get the built HttpEntity by invoking the MultipartEntityBuilder#build() method:

HttpEntity entity = builder.build();
