制作一个包含 MultipartEntity 的 HttpRequest
我一直在尝试弄清楚如何使用其中的多部分实体发出 http 请求，这让我感到沮丧。多部分有一个自定义边界，但我似乎无法设置它。我的下面的代码会生成一条响应消息，指出我的消息不包含多个部分。
HttpPut addDoc = new HttpPut(url);
addDoc.addHeader("Content-Type", "multipart/related; boundary=\"END_OF_PART\"");
String bodyString = "Test for multipart update";
String titleString = "Title Test for multipart update";
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
StringBody title = new StringBody(titleString, "application/atom+xml",Charset.forName("UTF-8"));
StringBody body = new StringBody(bodyString, "text/plain",Charset.forName("UTF-8"));
entity.addPart("title", title);
entity.addPart("body", body);
addDoc.setEntity(entity);
I've been frustrated at trying to figure out how to make an http request with a multipart entity in it. The multipart has a custom boundary but I can't seem to be able to set it. My code below results in a response message of saying that my message does not contain multiple parts.
HttpPut addDoc = new HttpPut(url);
addDoc.addHeader("Content-Type", "multipart/related; boundary=\"END_OF_PART\"");
String bodyString = "Test for multipart update";
String titleString = "Title Test for multipart update";
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
StringBody title = new StringBody(titleString, "application/atom+xml",Charset.forName("UTF-8"));
StringBody body = new StringBody(bodyString, "text/plain",Charset.forName("UTF-8"));
entity.addPart("title", title);
entity.addPart("body", body);
addDoc.setEntity(entity);

您可以尝试从代码中删除 addHeader 部分并将构造函数更改为
you can try to remove addHeader part from your code and change your constructor to
首先，您可以尝试使用：
这是初始化它的正确方法，然后：
至于边界，您的问题不清楚是否需要读取自定义边界或设置它，无论如何，自定义边界设置如下方式;
First of all you could try using:
which is the correct way to initialize it, and then:
as for the boundary your question is not clear whether you need to read a custom boundary or set it, anyway the custom boundary is set in the following way;
