Apache HttpClient制作多部分表单帖子
Apache HttpClient制作多部分表单帖子
提问于 2010-02-21 11:35:39
我对HttpClient非常陌生，而且我发现缺少(或者明显不正确的)文档非常令人沮丧。我正在尝试使用Apache Http客户端实现以下帖子(如下所示)，但不知道如何实际执行。我将埋头于下周的文档工作，但也许更有经验的HttpClient程序员可以更快地给我一个答案。

从HttpMime library使用MultipartEntityBuilder执行所需的请求。
在我的项目中，我是这样做的：
HttpEntity entity = MultipartEntityBuilder
.create()
.addTextBody("number", "5555555555")
.addTextBody("clip", "rickroll")
.addBinaryBody("upload_file", new File(filePath), ContentType.APPLICATION_OCTET_STREAM, "filename")
.addTextBody("tos", "agree")
.build();
HttpPost httpPost = new HttpPost("http://some-web-site");
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost);
HttpEntity result = response.getEntity();希望这能有所帮助。
(更新了这篇文章，使用@mtomy代码作为示例，使用MultipartEntityBuilder代替废弃的MultipartEntity )

如果使用org.apache.commons.httpclient.HttpClient包，可能会对你有所帮助！
HttpConnectionManager httpConnectionManager = new MultiThreadedHttpConnectionManager();
//here should set HttpConnectionManagerParams but not important for you
HttpClient httpClient = new HttpClient(httpConnectionManager);
PostMethod postMethod = new PostMethod("http://localhost/media");
FilePart filePart = new FilePart("file", new File(filepath));
StringPart typePart = new StringPart("type", fileContent.getType(), "utf-8");
StringPart fileNamePart = new StringPart("fileName", fileContent.getFileName(), "utf-8");
StringPart timestampPart = new StringPart("timestamp", ""+fileContent.getTimestamp(),"utf-8");
Part[] parts = { typePart, fileNamePart, timestampPart, filePart };
MultipartRequestEntity multipartRequestEntity = new MultipartRequestEntity(parts, postMethod.getParams());
postMethod.setRequestEntity(multipartRequestEntity);
httpClient.executeMethod(postMethod);
String responseStr = postMethod.getResponseBodyAsString();页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
