用的httpClient，相关代码如下 String result=null; //文件名 String fileName = file.getName(); MultipartEntityBuilder mBuilder = MultipartEntityBuilder.create(); mBuilder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE); mBuilder.addBinaryBody("media", file, ContentType.DEFAULT_BINARY, fileName); HttpEntity he = mBuilder.build(); SSLContext context = getTrustAllSSLContext(); SSLConnectionSocketFactory factory = new SSLConnectionSocketFactory(context); CloseableHttpClient client = HttpClients.custom().setSSLSocketFactory(factory).build(); try { HttpPost post = wxPost(url); post.setEntity(he); CloseableHttpResponse reponse = client.execute(post); try { HttpEntity entity = reponse.getEntity(); result = EntityUtils.toString(entity); EntityUtils.consume(entity); } finally { reponse.close(); } } finally { client.close(); } return result; 返回的是{"errcode":40005,"errmsg":"invalid file type hint: [iIdHwA05760016] rid: 5fb4ae20-29f4fcd2-69b1e7b1"}
