httpclient upload file
用httpclient upload上传文件时,代码如下:
HttpPost httpPost = new HttpPost(uploadImg);
httpPost.addHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8");
httpPost.addHeader("Accept-Encoding", "gzip, deflate");
httpPost.addHeader("Accept-Language", "zh-CN,zh;q=0.8,en;q=0.6");
httpPost.addHeader("Cache-Control", "max-age=0");
httpPost.addHeader("Connection", "keep-alive");
httpPost.addHeader("Content-Type", "multipart/form-data;"); File file = new File("/Users/xxx/Desktop/新建文件夹/1.jpg"); byte[] fileBytes = readInputStream(new FileInputStream(file));
byte[] imgBytes = Base64.encodeBase64(fileBytes);
String img = new String(imgBytes);
img = img.replace("\n", ""); MultipartEntityBuilder builder = MultipartEntityBuilder.create();
builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE); builder.addBinaryBody("file", file, ContentType.create("image/jpeg"), file.getName());
HttpEntity entity = builder.build();
httpPost.setEntity(entity); HttpResponse httpResponse = HttpClientBuilder.create().build().execute(httpPost);
String responseStr = EntityUtils.toString(httpResponse.getEntity(), "UTF-8");
System.err.println(responseStr);
一直提示如下异常:

原因在于设定了contentType的值。当为boundary设定了contentType后,server不知道boundary如何处理。
因此,删掉contentType的设定即可。
