示例1: writeMultipart
private void writeMultipart(MultiValueMap<String, Object> parts, HttpOutputMessage outputMessage)
throws IOException {
byte[] boundary = generateMultipartBoundary();
Map<String, String> parameters = Collections.singletonMap("boundary", new String(boundary, "US-ASCII"));
MediaType contentType = new MediaType(MediaType.MULTIPART_FORM_DATA, parameters);
outputMessage.getHeaders().setContentType(contentType);
writeParts(outputMessage.getBody(), parts, boundary);
writeEnd(boundary, outputMessage.getBody());
}
示例2: determineContentType
/**
* Tries to determine the content/media type of this HTTP request iff the HTTP "Content-Type"
* header was not explicitly set by the user, otherwise the user provided value is used. If the
* "Content-Type" HTTP header value is null, then the content/media/payload of this HTTP request
* is inspected to determine the content type.
* <p/>
* The simplest evaluation sets the content type to "application/x-www-form-urlencoded" if this is
* a POST or PUT HTTP request, unless any request parameter value is determined to have multiple
* parts, the the content type will be "multipart/form-data".
* <p/>
*
* @param defaultContentType the default content/media type to use when the content type cannot be
* determined from this HTTP request.
* @return a MediaType for the value of the HTTP Content-Type header as determined from this HTTP
* request.
* @see #getHeaders()
* @see org.springframework.http.HttpHeaders#getContentType()
* @see org.springframework.http.MediaType
