下午好,
一般情况下,我需要通过JSOUP以响应multipart / form-data的形式向站点发送数据
举一个例子,采用一个简单的形式来sgeniriruet您的查询。
< form action =«localhost:8000»method =«post»enctype =«multipart / form-data»
< input type =«text»name =«text»value =«text default»
< input type =«file»name =«file1»
< input type =«file»name =«file2»
提交< /按钮
< /形式
浏览器发布回复:

我尝试创建类似的请求,但没有找到正确的方法,以便服务器收到请求。
我的代码:
Map<String, String> responseMap= new HashMap<String, String>();
String key1 = "------WebKitFormBoundary9A3GpeDAwfa0TBDK\r\n" +
"Content-Disposition: form-data; name=\"text\"\r\n\r\n";
String value1 = "text default";
headersMap.put(key1, value1);
String key2 = "\r\n------WebKitFormBoundary9A3GpeDAwfa0TBDK\r\n" +
"Content-Disposition: form-data; name=\"doc_sma_ref_file\"; filename=\"\"" +
"\r\nContent-Type: application/octet-stream\r\n\r\n";
String value2 = "";
headersMap.put(key2, value2);
String key3 = "\r\n------WebKitFormBoundary9A3GpeDAwfa0TBDK\r\n" +
"Content-Disposition: form-data; name=\"doc_val_ref_file\"; filename=\"\"" +
"\r\nContent-Type: application/octet-stream\r\n\r\n";
String value3 = "";
headersMap.put(key3, value3);
String key4 = "\r\n------WebKitFormBoundary9A3GpeDAwfa0TBDK--";
String value4 = "";
headersMap.put(key4, value4);
Connection.Response resBGT = Jsoup.connect(URL)
.header("Content-Type", "multipart/form-data; boundary=----WebKitFormBoundary9A3GpeDAwfa0TBDK")
.userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/42.0.2311.90 Safari/537.36")
.followRedirects(true)
.data(responseMap)
.cookies(cookies)
.ignoreHttpErrors(true)
.timeout(15000)
.method(Connection.Method.POST)
.execute();
也许有人有这方面的经验。如果你请发送正确的路径。 也许有机会看到生成jsoup的请求
感谢您的帮助。

您可以使用Connection.data
的第三个参数:
File file1 = new File("C:/dir/file1.txt");
File file2 = new File("C:/dir/file2.txt");
FileInputStream fs1 = new FileInputStream(file1);
FileInputStream fs2 = new FileInputStream(file2);
Connection.Response response = Jsoup.connect("http://www.example.com")
.data("text", "value")
.data("file1", "filename", fs1)
.data("file2", "filename", fs2)
.userAgent("Mozilla")
.method(Method.POST)
.execute();
//Handle your response...

在JSoup 1.12.1之前,除非文件被包含在表单发布中,否则无法自动发送表单边界。
从1.12.1开始,当Content-Type
标头设置为"multipart/form-data"
时,Jsoup可以生成表单边界。不再需要在表单数据中添加文件以自动生成mime边界。
Document doc = Jsoup.connect(echoUrl)
.header("Content-Type", "multipart/form-data")
.userAgent(browserUa)
.data("uname", "Jsoup", "uname", "Jonathan", "百", "度一下")
.post();
您可以在上面的代码中看到,没有使用任何文件,但是JSoup会动态处理表单边界,因为内容类型为multipart/form-data
。
