我试图提交一个包含有vibe.d图像的多部分表单
我的代码如下所示:
auto f = File("image.jpg");
auto data = new char[f.size];
f.rawRead(data);
string boundary = randomUUID.toString.toUpper();
string h = "--Boundary-" ~ boundary ~ "\r\n";
h ~= `Content-Disposition: form-data; name="type"` ~ "\r\n\r\n";
h ~= "photo\r\n";
h ~= "--Boundary-" ~ boundary ~ "\r\n";
h ~= `Content-Disposition: form-data; name="photo"; filename="558704D0-2855-4689-996C-F556BE4A3872.jpg"` ~ "\r\n";
h ~= "Content-Type: image/jpeg\r\n\r\n";
h ~= data ~ "\r\n";
h ~= "--Boundary-" ~ boundary ~ "\r\n";
h ~= `Content-Disposition: form-data; name="photo_ids"` ~ "\r\n\r\n";
h ~= `["55227F15-36D2-4A04-A4D9-FB23C00627D1"]` ~ "\r\n";
h ~= "--Boundary-" ~ boundary ~ "\r\n";
auto response = requestHTTP("https://httpbin.org/anything", (scope req) {
req.method = HTTPMethod.POST;
req.headers["content-type"] = "multipart/form-data; boundary=Boundary-" ~ boundary;
req.headers["content-length"] = to!string(h.length);
req.bodyWriter.write(h);
}).bodyReader.readAllUTF8();
logInfo(response);但是httpbin告诉我我什么也没发:
[main(----) INF] {
[main(----) INF] "args": {},
[main(----) INF] "data": "",
[main(----) INF] "files": {},
[main(----) INF] "form": {},
[main(----) INF] "headers": {
[main(----) INF] "Accept-Encoding": "gzip, deflate",
[main(----) INF] "Content-Length": "58038",
[main(----) INF] "Content-Type": "multipart/form-data; boundary=Boundary-76CCC942-83EB-4339-BB6B-2C7D5BF027B6",
[main(----) INF] "Host": "httpbin.org",
[main(----) INF] "User-Agent": "vibe.d/1.7.0 (HTTPClient, +http://vibed.org/)"
[main(----) INF] },
[main(----) INF] "json": null,
[main(----) INF] "method": "POST",
[main(----) INF] "origin": "",
[main(----) INF] "url": "https://httpbin.org/anything"
[main(----) INF] }我不知道我做错了什么。会很感激你的帮助

您的多部分数据格式错误。对于最后一个边界,您必须附加一个"--“字符串来表示结束。所以,而不是上一次
h ~= "--Boundary-" ~ boundary ~ "\r\n";它必须是
h ~= "--Boundary-" ~ boundary ~ "--\r\n";`然后它就能工作了。
请参阅https://www.freesoft.org/CIE/RFC/1521/16.htm
最终,这应该作为vibe.d中的API来支持,并且有两个打开的PRs来实现这个功能,但是现在您必须像以前一样对它进行处理。

现在Vibe.d的当前版本大大简化了它。
请确保在表单的封装类型中声明“多部分/表单-数据”:
form.form-grid(method="post", action="new_employee", enctype="multipart/form-data")然后,该形式的字段应该包含一个类型为“file”的输入字段,如下所示:
input(type="file", name="picture")在web框架类的postNewEmployee()方法中,通过request.files获取文件:
auto pic = "picture" in request.files;下面是正在传递一个Employee结构的示例postNewEmployee()方法:
void postNewEmployee(string _authUser, Employee e)
{
import std.file;
import std.path;
import std.algorithm;
string photopath = "No photo submitted";
auto pic = "picture" in request.files;
if(pic !is null)
{
string ext = extension(pic.filename.name);
string[] exts = [".jpg", ".jpeg", ".png", ".gif"];
if(canFind(exts, ext))
{
photopath = "uploads/photos/" ~ e.fname ~ "_" ~ e.lname ~ ext;
string dir = "./public/uploads/photos/";
mkdirRecurse(dir);
string fullpath = dir ~ e.fname ~ "_" ~ e.lname ~ ext;
try moveFile(pic.tempPath, NativePath(fullpath));
catch (Exception ex) copyFile(pic.tempPath, NativePath(fullpath));
}
}
e.photo = photopath;
if(e.phone.length == 0) e.phone = "(123) 456 7890";
if(e.paygd.length == 0) e.paygd = "none yet";
if(e.postcode.length == 0) e.postcode = "A1A 1A1";
e.pword = createDigestPassword(realm, e.email, e.pword);
empModel.addEmployee(e);
redirect("list_employees");
}当我再次尝试学习Vibe.d时,我再次意识到缺乏教程,所以我自己写了一个教程,而作为一个学习者,一切都是新鲜的:
