如何在node.js中使用boudary分隔multipart / form-data

Question

Contents of the message received form the HttpPost

我在Node.js上运行Azure函数

到达的消息具有指定边界的内容类型。

'content-type': 'multipart/form-data; 
boundary=------------------------8bb0bdeb26804014' },

如何获取RawRequest中找到的对象？

--------------------------8bb0bdeb26804014\r\nContent-Disposition: form data; name="rawRequest"\r\n\r\n

{"slug":"submit\\/80705882093865\\/",
"q1_nombres":"first":"textbox_sample0",
"last":"textbox_sample1"},
"q3_email":"john@example.com",
"preview":"true"}\r\n

EDIT1：

到目前为止我这样做：

var parts = req.headers['content-type'].split('boundary=');
var boundary = parts[1];
context.log("Boundary: "+boundary);
var splitBody = req.body.split( boundary );
context.log("RawRequest: "+splitBody[8]);

但我仍然需要解决这个问题：

Content-Disposition: form-data; name="rawRequest"

{"slug":"submit\/80705882093865\/",
"q1_nombres":{"first":"textbox_sample0",
"last":"textbox_sample1"},
"q3_email":"john@example.com",
"preview":"true"} --

如果我开始进一步操纵字符串，它似乎很容易破裂。

尝试substring()方法来实现这个目标怎么样？

var indexStart = splitBody.indexOf('{');
var indexEnd = splitBody.lastIndexOf('}') + 1;
var rawRequest = str.substring(indexStart, indexEnd);
console.log(rawRequest);
