NodeJS请求如何发送多部分/表单数据POST请求

问题描述：

我正在尝试将POST请求发送到带有请求中图像的API.我正在使用请求模块执行此操作，但是我尝试执行的所有操作均不起作用.我当前的代码:

I'm trying to send a POST request to an API with an image in the request. I'm doing this with the request module but everything I try it isn't working. My current code:

const options = {
    method: "POST",
    url: "https://api.LINK.com/file",
    port: 443,
    headers: {
        "Authorization": "Basic " + auth,
        "Content-Type": "multipart/form-data"
    },
    form : {
        "image" : fs.readFileSync("./images/scr1.png")
    }
};

request(options, function (err, res, body) {
    if(err) console.log(err);
    console.log(body);
});

但是由于某些原因请求使用Content-Type: application/x-www-form-urlencoded ...如何解决此问题?

But request uses Content-Type: application/x-www-form-urlencoded for some reason... How can I fix this?

答

如文档表单multipart/form-data请求正在使用form-data库.因此，您需要提供formData选项而不是form选项.

As explained in documentation form multipart/form-data request is using form-data library. So you need to supply formData option instead of form option.

const options = {
    method: "POST",
    url: "https://api.LINK.com/file",
    port: 443,
    headers: {
        "Authorization": "Basic " + auth,
        "Content-Type": "multipart/form-data"
    },
    formData : {
        "image" : fs.createReadStream("./images/scr1.png")
    }
};

request(options, function (err, res, body) {
    if(err) console.log(err);
    console.log(body);
});
