web获取打印机列表

let printerName = "";
fetch("http://localhost:8000/getPrintList", {
	method: "GET",
headers: { "Content-Type": "application/json" },
})
.then((response) => response.json())
.then((data) => {
 console.log("Response:", data.data);
 printerName = data.data.filter((e) => e.isDefault === true)[0].name;
});

打印(arrayBuffer )

fetch方法

fetch(`http://localhost:8000/print?printerName=${printerName}`, {
	method: "POST",
headers: {
 "Content-Type": "application/pdf",
},
body: arrayBuffer,
})
.then((response) => response.text())
.then((data) => {
 	alert(data);
})
.catch((error) => {
	console.error("发送失败:", error);
	alert("发送失败");
});

axios方法

const queryString = new URLSearchParams({ printerName: '', duplex:false, paperSize:'A4'}).toString()
axios
.post(`http://localhost:8000/print?${queryString}`, arrayBuffer, {
 headers: {
 'Content-Type': 'application/pdf'
 }
})
.then((response) => {
 
})
.catch((error) => {
 console.error('请求失败:', error)
})

Blob 转 ArrayBuffe

// 创建一个 FileReader 对象来将 Blob 转换为 ArrayBuffer
 const reader = new FileReader()
 reader.onloadend = function () {
 pdfArrayBuffer = reader.result
 }
 reader.readAsArrayBuffer(Blob)

打印(url)

fetch方法

const url = 'https://pdf-lib.js.org/assets/with_update_sections.pdf'
fetch(url).then(response=>{
 return response.arrayBuffer();
}).then(arrayBuffer=>{
 console.log("PDF ArrayBuffer:", arrayBuffer);
})

axios方法

axios.get(url, { responseType: 'arraybuffer' }).then((response) => {
 const arrayBuffer = response.data
})
