Question

第一个解决方案比我尝试过我使用方法beginQuoteFileUnquoteUpload1它创建了一个很好的边界和良好的Content-Type但是当我收到文件时。该文件已损坏：（

var formData = new FormData(); 
formData.append('file', document.getElementById('file').files[0], document.getElementById('file').files[0].name);

function beginQuoteFileUnquoteUpload1(data)
{
    // Define a boundary, I stole this from IE but you can use any string AFAIK
    var boundary = "---------------------------7da24f2e50046";
    var xhr = null;
    if (window.XMLHttpRequest || window.ActiveXObject) {
	if (window.ActiveXObject) {
		try {
			xhr = new ActiveXObject("Msxml2.XMLHTTP");
		} catch(e) {
			xhr = new ActiveXObject("Microsoft.XMLHTTP");
		}
	}else{
		xhr = new XMLHttpRequest(); 
	}
    }else{
	alert("Votre navigateur ne supporte pas l'objet XMLHTTPRequest...");
	return;
    }
    var body = '--' + boundary + '\r\n'
             + 'Content-Disposition: form-data; name="file";'
             + 'filename="'+document.getElementById('file').files[0].name+'"\r\n'
             + 'Content-type: application/pdf\r\n\r\n'
             + data + '\r\n'
             + '--'boundary + '--';

    var url ="https://gedcreditor.mycloud.by/Myproject/ws/rest/sendemail/";
    url+=document.getElementById('file').files[0].name;
    url+="/a/a/a";	
    xhr.open("POST", url, true);
    xhr.setRequestHeader(
        "Content-type", "multipart/form-data; boundary="+boundary);
    xhr.setRequestHeader('Authorization','Bearer ' + JWTtoken);//Our test server does not accept JWt, once we use AXA server, we will test the JWT
    xhr.setRequestHeader('ApiKey','lRABmnmS_H1Ej9yaowxqwEsuBbkxkgrzx-C1Jji_HfnJyKywR8NeuSkIJbhutfNg');	
    xhr.onreadystatechange = function ()
    {
        if (xhr.readyState == 4 && xhr.status == 200)
            alert("File uploaded!");
    }
    xhr.send(body);
}

beginQuoteFileUnquoteUpload1(formData);

*********结果**************** ******************

----------------------------- 7da24f2e50046 -----＆gt;好内容处理：表格数据; NAME = “文件”;文件名= “servlet.pdf” 内容类型：application / pdf

--------------------------- 7da24f2e50046-- 内容类型multipart / form-data; boundary = --------------------------- 7da24f2e50046 ----＆gt;行

第二个解决方案确实有效，因为防火墙阻止了我，因为我在方法和结果下面没有相同的边界。

var formData = new FormData(); 
formData.append('file', document.getElementById('file').files[0], document.getElementById('file').files[0].name);
function beginQuoteFileUnquoteUpload(data)
{
    // Define a boundary, I stole this from IE but you can use any string AFAIK
    var boundary = "---------------------------7da24f2e50046";
    var xhr = null;
    if (window.XMLHttpRequest || window.ActiveXObject) {
	if (window.ActiveXObject) {
		try {
			xhr = new ActiveXObject("Msxml2.XMLHTTP");
		} catch(e) {
			xhr = new ActiveXObject("Microsoft.XMLHTTP");
		}
	}else{
		xhr = new XMLHttpRequest(); 
	}
    }else{
	alert("Votre navigateur ne supporte pas l'objet XMLHTTPRequest...");
	return;
    }
    var url ="https://gedcreditor.mycloud.by/GEDCREDITOR_01_06/ws/rest/sendemail/";
    url+=document.getElementById('file').files[0].name;
    url+="/a/a/a";	
    xhr.open("POST", url, true);
    xhr.setRequestHeader(
        "Content-type", "multipart/form-data; boundary="+boundary);
    //xhr.setRequestHeader('Authorization','Bearer ' + JWTtoken);//Our test server does not accept JWt, once we use AXA server, we will test the JWT
   // xhr.setRequestHeader('ApiKey','lRABmnmS_H1Ej9yaowxqwEsuBbkxkgrzx-C1Jji_HfnJyKywR8NeuSkIJbhutfNg');	
    xhr.onreadystatechange = function ()
    {
        if (xhr.readyState == 4 && xhr.status == 200)
            alert("File uploaded!");
    }
    xhr.send(data);
}

beginQuoteFileUnquoteUpload(formData);

Answer 1

第二种方法是正确的方法，除了您没有设置内容类型标题。使用FormData对象发出请求时，它会自动正确设置。

IE11：IE11中的Content-Type = false它不起作用
