html ajax 二进制,javascript – 使用jQuery AJAX使用二进制数据发送FormData

我想通过使用jQuery AJAX发送FormData,如：

var uploadFormData = new FormData();

uploadFormData.append("name","value");

$.ajax({

url : "(URL_target)",

type : "POST",

data : uploadFormData,

cache : false,

contentType : false,

processData : false,

success : function(r) {

alert("Success!");

}

});

但我也希望使用jQuery AJAX发送二进制数据,如：

var data = (...);

$.ajax({

url: "(URL_target)",

type: "POST",

data : data,

cache : false,

contentType: "application/octet-stream",

processData: false,

success : function(r) {

alert("Success!");

}

});

如何将它们组合成一个数据并发送出去？

解决方法:

您可以将二进制数据作为Blob,File,ArrayBuffer对象或数据URI附加到FormData对象

var uploadFormData = new FormData();

var data = (...);

uploadFormData.append("name","value");

uploadFormData.append("data", new Blob([data], {type:"application/octet-stream"}));

$.ajax({

url : "(URL_target)",

type : "POST",

data : uploadFormData,

cache : false,

contentType : false,

processData : false,

success : function(r) {

alert("Success!");

}

});
