相关疑难解决方法(0)

我使用XMLHttpRequest发送到服务器端创建的可恢复上传URL,将基于浏览器的可恢复上传到Google的云存储中.这在禁用Web安全性时完全正常,我在开发期间执行了此操作.

但现在在现实世界中,CORS一直在制造麻烦.我也尝试过与其他浏览器(没有成功),但坚持使用chrome进行进一步测试.

注意:fake.host条目/etc/HOSTS用于欺骗chrome以避免localhost限制.然而,我们的在线测试服务器的"真实"域也是如此.

使用普通的XMLHttpRequest调用启动请求:

var xhr = this.newXMLHttpRequest();
xhr.open('PUT', url, true);

xhr.setRequestHeader('Content-Type', this.currentInputFile.type);
xhr.setRequestHeader('Content-Range', 'bytes ' + startByte + '-' + (this.currentInputFile.size - 1) + '/' + this.currentInputFile.size);

xhr.onload = function(e) {
   ...
};

...

if (startByte > 0) {
    xhr.send(this.currentInputFile.slice(startByte));
} else {
    xhr.send(this.currentInputFile);
}

然后浏览器成功启动预检请求:
