我正在尝试使用Google Drive file Picker (基于这个示例https://gist.github.com/Daniel15/5994054)下载一个文件。文件选取器在下载文件时工作得很好。它会遇到400错误请求(lockedDomainCreationFailure)错误。
代码如下:
function downloadFile(file, callback) {
if (file.downloadUrl) {
var accessToken = gapi.auth.getToken().access_token;
var xhr = new XMLHttpRequest();
xhr.open('GET', file.downloadUrl);
xhr.setRequestHeader('Authorization', 'Bearer ' + accessToken);
xhr.onload = function() {
callback(xhr.responseText);
};
xhr.onerror = function() {
callback(null);
};
xhr.send();
} else {
callback(null);
}
}以下是错误消息:
{
"error": {
"errors": [
{
"domain": "global",
"reason": "lockedDomainCreationFailure",
"message": "The OAuth token was received in the query string, which this API forbids for response formats other than JSON or XML. If possible, try sending the OAuth token in the Authorization header instead."
}
],
"code": 400,
"message": "The OAuth token was received in the query string, which this API forbids for response formats other than JSON or XML. If possible, try sending the OAuth token in the Authorization header instead."
}
}它告诉我们to OAuth令牌是在查询字符串中给定的,我认为这不是真的。下面是请求:
GET /drive/v2/files/{file-id}?key={app-key}&alt=media&source=downloadUrl HTTP/3

TE: Trailers由于我使用的是to Google API提供的下载url,而授权是在请求标头中给出的,所以我不知道为什么会遇到这个错误。
我很欣赏你的想法。

解决方案是将主机content.googleapis.com (从Google API提供的下载url )更改为www.googleapis.com。感谢ziganotschka的提示!
因此,正确的下载url是https://www.googleapis.com/drive/v2/files/{file-id}?key={app-key}&alt=media&source=downloadUrl。它必须包含"alt“和"source”查询参数,否则您只能获取文件元数据,而不能获取其内容。不需要更改"Accept“头。
