在服务器端,我使用Python烧瓶:
from flask import Flask, request
app = Flask(__name__)
@app.route("/upload", methods=["POST"])
def upload():
print request.files
print request.form
return "200 ok"
if __name__ == '__main__':
app.run(port=5000)
Java测试代码块:
public void test_Upload() throws Exception{
MediaType MEDIA_TYPE_PNG = MediaType.parse("image/png");
MediaType MEDIA_TYPE_XO = MediaType.parse("image/png");
RequestBody requestBody = new MultipartBuilder()
.type(MultipartBuilder.FORM)
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"title\""),
RequestBody.create(null, "Square Logo"))
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"image\""),
RequestBody.create(MEDIA_TYPE_PNG, new File("/Users/lollipop/Downloads/ic_launch.png")))
.addPart(
Headers.of("Content-Disposition", "form-data; name=\"google\""),
RequestBody.create(MEDIA_TYPE_XO, new File("/Users/lollipop/Downloads/google-logo.png")))
.build();
Request request = new Request.Builder()
.url("http://localhost:5000/upload")
.post(requestBody)
.build();
Response resp = httpClient.newCall(request).execute();
System.out.println(resp.body().string());
}
我正在进行测试。服务器端无法从request.forms
输出:
ImmutableMultiDict([])
ImmutableMultiDict([('image', u'5 ...many data ... fffd'), ('google', u'5i\u ...many data ... fffd'),('title', u'Square Logo')])
为什么我的文件上传到request.form
而不是request.files
。并且所有二进制文件数据都被解析为unicode字符串。
接下来,我在Python请求中进行测试。遵循代码:
resp = requests.post("http://localhost:5000/upload",
files={
"image": open("/Users/lollipop/Downloads/ic_launch.png", "rb"),
"title": open("/Users/lollipop/Downloads/ic_launch.png", "rb"),
"google": open("/Users/lollipop/Downloads/google-logo.png", "rb")
})
服务器端输出反转:
ImmutableMultiDict([('image', <FileStorage: u'ic_launch.png' (None)>), ('google', <FileStorage: u'google-logo.png' (None)>), ('title', <FileStorage: u'ic_launch.png' (None)>)])
ImmutableMultiDict([])
上传文件位于request.files
而非request.form
,这是我的预期结果。
因此。如何使用OkHttp将文件上传到烧瓶服务器,并使用request.files
进行检索。
request
是Flask requst。
from flask import request
requests是一个Python http客户端库。
