Request Payload参数(字典，json，列表，字符串，以及DWR框架的参数)

1.正常的Json数据

常规提交POST数据当然了，这样写和下面的提交的原理是一样的：

2.Request Payload是正常json数据

什么是Request Payload ？也是Json数据的一种。但是也稍有不同，因为Request Payload 也可以是列表。具体的不涉及前后端的话知道这点就够了。

json数据那么发请求的话在这里插入图片描述如果发送失败的话，记得添加method=“POST” 这样就OK了

3.Request Payload 是一个列表情形一注意：这种方式的话是一定需要设置请求头的。

在这里插入图片描述这种情况我也是第一次见，且使用Scrapy框架时利用自带的FormReuqest 是无法完成要求的

转而利用requests模块，直接将内容转换为字符串提交，如图

在这里插入图片描述这样就请求过来的。但是是直接调用的requests模块。

情形二：列表中有中文字在这里插入图片描述需要先将中文字编译成UTF-8格式

print("昆明市".encode('utf-8')) #注意请求头的第一个参数一定要有 headers = { "ajax-method": "AjaxMethodFactory", "user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36" } data = '["TrueLore.Web.WebUI.WebAjaxService","GetPageZBGGByCCGC",[0,15,"\xe6\x98\x86\xe6\x98\x8e\xe5\xb8\x82","11,12,13,14,15,16,17,18,19,20","1","0","JSGC",1,"","","BDMCGGBT",""],null,null]1574150259770' proxies = random.choice([ {"HTTP": "http://代理"}, ]) res = requests.post("https://www.kmggzy.com/TrueLoreAjax/TrueLore.Web.WebUI.AjaxHelper,TrueLore.Web.WebUI.ashx",data = data,headers=headers,verify=False,proxies=proxies)

到此成功请求

4.Java DWR异步框架参数提交

DWR框架的参数列表提交方式: 在这里插入图片描述将参数提交的POST请求即可将数据获取过来，注意不要讲提交参数的格式改变了

5.参数及请求头 {"token":"","pn":20,"rn":10,"sdt":"","edt":"","wd":"","inc_wd":"","exc_wd":"","fields":"title","cnum":"001;002;003;004;005;006;007;008;009;010","sort":"{\"showdate\":\"0\"}","ssort":"title","cl":200,"terminal":"","condition":[{"fieldName":"categorynum","isLike":true,"likeType":2,"equal":"001001"}],"time":null,"highlights":"title","statistics":null,"unionCondition":null,"accuracy":"100","noParticiple":"0","searchRange":null,"isBusiness":1}: Content-Type: application/x-www-form-urlencoded; charset=UTF-8

解决方法: 将参数构成dict

form_data = { "token": "", "pn": str(page*10), "rn": "10", "sdt": "", "edt": "", "wd": "", "inc_wd": "", "exc_wd": "", "fields": "title", "cnum": "001;002;003;004;005;006;007;008;009;010", "sort": "{\"showdate\":\"0\"}", "ssort": "title", "cl": "200", "terminal": "", "condition": '[{"fieldName": "categorynum", "isLike": "true", "likeType": "2", "equal": "001001"}]', "time": 'null', "highlights": "title", "statistics": 'null', "unionCondition": 'null', "accuracy": "100", "noParticiple": "0", "searchRange": 'null', "isBusiness": "1" }

json.dumps提交，成功获取数据 2022-02-16,最新版本：将null替换成None,true替换成True,false替换成False

{"token": "", "pn": 0, "rn": 10, "sdt": "", "edt": "", "wd": "", "inc_wd": "", "exc_wd": "", "fields": "titlenew", "cnum": "005", "sort": "{\"webdate\":0}", "ssort": "title", "cl": 200, "terminal": "", "condition": [{"fieldName": "categorynum", "equal": "002001003", "notEqual": None, "equalList": None, "notEqualList": None, "isLike": True, "likeType": 2}], "time": None, "highlights": "", "statistics": None, "unionCondition": None, "accuracy": "", "noParticiple": "0", "searchRange": None, "isBusiness": "1"}

在这里插入图片描述

6.参数及请求头

在这里插入图片描述

{"noticeTitle":"","effectTime":"","failureTime":"","noticeType":"null","purchaseNoticeType":"2","resultsNoticeType":"","level":"","provinceInput":"","cityInput":"","pageIndex":1,"pageSize":10,"sortField":"","sortOrder":"","page":{"begin":10,"length":10}}

提交方式

data1 = '''{"noticeTitle":"","effectTime":"","failureTime":"","noticeType":"null","purchaseNoticeType":"2","resultsNoticeType":"","level":"","provinceInput":"","cityInput":"","pageIndex":1,"pageSize":10,"sortField":"","sortOrder":"","page":{"begin":10,"length":10}}'''

requests提交

res = requests.post("http://www.tower.com.cn/default/main/index/cn.chinatowercom.obp.main.index.obphomepage.queryNoticeDetails.biz.ext",data = json.dumps(data),headers=headers,verify=False,proxies=proxies)

scrapy提交

form_data = '''{"noticeTitle":"","effectTime":"","failureTime":"","noticeType":"null","purchaseNoticeType":"2","resultsNoticeType":"","level":"","provinceInput":"","cityInput":"","pageIndex":1,"pageSize":10,"sortField":"","sortOrder":"","page":{"begin":10,"length":10}}''' full_url = "http://www.tower.com.cn/default/main/index/cn.chinatowercom.obp.main.index.obphomepage.queryNoticeDetails.biz.ext" yield scrapy.Request(full_url, callback=self.parse,body=json.dumps(form_data),method="POST",dont_filter=True)
